100 % agree. Flying GA is all about risk mitigation. We try leave room for margin for safety. This was on the edge and had the wind been stronger, temperatures warmer, or the pilot not as skillful this would have resulted in wrecked airplane and likely 4 fatalities.
@@PinkeySuavo The plane is too heavy, and/or the air too low on density, it just barely clears the treeline. The pilot should have aborted the take-off because the plane wouldn't take off the way it should have. But the pilot continued anyways, risking it all.
I was serving in the RAF, stationed in Malta, and one autumn, a hell of a storm blew up (they had to load a C130 on a dispersal pan to the max, chain her down, park two fire tenders in front of her as a windbreak, and she was *still* bouncing around like a pea on a drum). So I'm walking through the camp, leaning into the wind at a crazy angle to stop from being blown over, and I see a pilot from 39 Squadron (Photo Recon.) coming towards me. "Not taking the Canberra up today, Bob?", I asked. "Some days, Jack", he replied, "even the *birds* are walking!" Ain't that the truth.
@@marcoeland3405 it still applies. Person has an expensive plane, is probably used to being in charge, and does something cocky/stupid. Someone who has less money and more passion/experience will often fly better.
This video was filmed back in 2018 and had about 150 views until 4-5 days ago. Not sure what made the video get such attention but this was posted really to educate people about density altitude. Flying in Idaho in the summer requires some planning and in general departing Johnson Creek at 2 PM on a 90F day with a tailwing takeoff is just not a good idea. I agree with the comments about adding flaps but better to have just waited until it cooled off. I posted this video from 1966 published by the FAA. It is about a guy who coincidentally flies a 35 Bonanza with the name " Harry Bliss. " It is a very instructional video on DA and all still applies today. Be safe and always be mindful of DA. th-cam.com/video/sYrV35HCa5k/w-d-xo.html
Totally stumbled on this video by accident as an amateur flight nerd, but this is so close to me! Hope you guys stayed safe with the fires this year, excellent footage.
Get the outside air temp from your temperature probe. Get pressure altitude by setting your altimiter to 29.92. Combine the two in a flight computer to get density altitude. Use your pilot operating handbook to calculate your takeoff distance and climb rate. Add a buffer, say 10% for having an old plane. Bam, there you go.
Also, talk to the locals. They’re talking about a down-slope wind here. Mountain air currents can make your performance charts worthless. It’s possible (depending on wind speed, direction, and atmospheric stability) that the other side of the canyon has an updraft, but that also may be a turbulent mess. Avoid the Bam.
It becomes blatantly obvious how much power you no longer have in the heat at high elevations. I'm no pilot, but I'm a trucker. Starting up a grade in 90* heat in Montana or Idaho at 80k lbs, you're already prepared for the complete lack of power and the temperatures to start going up. Do the same thing in New York in the hills on a 55*-60* day and you'll understand, at least from an engine performance perspective, why heat and height are important.
I drove a new diesel-engined SUV up to the Sierra Nevada ski resort in Spain to about 10,000 feet and the engine was struggling, black smoke coming out the exhaust. The air might have been cold, but the air density was low, even breathing felt a bit strange. Then down again and the engine and myself felt a lot better!
Don't do this - take off on 17. Johnson Creek (3U2) Recommended Standard Operating Procedures Departing Runway 17 Strongly Discouraged Why? 1. Your takeoff path is directly toward the Bryant house and rising terrain. 2. Southerly winds prevail in the late afternoon. Aircraft should remain on the ground until more favorable conditions exist. 3. High density altitude conditions have contributed to several accidents at Johnson Creek.
I get how you read it but what he meant is "Don't do this (as in, don't do what's in the video) - (which is) take off on 17." But the way it's written I think it makes sense that you read it like "don't do this - take off on 17 (instead)." In which case he'd absolutely be contradicting himself.
@@Yeager123123 Nope. "This" = take off from 17. The title of this video is _Don't do this_ to which I appended "Take off on 17" which obviously means don't take off on 17. I added the airport SOP which includes "Departing Runway 17 Strongly Discouraged" which confirms "Don't do this - Take off on 17." I didn't write "INSTEAD, take off on 17." There's nothing contradictory about that.
I just tried out an online density calculator. 90 degrees Fahrenheit at 5000 feet gives a density altitude of 8038 feet. At 70 degrees, the density altitude is 6836 feet. Taking off when the weather is cooler certainly helps. Before takeoff, the pilot needs to look up several numbers in the pilot's operating handbook: "What my Bonanza's rate of climb at 8038 feet?", "What is my Bonanza's required runway length to take off from grass at 8038 feet with X knots of tailwind?", "What is my Bonanza's Vx speed for best angle of climb?", and "What is my Bonanza's maximum gross weight and have I exceeded it?". This takeoff was done on a day with high humidity. That also increases density altitude, but I don't have a way to calculate how much.
@@rylanthompson5844 And that's all before you throw in any sink from mechanical turbulence, the wind down in the canyon may not be fully indicative of what's happening up higher, basic soaring 101.
Barometric pressure changes with weather systems. The runway altitude does not change. But the pressure altitude changes a lot. This is why you must adjust the altimeter to field elevation for each departure. And also why we tune ATIS for current altimeter setting before entering the pattern. To find density-altitude, you need pressure altitude and temperature. Not field elevation. As was given above. Humidity is easy, simply find percentage, and in conjunction with temp you can find percentage water mass per cubic foot of air. Water displaces air/oxygen. But it has such a slight effect that it's not really necessary. (0.01-3% in worst case).
Aircraft that aren't super hated or turbocharged don't climb as well in less dense and hot weather. Takeoff runs are longer on grass. Some private pilot's aren't as careful as they have been taught to be.
There are charts for taking off at certain temperatures and pressures as well as on grass. Pilots are obligated by regulation to calculate takeoff distances before flying. Not only don't wings not work as well at high temperatures... normally aspirated engines also don't and altitude is a frequently recurring aviation safety topic. Furthermore, you are supposed to have a set point to abort a takeoff if it is not going well so that you don't run out of runway.
