At approximately 14:00 you flew over a valley where I lived on a homestead for 12 years. It was great to see as it brought back many memories. Thank you.
Maybe it is because I do most of my flying in the mountains; but it looked like a fairly normal landing to me (except for restricting flaps to 10*). Looking forward to the mystery takeoff
Watching these videos makes me feel like going back to fly small airplanes and enjoy the view from there. Great and very entertaining videos. Good job.
Nice movie. I like how you analise the situation. Although you state in the start that the movies are not for instruction, for obvious reasons, they can be very instructive. Like this one and the next two movies, the aborted takeoff and the actual takeoff in the next day. Useful lessons there. Just got yourself another subscriber. I'm a commercial pilot and flight instructor from Brasil.
NO WAY!!!! I was born in KPSP and I noticed you made a stop in either KUDD or Jackie cockoran! I'm currently in KSEA but I'm so happy to see you in my old haunts!
By the way, I landed a couple of weeks ago in my club's 172 P on RWY 18 with the wind blowing 19 gusting to 30 from 220°. It was exciting. My son, who is post solo in his primary training was very impressed. I was just glad to be on the ground.
Two landings! LOL! My Buddy who flew a 172 RG told me one time when he did the two landings that he 'liked the first one so much he decided to do it again. :) Sorry you are not a home to show us some aerial pictures of the devastation left by the floods. Hope your folks are alright!
I live up in the forest about straight off the wing at 16:22 (you can see the roads perpendicular to the plane up closer to the mountains). The weather up here can change quickly, but we do have about 330 days of sunshine a year, so you picked one of the 30 or so bad weather days.
That was awesome the take of was the best 30-40 seconds of the vid and a good rotation off the ground also the landing was a little bumpy with up drafts and a left crosswind but you still made the centre line nice work josh can't wait for the next video of your epic journey :D
Not fair Josh! Next time you ever come out to California come to Oxnard or Camarillo, I really want to meet up with you!!! It kills me knowing how close Big Bear is. :( MrAviation101
Did my long (250nm) XC today for Commercial training. On the way out I was going 85kt GS (c152), it was rough lol. I saw 123kt on the way home at 7,500 for about 30 seconds, I got very excited xD. I miss flying the 172 (flew a 172 exclusively for PPL and IFR training), but I don't miss the rental price
Just found your channel a week or so ago and this is by far my favorite channel on youtube. Keep up the awesome videos! I'm in school now to become an A&P and after that I'm hoping to go on and get my pilots license.
Hey Mr. Aviation! Big fan. I am going to Ft. Hood this summer for training and I should have free time while I am there. I was thinking about flying down to San Marcos to see the Famous 80991. I don't know if you will be back from your trip. It would be awesome to meet a fellow aviator. Also I will be taking my check ride here in Georgia next week. So I will finally be joining the club I have been striving for since I was 15 years old. Keep up the good work and great videos. MrAviation101
Small note regarding the lenticularis clouds: Lenticularis clouds themselves are pretty much harmless. The airflow up there windwards of them is very laminar and its a perfectly smooth ride. (I mean look at the clouds they are sooo smooth) If you have ever flown there you know what I am talking about: 5m/s ~ 1000ft/min laminar airflow pushing you up very softly The real danger lies below them in near the rotor clouds usually in the found in the valleys and also on the side where the air drops down again. You can maybe see one at 8:45 just below the wing tip. Near the rotor clouds you'll find the heavy turbulence and on the leeward side of the lenticularis clouds you'll find massive sink. I've flown underneath small rotor clouds to catch the laminar updraft on the windward side and its not a joke - the turbulence is beyond what I've ever encountered both in passsenger aircraft and in my gliding. I had to hold down a lot of parts in the cockpit that where flying all over the place while the vertical speed indicator was all the way on the lowest stop. I estimate we had about a 1500ft/min sink at maximum, and we lost about a thousand meters (3200ft) in about three minutes. SO look out for those rotor clouds at the altitude you are flying at, those are the really dangerous ones!