Nice. I have a soon to be 13 year old pit bull who used to do a lot of flying with me. He’s still goes up for short flights to the beach but doesn’t enjoy the camping trips out in the wilderness like he did when he was younger.
Loon Creek airstrip is about 30 miles east of there. Equally scary. Flew there in a small plane about 40 years ago. The old-timer pilot (Paul Reams) had never seen the airstrip, but absolutely refused to land there. It looked fine to us, the passengers. We landed in Challis instead. About 3 hours by car from our intended destination. Later learned from local bush pilots that our pilot made a VERY savvy decision.
I know at the old denver dragstrip was at 5800 with DAs in the 6500 range normally and a 350hp naturally aspirated engine would lose about a 100hp minimum. This might have had half his hp and in thinner air aerodynamically too...
It happened to me a few times that the conditions and runway length were not the best, and without making calculations many pilots would have decided to stay on the ground, but by consulting the POH and using as few approximations as possible it was safe to go. I don't mean to say that you MUST fly in precarious conditions, but you MUST fly using all means of threats and errors management.
He didn't turn left right away so as to 1. avoid turning sooner than necessary, 2. to position on one side of the canyon to allow room for a shallow left banking turn if necessary to turn around, 3. to avoid a head on with any inbound aircraft. Though flying a V-Tail Doctor Killer, he handled it well.
1. the "doctor killer" is a perfectly safe plane. 2. youre never turning around in that valley at that altitude and height agl. its just not an option thats why they call it "the impossible turn" under 700ft. 3. nobody is coming head on. planes takeoff and land in the same direction if you haven't noticed
“… he handled it well.” I just spat coffee all over my screen. Getting lucky is not the same as handling it well. A more appropriate analysis would be something like, “he was fortunate to be able to crawl out from the massive safety hole he dug for himself”.
Gotta retract that flap at some point. Better know Vx with both zero flaps and one notch, and be practiced at nailing your airspeed. Better yet, wait ‘til the air cools.
Hard to do it in a bonanza with electric flap lever with no detents. And the first 10 degrees take a hell of a long time to deploy. So you just either pre set it or you don’t. You don’t mess with it during your takeoff run
1 name comes to mind! HARRY BLISS!! The vintage FAA density altitude flick. “This thing has a ceiling of 20,000ft with that kind of performance we can fly anywhere”.🤣🤣🤣
More horsepower is also required to maintain flight at higher density altitude. Less HP available, more HP required, the two lines meet at absolute ceiling.
I appreciate you taking the time to read it. I can't tell you how many comments I get on this page regarding information that is contained within the description. Appreciate the kind feedback. It really is a great training video for Density Altitude.
i'd rather see a pilot keep it on the runway until he's almost out of it than horsing it off before it's ready to fly. Airspeed is more important than altitude, I don't care how close I come to something, if I'm flying in full control/have good airspeed. Not a Bonanza pilot so can't comment on the particulars about this clip.
YT just suggested this to me, good to see. Not sure how many GA accident reports have the "if only they hadn't tried to take off in the heat of mid day..." Good that they were OK, but I appreciate learning from others' close calls.
I don't know the short/soft take off procedures in a v-tail bonanza, but I didn't see any flaps which are usually a part of a short/soft field take off.
Always go early in the morning……cool air provides much better lift…and the cooler dense air makes more power…..glad my dad never flew his Bonanzas like that….😊😊
A smart pilot leaves in the early morning with cool air…I don’t care if they leave all day long….we never left in the hot air of the afternoon….my dad was smarter than that….😀
this video and description has helped me understand and picture density alt + aircraft performance way better now then how i understood it after writing and passing all my PPL theory exams. lol
It is quite possible this pilot was very good. And also thorough. Field length is given. Field elevation is given. Turf and soil condition is also self evident for anyone standing around there. Pressure altitude is found by setting altimeter to 29.92" and observing altimeter reading. Density altitude is quickly computed by any pocket calculator, slide rule, or flight related computer from pressure altitude and temperature. Gusting tailwinds are hard to quantify. But it appears to be relatively calm here. You wont find strong down-drafts just randomly on a hot afternoon. There will be strong updrafts where the sun is shining (this runway) and the downdrafts will be in the shade. Usually along north facing slopes. The fact this fellow had maximum power with brakes applied. Did not choose to set takeoff flaps (for specific reasons, mostly due to excess drag including induced drag from destroying your span-wise lift distribution with flaps deflected). He does not force the rotation. Be does not raise the nose too high. He gently coaxes the aircraft off the grads, into ground effect. Allows speed to build gradually, without the grass slowing him down. He establishes a gentle rate of climb that allows him to clear the trees by a comfortable 100' (3x tree height). And he does not get greedy andtey to climb steeper at a potentially lethal Vx, as suggested above. (Backside of power curve, excessive induced drag, close to stall, with no way out except to nose over). This pilot established a respectable 500fpm cruise-climb rate. At higher speed and shallow angle of attack. And simply climbed over the trees with plenty of airspeed to handle a gust or downdraft. Everyone standing around, armchair pontificating about the performance of an aircraft they have never even flown or opened the POH for. Judging another pilots ability, experience, knowledge of his craft, and his ADM judgement based on their own limited knowledge of their own antique airplane, which does have nor ever included a POH. Because they were sold before this was even a requirement. Most of those planes lack graphs and charts and engineering level performance data which Beechcraft alone, and no other manufacture, includes with their aircraft. Most older Cessnas and pipers, bellancas and Stinsons you are lucky to get single data points printed, such as Vx, Vy, Vne. Which do not tel the tale, and will lead pilots to make very poor use of their airplanes. Such as attempting a Vx takeoff as high density altitude with trees at the end of a plenty-long 3/4 mile runway.
He also took the right side of the valley, vs turning in the center, which is what you should do in narrow cannon/valleys. Two things about that, that make it the right thing to do, and this pilot Monday quarter backing brought it up… if he is concerned about “sinkers” come from the left, then you want to be on the opposite side where the lift is happening. Additionally, you should never fly in the center of a narrow valley, that’s where mid-airs happen. Also, flying as far over to one side, gives you more room to maneuver if you need to turn back. I honestly didn’t see anything wrong with the pilots actions. He got off 3/4 of the runway, he stayed to the right of the valley away from down drafts, avoiding head on traffic situation, and giving more room for maneuvering.
@@bearb1asting I think that’s coming from someone that knows bonanza aircraft. I’ve only got a little over 20 hours in a bonanza but he’s 100% right about bonanza performance charts and he appears to have knowledge on Johnson strip. As for my comment, it is about general mountain flying and from what I can see, the pilot made the right choices as far as his path out.
Right. If eleven contributing factors are perfect, the performance of this aircraft is at book data or better, and the engine, gear and flaps work perfectly, and EVERY move that the pilot makes is absolutely flawless, then there'll be no problem. I wonder how important it was to arrive at his destination on time?
I think this pilot was actually quite skilled. The way he contoured the hills flying northerly toward higher terrain took good airmanship/mountain flying experience. If you know this pilot or are the pilot I would love to hear about this flight from that perspective. I wish I could say that I have made perfect ADM (Aeronautical decision making) choices every time I flew but I would be lying. We all need to learn from our mistakes I am going to post this video on BeechTalk once it hits 1 million views. Just for fun. Hopefully find the pilot. My hope is this video will serve as an instructional source for everyone to learn about DA.
If level in low ground effect takeoff is not default, the extra acceleration energy of low ground effect will not be there when we need it. Gear is as much drag when rolling on wheels as when in low ground effect so does not have to come up quickly, or can if needed. Planning and waiting is better but default low ground effect is a good technique for disorganized or impatent pilots as well.
Jim. I agree this pilot had some skill. But he made a bad decision to takeoff at the highest DA of the day with a quartering tailwind in a loaded Bonanza with 4 adults. Good technique with a low ground effect takeoff. Good choice to head up the canyon and get some lift off the ridge from the southeasterly winds. But that’s just not good ADM. Not a lot of margin. My guess is this pilot was sweating balls after he was wheels up and this flight scared the bejesus out of him. I put it up on the channel so that people could really see the effect of DA on performance and hopefully launch on cool mornings with light loads. Give yourself lots of margin.
Yes, Josh, you are correct. I assumed he was taking off down drainage as well. Crop dusting I worked low ground effect to near the limit, but I was always single pilot.@@dogismycoolpilot9662
Sometimes a pilot gets away with it but when it's this close to disaster just wait for better conditions. If this is how the pilot always fly's he will come to a point were some unexpected wind goes against him, more margin needed I think. @@dogismycoolpilot9662
@@dogismycoolpilot9662 I would have liked to see him use elevator to get up six inches and level in low ground earlier, but complex guys don't always see than ground effect energy is greater than drag of gear. And that Mooney guy on BCP did both low ground effect and gear up. What pitching up before Vso into low ground effect tells us, should it not happen before mid point, is that we need to abort. And yes, prior planning prevents pitifully poor performance. I was a pipeline patrol pilot. We flew in wind, heat of day, and low ceilings. High DA might require down drainage, as did the Bonanza, and then come back around to the pipeline right of way. Glad this came up again. Miss your comments.
The DA was about 8200 feet on takeoff. The airplane was loaded with 4 adults - not sure about the amount of fuel. I thought he might have been in a turbocharged airplane when he first started the roll but could tell he wasn't after making an anemic ground run. I am going to guess this pilot learned his lesson after his balls were riding high in the back of his throat clearing that terrain. My Skywagon on a cool morning can climb straight over the hill directing in front of runway 35 just for some reference. Similar engine in a 35 Bonanza. The Skywagon is a better climbing airplane but a Bonanza would normal ease off the runway at Johnson Creek with cooler temps. Good lesson for anyone regarding DA (density altitude). Why I posted the video.
After googling the airport that is some very rough retain to fly around. I would double check all my numbers before taking off. Great video. @@dogismycoolpilot9662
I would say both too high. But there is no point in climbing at best angle if you don't have to, he's gaining airspeed and then doing a gentle climb. But its obviously not got excessive power because he used 10 miles of runway.
DA 8200? Wow! You'd be lucky to launch a child's kite in a 20 knot wind, wouldn't you? If you could, you'd be well and truly out of breath by the time it took flight.@@dogismycoolpilot9662
Density altitude take off with passengers. On rotation, 1)gear up to eliminate drag, 2) increase airspeed and finally turn out and climb, standard procedure
Just because he didn't crash doesn't mean it is advisable. Also there is still some valuable learning from this, about DA as mentioned before. Maybe it's not the done thing, but I would have looked for a pilot on the strip with more experience there and had a chat about taking off from that strip. Never hurts to ask.
Very interesting to see. Thanks for posting! I'm super happy to see that this didn't result in a mishap. I've edited my post as I'm a non pilot and had to educate myself on the phenomenon of "Density Altitude" I think this pilot might be safer if they did a little research like I did. 🤔.
The 50 70 rule was not taught when I took ground school back in the 70's. I hope it is now and should be part of a biannual flight review. It seems like this would have helped our tree-dragging pilot.
I can't escape from thinking this was simply a more challenging scenario, consciously and expertly taken on by a skilled pilot. I also find it humorous how all of the pilot's very correct actions are criticized as mistakes, in order, by the people speaking in the video.