JetPackJan : +1 on this comment. Absolutely no turbulence in or around lenticular clouds ! That's the dream of glider pilots ! I've flown hundreds of kilimeters with a wing in those clouds : best time to drink or eat something... However, never pass under them... THERE is the turbulence : in the rotor cloud well below the lenticular ! www.mountain-wave-project.com/images/data/OSTIV_MWP_Wave.jpg
MrAviation101 I did my primary training with an old school army instructor who also was a CFII with 40,000 hours.With your concerns with high density altitude in this video (which is pretty common here in the humid southeast Gulf Coast) I was reminded of the takeoff technique he taught me on a normal takeoff. Because of what he taught me, I do not rotate the airplane on a normal takeoff. I can still hear him telling me to "put the nose in position and let the plane fly when it's ready." I think it's the safest way to execute a normal takeoff. Do you see a problem with that technique and not purposefully rotating (especially near max load)?
Weird question but, how much can you hear out of your headphones? Would you say that they are mostly noise cancelling? Is it important to hear anything other than headphone comms when in a/c like this? Great video by the way as per usual.
Why did you decide to limit flaps to 10 on this approach? Is it because you were flying a long shallow straight in? Or did it have to do with wind/altitude/turbulence/etc?
ugh! so close to meeting you aha. did you land on 26? if so the lake you flew over i fish all the time. Are you planning on landing at bracket (kpoc) at all?
Josh, would you recommend an iPad with Charts and data on board for a Student Pilot flying solo or XC's? I think it would be nice to have as a backup, but I'll also ask my local CFI.
joespeed1952 As a student, take a paper sectional and a paper Nav-log. Bring a second one for backup. I didn't buy a tablet until I was getting ready for Instrument training, and I'm glad I learned all the fundamentals first!
Pretty sure he's from Texas. I've dealt with KDFW intl. airport's atc, they are filled with American pilots and united. Pretty busy and they get ticked off easy. My local airport(Arlington municipal) is a 1 runway made for citation x sized craft is friendly and cooperative. I've had some casual pre flight conversations, very nice people.
Hey josh, I had a question. I'm goin to college next year for flight training and I was wondering if recording and editing takes too much time away from your studies? I was thinking it'd be cool thing to do since I'd be flying so much.
Josh how much does it cost to run a Cessna like yours in the US? I need a comparison because here in switzerland one hour of flying a rented Cessna costs 250 Francs, which is more or less the same in dollars.
40 nautical miles from where you were to big bear? Are the rules different in the states? In Canada you have to file a flight plan or itinerary if going beyond 25nm of your departure aerodrome.
Andy Plater There is no requirement to file a flight plan in VFR conditions under FL180 within the contiguous U.S./ADIZ., day or night, irrespective of distance.
interesting, I wonder why that is, because we definitely DO have to file. www.tc.gc.ca/eng/civilaviation/publications/tp11919-section9-1155.htm see 9.03
Andy Plater If I am flying typically more than about 100nm, I FILE a plan --- but I don't think I've activated one since I completed flight training back in the 60's. I take that back -- I did activate both legs on a flight that I did from San Francisco to Phoenix and back in 1970. Otherwise, I just ask for Flight Following and trust Center and their radar tapes to keep track of me.
Do you have a normal job? How do you manage it to spend that much time in flying? Or are you getting paid for these videos ? Btw great flying! Greetings from Europe ;)
In the US are you legally allowed to enter on a straight in final? Assuming the answer is yes. Only two ways (well, kinda 3) to legally join an uncontrolled circuit here in Canada.
MrAviation101 I wouldn't say there isn't a REG on directions of turns, I would say its subjective depending on who ask. Check out 91.126(B) it seems black and white to me and I have seen Commercial check ride applicants get their very own letter of discontinuance because they do not follow this regulation.
Edgecrusher- TWR I think Josh was answering Travis to say that flying STRAIGHT IN isn't prohibited-- which it isn't. And I've known Commercial applicants who've been failed for breaking this regulation.... I'm guessing that's what you mean, as a LOD is entirely different and isn't given for unsatisfactory performance.