@@ntdfmaverick read some mountain flying books Look at the loaded 206 that just crashed killing 2 people at this airport 3 weeks ago Or the 182 at big creek on Father’s Day Pilots are making errors Experience pilots as well In general you do not fly in the afternoons In general you do not take off loaded In general you do not takeoff when it’s 90 degrees F In general don’t take off with a tailwind The bonanza pilot has all of this contributing factors For every plane crash with fatalities there are several like this where they escape Read the description I wrote I gave credit to the pilot for his skill Safety is about margins This was too thin a margin for most people Let alone the pilot and 3 passengers The intention of the video is to show accepted practices for DA Not razor thin margins of safety If you want to learn more read any of the work by Amy Hoover, or Lori McNichol We will continue to see deaths every year in Idaho precisely because people either think they have a margin of safety that is much less or don’t understand DA at all and wing it either is not acceptable I also fly high risk missions and am speaking as someone who teaches backcountry and mountain flying
@peanuts2105 - you need *lift* to get over a mountain, and the two critical factors for producing lift for any given aircraft are air pressure and air temperature. The combination of high air temperature *AND* high altitude has killed a hell of a lot of pilots who failed to grasp that - and the pilot had ample room and time to realise that he was pushing his luck and abort.
At least they turned on the sprinklers during his departure, that helped cool it down a bit.... On another note, 0:25 that lady is sucking back some wine and chomping on an oversized ham sammie.... I mean, dayuumm that's a big sammie!!! 😶
That Bone-Anza’s engine has at least one weak cylinder. I’ve experienced that. It will pass the run-up mag check, RPM drop. In the air it just won’t climb.
Maybe not over gross, but 90F air temp, 5'000 alt runway, tailwind, grass, not lightly loaded, lot's of factor's stacked against the pilot this day@@ChefDuane
DA aside, has this guy ever heard of a soft field takeoff? Doesn't look like any elevon applied whatsoever. No flaps either, but not sure if the POH calls for it on these V35's. Agree with others saying at least build up some speed, then feed some flaps in.
Perspective is a factor here. When skydiving and under canopy, I thought that the jumpers beneath me were sure to hit the trees. Of course they were hundreds/thousands of feet above them but it’s amazing how close it looks.
The old 150 I owned for 20 years climbed out better than that on its worse day. There sure must have been some High / hot issues going on to make Bonanza wallow away like that.
I don’t know the other factors like elevation, temperature, etc, but looking the sprinklers drifting water, in the direction of his takeoff, I looks like a downwind takeoff.
I have very little (none among mountains) experience with short take off on turf airfield. I've performed one landing, or takeoff. My limited experience would have caused me to proceed with revving engine with brakes on, one knotch of flaps, releasing brakes, holding rotation at ground effect up to one third remaining airfield to increase air speed up to Vy (76-80kts) before climb out. Only remove flap after steady climbing. My area of country is very hot, humid, training in 180hp Cessna. So, does this sound like it would work in mountains under this videos pilot conditions?
Think Density Altitude. 5000 foot airport elevation, temp 90 degrees, depending on barometric pressure (altimeter setting) the density altitude for this takeoff was 8000- 10,000 ft. or more. At that altitude you should be leaning the engine for best power before takeoff. Also, at high altitudes Vy is slightly reduced, coming closer to Vx with the two being equal at the aircraft's absolute operating ceiling. Don't let it get too slow though as stalls require even more altitude for recovery in the thin air. Much better to wait for lower temperature and less tail wind for the takeoff.
@@fast_richard Thank you. Your experience and others advice would be the key to a successful take off. I would mostly avoid any situation where I take off at those attitudes given my experience is no higher than 20-300ft MSL attitudes. Some hot humid days the climb out is lowered significantly, but not to your degree of challenge above trees in mountainous terrain. Example of my area follows: Elev20ft, Temp 33°c DA2100.
This video was at Johnson Creek, ID. 3400' grass in very good condition, but 5000' elevation! Density altitude is a big concern. Very hot during the summer. Best to land upstream, and depart down stream. You want to arrive early, and depart early. If that Bonanza had taken off into the wind (upstream) it might not have climbed the slope up the canyon, and it's narrow...not a good combination.
@@patjanders So at 5000ft elevation do you Lean the mixture at take off? I'm use to full rich take off and only begin leaning the mixture above 3000ft elevation.
@@dilbertjunkmail At full takeoff power you want to run full rich. The problem is that at higher elevations you cannot get full takeoff power. If you are at an altitude or elevation where the maximum power you can get is in the range where leaning is required, that is when it is time to lean for max power on the ground before takeoff. The exact elevation where you switch to leaning before takeoff depends on the particular engine and installation and is keyed to density altitude. This only applies to normally aspirated engines. For turbo-charged engines refer to the operator's manual. For more complete info on leaning practices see the publications and videos from Mike Busch of Savvy aviation. Most pilots and instructors do not understand proper modern leaning procedures.
Gee, 90° F. Wonder what the density altitude was. A rough guess would be 8,315 MSL. That's about 3,335 feet higher than the field elevation of 4,980 feet.
Sometimes I wonder if anyone paid attention in ground school. They’re probably at least 5k feet and sprinklers are running increasing the humidity. High, Hot, Humid anyone?…
They don't even know what the difference between a man and woman is anymore and you expect them to know how to fly a plane????? Good luck bro, the only good business these days is the funeral business. Better to be a mortician than a pilot.
@@okbuddyretard yeah dude I got sick and tired of dumb@zz’s not following procedures taking off downwind head on into the path of other aircraft taking off.

In other words individuals who have no business whatsoever being at the controls of any aircraft. Are you one of those individuals?
Videos like this are 100% equally as important as accident case studies. Just because a disaster didn't happen didn't mean it wasn't totally wrong.
100 % agree. Flying GA is all about risk mitigation. We try leave room for margin for safety. This was on the edge and had the wind been stronger, temperatures warmer, or the pilot not as skillful this would have resulted in wrecked airplane and likely 4 fatalities.

Get the outside air temp from your temperature probe. Get pressure altitude by setting your altimiter to 29.92. Combine the two in a flight computer to get density altitude. Use your pilot operating handbook to calculate your takeoff distance and climb rate. Add a buffer, say 10% for having an old plane. Bam, there you go.
Id say boom but dont know bout the pilot
T/O into the wind
@@tmayorca8770 That too
So that was what the section on the Kane was for.
Also, talk to the locals. They’re talking about a down-slope wind here. Mountain air currents can make your performance charts worthless.
It’s possible (depending on wind speed, direction, and atmospheric stability) that the other side of the canyon has an updraft, but that also may be a turbulent mess.

It becomes blatantly obvious how much power you no longer have in the heat at high elevations. I'm no pilot, but I'm a trucker. Starting up a grade in 90* heat in Montana or Idaho at 80k lbs, you're already prepared for the complete lack of power and the temperatures to start going up. Do the same thing in New York in the hills on a 55*-60* day and you'll understand, at least from an engine performance perspective, why heat and height are important.
I drove a new diesel-engined SUV up to the Sierra Nevada ski resort in Spain to about 10,000 feet and the engine was struggling, black smoke coming out the exhaust. The air might have been cold, but the air density was low, even breathing felt a bit strange. Then down again and the engine and myself felt a lot better!
Imagine if the motor only moved you forward and you needed the air pressure/density for the elevation gain.
Great post. 1:08 I had not ever considered heat affecting my pickup's performance while towing. Alltitude, yes. But temperature, no. Thanks for this.
how bout flaps ? I don't remember seeing them.
It looks like the PILOT checked that the flaps were UP. Do YOU think that a high rate of climb would be desirable?

Don't do this - take off on 17.
Johnson Creek (3U2)
Recommended Standard Operating Procedures
Departing Runway 17
Strongly Discouraged
Why?
1. Your takeoff path is directly toward the Bryant house and rising terrain.
2. Southerly winds prevail in the late afternoon. Aircraft should remain on the ground until more favorable conditions exist.
3. High density altitude conditions have contributed to several accidents at Johnson Creek.
Did you contradict yourself or am I reading your comment wrong?
@@Yeager123123 How so?
@@smark1180 You said to take off on 17 and then put that Departing Runway 17 is strongly discouraged.
I get how you read it but what he meant is "Don't do this (as in, don't do what's in the video) - (which is) take off on 17."
But the way it's written I think it makes sense that you read it like "don't do this - take off on 17 (instead)." In which case he'd absolutely be contradicting himself.
@@Yeager123123 Nope. "This" = take off from 17.
The title of this video is _Don't do this_ to which I appended "Take off on 17" which obviously means don't take off on 17. I added the airport SOP which includes "Departing Runway 17 Strongly Discouraged" which confirms "Don't do this - Take off on 17." I didn't write "INSTEAD, take off on 17."
There's nothing contradictory about that.

Looks very similar to Hope Bc airport
I just tried out an online density calculator. 90 degrees Fahrenheit at 5000 feet gives a density altitude of 8038 feet. At 70 degrees, the density altitude is 6836 feet. Taking off when the weather is cooler certainly helps.
Before takeoff, the pilot needs to look up several numbers in the pilot's operating handbook: "What my Bonanza's rate of climb at 8038 feet?", "What is my Bonanza's required runway length to take off from grass at 8038 feet with X knots of tailwind?", "What is my Bonanza's Vx speed for best angle of climb?", and "What is my Bonanza's maximum gross weight and have I exceeded it?".
This takeoff was done on a day with high humidity. That also increases density altitude, but I don't have a way to calculate how much.
This one includes the dew point: www.weather.gov/epz/wxcalc_densityaltitude
You forgot barometric pressure
@@rylanthompson5844 And that's all before you throw in any sink from mechanical turbulence, the wind down in the canyon may not be fully indicative of what's happening up higher, basic soaring 101.
@@rylanthompson5844 Barometic pressure is exactly what the 8038 number represents.
Barometric pressure changes with weather systems. The runway altitude does not change. But the pressure altitude changes a lot. This is why you must adjust the altimeter to field elevation for each departure. And also why we tune ATIS for current altimeter setting before entering the pattern.
To find density-altitude, you need pressure altitude and temperature. Not field elevation. As was given above.
Humidity is easy, simply find percentage, and in conjunction with temp you can find percentage water mass per cubic foot of air. Water displaces air/oxygen. But it has such a slight effect that it's not really necessary. (0.01-3% in worst case).
"He needs to just stop" Lol. Sounds like something my wife would say if I brought her to a fly-in
At the point she said that he was going flying or dying. No stopping when you are 3/4 down the runway at full tilt.
She means he should have aborted the takeoff
He was fine. It’s all down hill from there with plenty of big bowls to make a turn around in. You never trade airspeed for altitude.
i would have flown in ground effect longer to gain even more airspeed, then climb out.
Unless you're gonna hit a mountain!

I know nothing about planes but I had to click on this just because of the beautiful view. Now I also learned a bit in the process.
Aircraft that aren't super hated or turbocharged don't climb as well in less dense and hot weather. Takeoff runs are longer on grass. Some private pilot's aren't as careful as they have been taught to be.
There are charts for taking off at certain temperatures and pressures as well as on grass. Pilots are obligated by regulation to calculate takeoff distances before flying. Not only don't wings not work as well at high temperatures... normally aspirated engines also don't and altitude is a frequently recurring aviation safety topic. Furthermore, you are supposed to have a set point to abort a takeoff if it is not going well so that you don't run out of runway.

Nice. I have a soon to be 13 year old pit bull who used to do a lot of flying with me. He’s still goes up for short flights to the beach but doesn’t enjoy the camping trips out in the wilderness like he did when he was younger.
Is he on Galliprant? Its great for doggie arthritis.
Loon Creek airstrip is about 30 miles east of there. Equally scary. Flew there in a small plane about 40 years ago. The old-timer pilot (Paul Reams) had never seen the airstrip, but absolutely refused to land there. It looked fine to us, the passengers. We landed in Challis instead. About 3 hours by car from our intended destination. Later learned from local bush pilots that our pilot made a VERY savvy decision.