Brandon Maso Yeah my mistake, I was under the impression an LOD was issued for unsat ride, but its exactly the opposite. However, how do you refute 91.126(B) to an FAA examiner or DPE when you landed straight in class G airspace. Granted the regulation allows you an out by saying "or required" which I could most definitely see applies to this particular flight, but lets discuss this generally speaking. As I mentioned before, I have witnessed multiple Commercial applicants bust their ride for entering the airport pattern incorrectly; hence straight in or modified base-final legs. So from an CFI prospective where in the FAR/AIM, A/C, LOI can you show where it says landing straight in is standard procedure?
Edgecrusher- TWR It's allowed because it isn't prohibited! I'll give it you that when teaching a private or commercial applicant around flat-land North Texas/DFW area, I of course teach the standard and recommend procedure... but Josh is not a private applicant who needs instruction on how to correctly enter the pattern, nor were we in Texas. All to often, people (including CFIs, DPEs, ect..) try to pass off their way of doing something as correct, and attempt to justify what they THINK should have been done in a certain circumstance based upon the lack of regulation addressing the matter. In this case, the AIM recommends the standard pattern, and the FAR would address the left turn issue...nowhere in the FAR does it prohibit a straight-in approach, nor does it prohibit entering a pattern on an intermediary leg under this condition. Lack of evidence (such as not having a regulation with regard to entering an augmented or straight-in pattern), is NOT evidence to the contrary!! On a realistic level, I have hundreds of hours and several years of flying around mountains all over the western U.S., and can promise you that there was no other safe way to approach this airport under the conditions. Josh and I talked about the best way to conduct this approach long before getting to this point. If you really want a regulatory citation, though, see 91.3 on the PIC being the "final authority" as to the operation of the aircraft....
MrAviation101 How much would you estimate it costed you to get your private pilots license? I've been thinking about getting mine and have been asking the companies in my area. Using a 172 I have been quoted between 10-12 grand! It seems a bit excessive to me, but was wondering around what it costed you and how many hours in the air it took you.
The training program I'm going through right now through AvCenter in Nampa, ID is about 5,700 for the whole shebang. Very expensive but I'm working two jobs to make it happen, it might take me awhile but I'm committed. Good luck
US1776Patriot What plane is that with? The lowest I've been quoted is between 5,500-6,500. But that would be in a small a22 valor sport plane. Which I'm not to sure I would want to train in.
Josh knows exactly what he is doing with this channel. Absolutely brilliant watching the progress.
Aviation is certainly worth capturing. Didn't expect to find ya here.
Nice seeing ya here
that was one hell of a landing..
Caspian Caesar Righhhtttttt?!?! It was fun.
The sound of that engine on startup at the beginning of the video made me smile a little too hard.
Brandon is A1-OK! I would feel comfortable and relaxed flying with him anytime! He's on the ball and you're lucky to have him with you.
Very cool scenery there, nice safe flying too cannot wait to see the rest of the trip!
At approximately 14:00 you flew over a valley where I lived on a homestead for 12 years. It was great to see as it brought back many memories. Thank you.
his comment about giving you the "allie Look" actually made me laugh out loud.. ^5 thanks for the trip.. waiting for the "teased" takeoff
That landing in that weather really does prove just how skilled of a pilot you are Josh! Thanks for the awesome vid :D
Awesome vid, solid teaser. Can't wait till the new one comes out today. Hope everything is ok at home after the floods...
Maybe it is because I do most of my flying in the mountains; but it looked like a fairly normal landing to me (except for restricting flaps to 10*).
Looking forward to the mystery takeoff
Watching these videos makes me feel like going back to fly small airplanes and enjoy the view from there. Great and very entertaining videos. Good job.
WOWW!! Awesome view and a very unexpected video!
Thank you for sharing these moments!
Just a bit of sand out there.
nice "hook" at the end of the video. I'm looking forward to seeing the take-off. Well done!
You two make for an excellent team!
Nice and turbulent approach ! Good job Josh !
Great video! Beautiful country up there. Nice to see you guys out having fun with flying.
Great that you got to go to Big Bear and too bad you didn't get that crazy landing strip at Catalina. But Big Bear is a great place to fly into!
Nice video, liked the commentating and explaining the steps a lot!
Nice video, great to see the footage from the trip!! :D
So cool to see my local area in one of your videos!
Right?!
Jacob Wilson Same here! So cool to see Josh in our SoCal neighborhood.
Great landing! Looks like you had to fight the airplane a bit.
Great video and nice job flying into a high altitude airport!
Can't wait to do hour building I'll definitely go there!
Nice movie. I like how you analise the situation. Although you state in the start that the movies are not for instruction, for obvious reasons, they can be very instructive. Like this one and the next two movies, the aborted takeoff and the actual takeoff in the next day. Useful lessons there.
Just got yourself another subscriber. I'm a commercial pilot and flight instructor from Brasil.
Man I love your videos! They only are getting better, and it's cool to watch you fly!!!!!
NO WAY!!!! I was born in KPSP and I noticed you made a stop in either KUDD or Jackie cockoran! I'm currently in KSEA but I'm so happy to see you in my old haunts!
Wow that final!!
Thanks for your videos! More in-flight comments on weather, general aviation in general or your decision-making while you're flying would be great !
Watch out we've got a badass over here! Such a sick landing bro!
Great work as always! I suddenly can't wait until Monday... :)
By the way, I landed a couple of weeks ago in my club's 172 P on RWY 18 with the wind blowing 19 gusting to 30 from 220°. It was exciting. My son, who is post solo in his primary training was very impressed. I was just glad to be on the ground.

Safe Landings,

Great job...!!

Very nice!
Stupid Mondays,,,, Why must I wait on you.....
great.. Now we have to wait for the take off... Y u do dis?? XD
Awesome video Josh. I noticed your iPad yoke mount. What brand is it and do you like it?
Thx Bob.
Josh, great landing!! Having only flown a Piper Cherokee, why do you choose to use only 10 degrees of flaps on landing the Cessna?
MrAviation101 what settings do you use for your gopro's? Everything looks great!

2 videos in one week!! What ?!?!?!
what did you use to connect your audio recorder to your headsets/atc?
How dare you tease us by not uploading the takeoff lol. Good job.
Is that a gold toe T-shirt in the debrief section josh??
Weird question but, how much can you hear out of your headphones? Would you say that they are mostly noise cancelling? Is it important to hear anything other than headphone comms when in a/c like this? Great video by the way as per usual.
Why did you decide to limit flaps to 10 on this approach? Is it because you were flying a long shallow straight in? Or did it have to do with wind/altitude/turbulence/etc?
Why is it so gusty? Summer instability?
Now try it with some crosswinds. :)
What engine instrument did you install into N80991?
ugh! so close to meeting you aha. did you land on 26? if so the lake you flew over i fish all the time. Are you planning on landing at bracket (kpoc) at all?
I live seven minutes from bracket!!!
Yes KPOC Brackett! They have a nice diner too
sweet! I'm in rancho about 15 minutes from kpoc do you have a share aviation account? Jacob Hardy
Not yet. As you can see in the pic I'm kinda young. I will get one though
I do now! Already friends with mr aviation-josh
Josh, would you recommend an iPad with Charts and data on board for a Student Pilot flying solo or XC's? I think it would be nice to have as a backup, but I'll also ask my local CFI.

How do you like socal ATC? I think they're the best, nothing like the east coast, not sure about where you're from.
Pretty sure he's from Texas. I've dealt with KDFW intl. airport's atc, they are filled with American pilots and united. Pretty busy and they get ticked off easy.

How do you know which radio station you have to contact?
Did You See San Bernardino Ca
Is it hard to pass the light gun test?