I refused to land at Paradise Airport for the same reason. It's a 1200' one-direction runway with a cliff on the end you take off and land from.
I know at the old denver dragstrip was at 5800 with DAs in the 6500 range normally and a 350hp naturally aspirated engine would lose about a 100hp minimum.
This might have had half his hp and in thinner air aerodynamically too...
It happened to me a few times that the conditions and runway length were not the best, and without making calculations many pilots would have decided to stay on the ground, but by consulting the POH and using as few approximations as possible it was safe to go. I don't mean to say that you MUST fly in precarious conditions, but you MUST fly using all means of threats and errors management.
One of the worse things in aviation is having your peers critiquing your lack of skills/judgement. The worse is dying from them.
“You miss 100% of the takeoffs you don’t take”

Plane Gretzky shouted some wisdom as he passed by in this video.. but it was difficult to hear him over the Karen noises and the clucking hen sounds
Yea but you survive 100 % of the takeoffs you don't take. This takeoff I'd rather miss and survive.
That makes absolutely no sense.
My Dad did the same thing the same thing in our 182M flying out of Happy Camp CA. He used the slope lift get out of the valley.
He didn't turn left right away so as to 1. avoid turning sooner than necessary, 2. to position on one side of the canyon to allow room for a shallow left banking turn if necessary to turn around, 3. to avoid a head on with any inbound aircraft. Though flying a V-Tail Doctor Killer, he handled it well.
1. the "doctor killer" is a perfectly safe plane. 2. youre never turning around in that valley at that altitude and height agl. its just not an option thats why they call it "the impossible turn" under 700ft. 3. nobody is coming head on. planes takeoff and land in the same direction if you haven't noticed
@@Sammyb_rc I think I may be missing something, but I'm confused as to what you think is going here.
“… he handled it well.”
I just spat coffee all over my screen. Getting lucky is not the same as handling it well. A more appropriate analysis would be something like, “he was fortunate to be able to crawl out from the massive safety hole he dug for himself”.
Go with zero flap during acceleration and apply first level as you rotate. Less drag - more lift.
haha
Gotta retract that flap at some point. Better know Vx with both zero flaps and one notch, and be practiced at nailing your airspeed. Better yet, wait ‘til the air cools.
soft field so not really
@@russbell6418Park it and have one of those yummy looking sammiches!
Hard to do it in a bonanza with electric flap lever with no detents. And the first 10 degrees take a hell of a long time to deploy. So you just either pre set it or you don’t. You don’t mess with it during your takeoff run
This was most likely a density altitude problem as the Bonanza was unable to climb.

Incredible write-up in the description. Thanks for that
I appreciate you taking the time to read it. I can't tell you how many comments I get on this page regarding information that is contained within the description. Appreciate the kind feedback. It really is a great training video for Density Altitude.
i'd rather see a pilot keep it on the runway until he's almost out of it than horsing it off before it's ready to fly. Airspeed is more important than altitude, I don't care how close I come to something, if I'm flying in full control/have good airspeed. Not a Bonanza pilot so can't comment on the particulars about this clip.
Isn't this at Yellow Pine, Idaho? I have flown into this airport!
And no flaps.
YT just suggested this to me, good to see. Not sure how many GA accident reports have the "if only they hadn't tried to take off in the heat of mid day..." Good that they were OK, but I appreciate learning from others' close calls.
Density altitude is a factor here..too much runway being used.
That's what I was thinking, 90F day and he sure used a lot of runway. I think I'd wait until tomorrow at first light.
The description was a long read, but I'm glad I went thru it
Shouldnt you have flaps set for a soft field departure? That was a close one!!
... even build up speed... THEN apply flaps partway down the runway for lift... either way, pilot had NO margin for recovery there.
Density altitude issue, if anything. That strip isn't soft and likely is not even wet - with watering in progress nearby.
@@cdncitizen4700he’s fine😂😂😂
For whatever reason Beech omitted the use of flaps for takeoff in the POH.
I don't know the short/soft take off procedures in a v-tail bonanza, but I didn't see any flaps which are usually a part of a short/soft field take off.
It wasn't a short field, more like a density altitude situation with a loaded aircraft.
Always go early in the morning……cool air provides much better lift…and the cooler dense air makes more power…..glad my dad never flew his Bonanzas like that….😊😊
Planes take off all hours of the day & night.
A smart pilot leaves in the early morning with cool air…I don’t care if they leave all day long….we never left in the hot air of the afternoon….my dad was smarter than that….😀
Not at high density altitude they don’t….thats how you die…it’s apparent that you don’t know much about flying
this video and description has helped me understand and picture density alt + aircraft performance way better now then how i understood it after writing and passing all my PPL theory exams. lol
It is quite possible this pilot was very good. And also thorough.
Field length is given. Field elevation is given. Turf and soil condition is also self evident for anyone standing around there.
Pressure altitude is found by setting altimeter to 29.92" and observing altimeter reading.
Density altitude is quickly computed by any pocket calculator, slide rule, or flight related computer from pressure altitude and temperature.
Gusting tailwinds are hard to quantify. But it appears to be relatively calm here.
You wont find strong down-drafts just randomly on a hot afternoon. There will be strong updrafts where the sun is shining (this runway) and the downdrafts will be in the shade. Usually along north facing slopes.
The fact this fellow had maximum power with brakes applied. Did not choose to set takeoff flaps (for specific reasons, mostly due to excess drag including induced drag from destroying your span-wise lift distribution with flaps deflected).
He does not force the rotation. Be does not raise the nose too high. He gently coaxes the aircraft off the grads, into ground effect. Allows speed to build gradually, without the grass slowing him down. He establishes a gentle rate of climb that allows him to clear the trees by a comfortable 100' (3x tree height). And he does not get greedy andtey to climb steeper at a potentially lethal Vx, as suggested above. (Backside of power curve, excessive induced drag, close to stall, with no way out except to nose over).