Excuse my randomness... Does your plane have air conditioning?
How do you afford flying at the rate you do?
I am a new student pilot and just wondering why on landing it was max 10 degrees of flaps?
Gusty winds and turbulence
hey Josh why are u flying with instructor?
Marian FD He's a good friend, and proficiency flying never hurt anyone!
+MrAviation101 oh, great! Its nice flying with friends. PD: Great flying!
40 nautical miles from where you were to big bear? Are the rules different in the states? In Canada you have to file a flight plan or itinerary if going beyond 25nm of your departure aerodrome.

see 9.03
Andy Plater Yeah I was thinking the same thing, but you never know what you'll get in the US
Andy Plater If I am flying typically more than about 100nm, I FILE a plan --- but I don't think I've activated one since I completed flight training back in the 60's. I take that back -- I did activate both legs on a flight that I did from San Francisco to Phoenix and back in 1970. Otherwise, I just ask for Flight Following and trust Center and their radar tapes to keep track of me.
Gwen Walcott I rarely ever file a VFR flight plan. I'll usually get flight following if I'm going more than 100 miles from the airport
Do you have a normal job? How do you manage it to spend that much time in flying? Or are you getting paid for these videos ? Btw great flying!
Greetings from Europe ;)
In the US are you legally allowed to enter on a straight in final? Assuming the answer is yes. Only two ways (well, kinda 3) to legally join an uncontrolled circuit here in Canada.
Travis McCurdy Yes. It's not recommended, but no regulations prohibit it. At this airport, that's the only way to land without hitting a mountain!
MrAviation101 I wouldn't say there isn't a REG on directions of turns, I would say its subjective depending on who ask. Check out 91.126(B) it seems black and white to me and I have seen Commercial check ride applicants get their very own letter of discontinuance because they do not follow this regulation.
Edgecrusher- TWR I think Josh was answering Travis to say that flying STRAIGHT IN isn't prohibited-- which it isn't. And I've known Commercial applicants who've been failed for breaking this regulation.... I'm guessing that's what you mean, as a LOD is entirely different and isn't given for unsatisfactory performance.
Brandon Maso Yeah my mistake, I was under the impression an LOD was issued for unsat ride, but its exactly the opposite. However, how do you refute 91.126(B) to an FAA examiner or DPE when you landed straight in class G airspace. Granted the regulation allows you an out by saying "or required" which I could most definitely see applies to this particular flight, but lets discuss this generally speaking. As I mentioned before, I have witnessed multiple Commercial applicants bust their ride for entering the airport pattern incorrectly; hence straight in or modified base-final legs. So from an CFI prospective where in the FAR/AIM, A/C, LOI can you show where it says landing straight in is standard procedure?
Edgecrusher- TWR It's allowed because it isn't prohibited! I'll give it you that when teaching a private or commercial applicant around flat-land North Texas/DFW area, I of course teach the standard and recommend procedure... but Josh is not a private applicant who needs instruction on how to correctly enter the pattern, nor were we in Texas.

If you really want a regulatory citation, though, see 91.3 on the PIC being the "final authority" as to the operation of the aircraft....
MrAviation101 How much would you estimate it costed you to get your private pilots license? I've been thinking about getting mine and have been asking the companies in my area. Using a 172 I have been quoted between 10-12 grand! It seems a bit excessive to me, but was wondering around what it costed you and how many hours in the air it took you.
The training program I'm going through right now through AvCenter in Nampa, ID is about 5,700 for the whole shebang. Very expensive but I'm working two jobs to make it happen, it might take me awhile but I'm committed. Good luck
US1776Patriot What plane is that with? The lowest I've been quoted is between 5,500-6,500. But that would be in a small a22 valor sport plane. Which I'm not to sure I would want to train in.
the_real_matt Yes that is including the airplane and it's in a Cessna 172 Skyhawk II. Great little airplane to learn on.
US1776Patriot How did you get them to give you such low of a price?
It's a small little airport I think that's why.
d video