This pilot established a respectable 500fpm cruise-climb rate. At higher speed and shallow angle of attack. And simply climbed over the trees with plenty of airspeed to handle a gust or downdraft.
Everyone standing around, armchair pontificating about the performance of an aircraft they have never even flown or opened the POH for. Judging another pilots ability, experience, knowledge of his craft, and his ADM judgement based on their own limited knowledge of their own antique airplane, which does have nor ever included a POH. Because they were sold before this was even a requirement.
Most of those planes lack graphs and charts and engineering level performance data which Beechcraft alone, and no other manufacture, includes with their aircraft. Most older Cessnas and pipers, bellancas and Stinsons you are lucky to get single data points printed, such as Vx, Vy, Vne. Which do not tel the tale, and will lead pilots to make very poor use of their airplanes. Such as attempting a Vx takeoff as high density altitude with trees at the end of a plenty-long 3/4 mile runway.
He also took the right side of the valley, vs turning in the center, which is what you should do in narrow cannon/valleys. Two things about that, that make it the right thing to do, and this pilot Monday quarter backing brought it up… if he is concerned about “sinkers” come from the left, then you want to be on the opposite side where the lift is happening. Additionally, you should never fly in the center of a narrow valley, that’s where mid-airs happen. Also, flying as far over to one side, gives you more room to maneuver if you need to turn back. I honestly didn’t see anything wrong with the pilots actions. He got off 3/4 of the runway, he stayed to the right of the valley away from down drafts, avoiding head on traffic situation, and giving more room for maneuvering.
Did we find the pilot here? That's some oddly specific knowledge
@@bearb1asting I think that’s coming from someone that knows bonanza aircraft. I’ve only got a little over 20 hours in a bonanza but he’s 100% right about bonanza performance charts and he appears to have knowledge on Johnson strip. As for my comment, it is about general mountain flying and from what I can see, the pilot made the right choices as far as his path out.
Right. If eleven contributing factors are perfect, the performance of this aircraft is at book data or better, and the engine, gear and flaps work perfectly, and EVERY move that the pilot makes is absolutely flawless, then there'll be no problem.
I wonder how important it was to arrive at his destination on time?
“There are old pilots, and there are bold pilots, but there are no old bold pilots.” - old flying saying.

Taking off at an elevated altitude on a hot day in Idaho with no flaps - what could possibly go wrong?
Little did they know the Pilot has over 10,000 hours flight time in GTA5
I think this pilot was actually quite skilled. The way he contoured the hills flying northerly toward higher terrain took good airmanship/mountain flying experience. If you know this pilot or are the pilot I would love to hear about this flight from that perspective. I wish I could say that I have made perfect ADM (Aeronautical decision making) choices every time I flew but I would be lying. We all need to learn from our mistakes
I am going to post this video on BeechTalk once it hits 1 million views. Just for fun. Hopefully find the pilot. My hope is this video will serve as an instructional source for everyone to learn about DA.
Well, 10,000 hours did not help him choose a plane suited for those conditions and terrain.
Density Altitude and Over Gross. Happens in the mountains all the time. Can't get out with the same gross you came in with especially on a hot day.
Legend has it that Bonanza is still out there, trying desperately to climb up to 50ft.....😊😮
NEVER FORGET TO CALCULATE DENSITY ALTITUDE AND W&B !!!
no flaps?
If level in low ground effect takeoff is not default, the extra acceleration energy of low ground effect will not be there when we need it. Gear is as much drag when rolling on wheels as when in low ground effect so does not have to come up quickly, or can if needed. Planning and waiting is better but default low ground effect is a good technique for disorganized or impatent pilots as well.
Jim. I agree this pilot had some skill. But he made a bad decision to takeoff at the highest DA of the day with a quartering tailwind in a loaded Bonanza with 4 adults. Good technique with a low ground effect takeoff. Good choice to head up the canyon and get some lift off the ridge from the southeasterly winds. But that’s just not good ADM. Not a lot of margin. My guess is this pilot was sweating balls after he was wheels up and this flight scared the bejesus out of him. I put it up on the channel so that people could really see the effect of DA on performance and hopefully launch on cool mornings with light loads. Give yourself lots of margin.
Yes, Josh, you are correct. I assumed he was taking off down drainage as well. Crop dusting I worked low ground effect to near the limit, but I was always single pilot.@@dogismycoolpilot9662
Sometimes a pilot gets away with it but when it's this close to disaster just wait for better conditions. If this is how the pilot always fly's he will come to a point were some unexpected wind goes against him, more margin needed I think. @@dogismycoolpilot9662
@@dogismycoolpilot9662 I would have liked to see him use elevator to get up six inches and level in low ground earlier, but complex guys don't always see than ground effect energy is greater than drag of gear. And that Mooney guy on BCP did both low ground effect and gear up. What pitching up before Vso into low ground effect tells us, should it not happen before mid point, is that we need to abort. And yes, prior planning prevents pitifully poor performance. I was a pipeline patrol pilot. We flew in wind, heat of day, and low ceilings. High DA might require down drainage, as did the Bonanza, and then come back around to the pipeline right of way. Glad this came up again. Miss your comments.
Wonder what the density altitude was and his weight.
The DA was about 8200 feet on takeoff. The airplane was loaded with 4 adults - not sure about the amount of fuel. I thought he might have been in a turbocharged airplane when he first started the roll but could tell he wasn't after making an anemic ground run. I am going to guess this pilot learned his lesson after his balls were riding high in the back of his throat clearing that terrain. My Skywagon on a cool morning can climb straight over the hill directing in front of runway 35 just for some reference. Similar engine in a 35 Bonanza. The Skywagon is a better climbing airplane but a Bonanza would normal ease off the runway at Johnson Creek with cooler temps. Good lesson for anyone regarding DA (density altitude). Why I posted the video.
After googling the airport that is some very rough retain to fly around. I would double check all my numbers before taking off. Great video. @@dogismycoolpilot9662
I would say both too high. But there is no point in climbing at best angle if you don't have to, he's gaining airspeed and then doing a gentle climb. But its obviously not got excessive power because he used 10 miles of runway.
4 adults? Seems irresponsible.
DA 8200? Wow! You'd be lucky to launch a child's kite in a 20 knot wind, wouldn't you? If you could, you'd be well and truly out of breath by the time it took flight.@@dogismycoolpilot9662
Density altitude take off with passengers. On rotation, 1)gear up to eliminate drag, 2) increase airspeed and finally turn out and climb, standard procedure

Just because he didn't crash doesn't mean it is advisable. Also there is still some valuable learning from this, about DA as mentioned before. Maybe it's not the done thing, but I would have looked for a pilot on the strip with more experience there and had a chat about taking off from that strip. Never hurts to ask.
Why didn't the pilot have flaps deployed?
to gain airspeed faster.
Super cool spot! I flew in last summer. Would never roll out at 2pm and 90 degrees. Just not enough margin to absorb any errors.
Don't do what?
Eat front of the camera a sandwich.
Very interesting to see. Thanks for posting! I'm super happy to see that this didn't result in a mishap. I've edited my post as I'm a non pilot and had to educate myself on the phenomenon of "Density Altitude" I think this pilot might be safer if they did a little research like I did. 🤔.
The 50 70 rule was not taught when I took ground school back in the 70's. I hope it is now and should be part of a biannual flight review. It seems like this would have helped our tree-dragging pilot.

Just keep the airspeed up, the rest will follow. Personally, if its hot and you are heavy, takeoff in the morning
It's IAS so the same airspeed regardless of D.A.
@peanuts2105 - you need *lift* to get over a mountain, and the two critical factors for producing lift for any given aircraft are air pressure and air temperature. The combination of high air temperature *AND* high altitude has killed a hell of a lot of pilots who failed to grasp that - and the pilot had ample room and time to realise that he was pushing his luck and abort.

"V-tailed doctor killers"
That airport remains of watching the spirit of Saint Louis cut it slim
Or Doolittle's B25s getting airborne off the Hornet.
I have very little (none among mountains) experience with short take off on turf airfield. I've performed one landing, or takeoff.
My limited experience would have caused me to proceed with revving engine with brakes on, one knotch of flaps, releasing brakes, holding rotation at ground effect up to one third remaining airfield to increase air speed up to Vy (76-80kts) before climb out. Only remove flap after steady climbing. My area of country is very hot, humid, training in 180hp Cessna.
So, does this sound like it would work in mountains under this videos pilot conditions?
Think Density Altitude. 5000 foot airport elevation, temp 90 degrees, depending on barometric pressure (altimeter setting) the density altitude for this takeoff was 8000- 10,000 ft. or more. At that altitude you should be leaning the engine for best power before takeoff. Also, at high altitudes Vy is slightly reduced, coming closer to Vx with the two being equal at the aircraft's absolute operating ceiling. Don't let it get too slow though as stalls require even more altitude for recovery in the thin air. Much better to wait for lower temperature and less tail wind for the takeoff.
@@fast_richard Thank you. Your experience and others advice would be the key to a successful take off. I would mostly avoid any situation where I take off at those attitudes given my experience is no higher than 20-300ft MSL attitudes. Some hot humid days the climb out is lowered significantly, but not to your degree of challenge above trees in mountainous terrain. Example of my area follows: Elev20ft, Temp 33°c DA2100.
This video was at Johnson Creek, ID. 3400' grass in very good condition, but 5000' elevation! Density altitude is a big concern. Very hot during the summer. Best to land upstream, and depart down stream. You want to arrive early, and depart early. If that Bonanza had taken off into the wind (upstream) it might not have climbed the slope up the canyon, and it's narrow...not a good combination.
@@patjanders So at 5000ft elevation do you Lean the mixture at take off?
I'm use to full rich take off and only begin leaning the mixture above 3000ft elevation.
@@dilbertjunkmail At full takeoff power you want to run full rich. The problem is that at higher elevations you cannot get full takeoff power. If you are at an altitude or elevation where the maximum power you can get is in the range where leaning is required, that is when it is time to lean for max power on the ground before takeoff. The exact elevation where you switch to leaning before takeoff depends on the particular engine and installation and is keyed to density altitude. This only applies to normally aspirated engines. For turbo-charged engines refer to the operator's manual.
For more complete info on leaning practices see the publications and videos from Mike Busch of Savvy aviation. Most pilots and instructors do not understand proper modern leaning procedures.
Gee, 90° F. Wonder what the density altitude was. A rough guess would be 8,315 MSL. That's about 3,335 feet higher than the field elevation of 4,980 feet.
The peanut gallery has no idea what’s actually going on in the cockpit. It’s hard to argue with a successful outcome.
It’s very important to check air density and weight.
They say he’s still trying to climb😂
They really don't but maybe you'll have an original thought one day.
@@markfox1545 you must be fun at a BBQ
Good one! I got a good laugh out of that one.
😂😂😂
Sometimes I wonder if anyone paid attention in ground school. They’re probably at least 5k feet and sprinklers are running increasing the humidity. High, Hot, Humid anyone?…
Man, everyone's an effing expert
Where is this ? Looks beautiful. Idaho ?
Johnson Creek, Idaho
Van Nuys airport.
Pilots like this are the reason I left the flying game after twenty five years. It gets worse everyday.
They don't even know what the difference between a man and woman is anymore and you expect them to know how to fly a plane????? Good luck bro, the only good business these days is the funeral business. Better to be a mortician than a pilot.
You stopped flying because of other pilots? Lmao.
@@okbuddyretard yeah dude I got sick and tired of dumb@zz’s not following procedures taking off downwind head on into the path of other aircraft taking off. Pilots not making radio calls individuals flying right traffic pattern instead of the published left traffic. Individuals who can’t understand what ATC is instructing them to do. In other words individuals who have no business whatsoever being at the controls of any aircraft. Are you one of those individuals?
Nice story that never happened
