    One thing that I just started doing was attempting the impossible turn in a real airplane to determine a bunch of different scenarios in which I might make it. And one thing I've identified, on days where my climb performance is poor and low or calm winds, I need to be at 1200 feet AGL before attempting to turn back b/c I won't make it at 1000 feet. Which is something I can add to the takeoff briefing:
    ... since today is hot and we're pretty heavy and winds are calm, if I have an issue above 1200 only then will I turn back and land on this runway.
    Where as on a cool day with a 10kt headwind
    ... since today is cool and we have a 10 kt headwind, if I have an issue above 1000 feet only then will I turn back and land on this runway
    etc, etc. The thought just struck me right now that since I'm on the ground, I could write these scenarios down into a table and check that as part of my takeoff briefing. 🤔🤔

    contrary to popular beliefs, you actually have to pitch down to "stretch" the glide distance

  • @NRB-mb7jc
    @NRB-mb7jc ปีที่แล้ว +1

    Try your sim again, but instead of using standard rate, put the plane immediately up on edge and give up that energy to complete the turn faster. As fast as possible, the steepest you can take it without loss of control. This may reduce the distance to the runway after the turn is completed. See if you make it back that way. I have tried this in practice and it works.

    This reminds me of the best move to make a CFI equal parts dissapointed and proud at the same time. Practicing power off 180's, "misjudge" the glide so you come in just a hair short of the runway then just as you're about to enter ground effect add a notch of flaps. You get the bonus lift without the full drag penalty and float the extra 50-100 feet. 🤣
    Also don't actually try this... but remember it does work if you're every juuust shy of making your point.

    My CFI and I practiced this and it's a little bit more reliable depending on the aircraft. We still brief every time that below 800' AGL, we're landing straight ahead, but above that, we can do it almost every time. The trick is to fly a plane like the Remos G3-600. It has a glide ratio double that of the Cessna 152/172 which allows us to pull this off. I can't imagine trying it in a Cessna. Great video!

  • @TiagoSeiler

  • @triboarder06
    @triboarder06 ปีที่แล้ว +1

    Would be interesting to see a few more scenarios like 60 degree turn, letting the nose drop so the wing isn't loaded, maintaining close to optimal glide speed and see where you end up. I think in some instances you'll make it, others no but most gentle banks turns you won't have a chance. Landing straight ahead in most cases will still be best option. Great video as always!

    "And though I've never experienced a total loss of power on take-off, I've had enough partial issues at low altitude..."
    Excellent topic! I experienced this exact situation about a year and a half ago in my Skyhawk - 120fpm on climb out, things just didn't feel right. Fortunately, I remained calm (a lot calmer than I thought I'd be) and almost immediately discovered an improperly set throttle friction lock. Problem resolved immediately. Finally, my takeoff briefing includes mentioning by the name of the road I'll be taking in a full loss of power situation whilst departing 30 - Canby Ave. Basically no power lines anywhere, relatively smooth gravel road and hardly used by cars.

  • @christophvz
    @christophvz ปีที่แล้ว

    Excellent video as always. One thing I always accentuate with my students is that the biggest risks in loss of thrust scenarios is 1) loss of control and 2) hurting someone on the ground, not our safe landing per se. One typically only needs about 30 ft of distance to stop and survive the 9G crash (as per FAA Flying Handbook Chapter 17: Emergency Procedures). So practically speaking, any field is “suitable” as long as we put the plane at wings level attitude and normal landing speed. I typically recommend an open field, a runway, a road, a beach, dense trees, or water, in that order. Runway is the second best option in my opinion (unless we are in a tight traffic pattern already or in a high overhead position) because it will make it extremely difficult to consider other options. During engine out situation we constantly have to re-evaluate our options based on perceived angular distance; once we notice the original plan is not working out, we just got to pick a different spot. Briefing our options for the field we are about to take off is our best risk mitigation strategy; google maps with satellite view is a great tool to survey those options.

    I used to rent a Cessna from a flight instructor who insisted that all his students and renters learn the runway turnback. So we did the lesson during the owner/operator checkout flight. No simulated turnback at 2000 agl or anything like that. We flew the actual maneuver, all the way back to the actual runway with power off and actually touched down to a full stop three or four times. Below 300 agl land straigh ahead, 300-500 agl 45 degrees left or right of centerline, and we did all of our maneuvers for the real turnback at 500 agl. This is in a Cessna 172 with 2 souls. This was back in 2010 I don't recall the exact weather but it was not particularly favorable or not favorable. We did this at KHZR near Baton Rouge, LA using RWY 35 so plenty of trees and then the river. Cessna N4733D if my memory is good. Its a frisky few seconds I will admit......the stall horn chirps basically the entire time but the turn is FAR from impossible. My biggest take away here is that I agree it is all about conditions and pre-takeoff planning. The problem I have is with this whole 3 second brain mush rule everyone seems to want to put in to the maneuver. Its a solvable problem as long as you solve it on the ground, just before takeoff. Because of this lesson, I always assume my engine will quit some point below 1000 agl so I "spring load" myself to react to it. Another important lesson I think is that you need to be proficient enough not only to perform the maneuver, but also to make the decision whether or not to. In Louisiana, density altitude plays a large role on performance in the summer. I do wish we could change the name of the maneuver to something a little less controversial like just the runway turn-back. As pilots, we should not color the terminology in a particular way. If instructors don't believe in the maneuver, they should be upfront about that and explain why instead of preparing scenarios where only the worst situations are present. Do a simulation where you don't wait 3 seconds because you were already prepared for an engine failure. Do it with neutral weather and temp conditions....then do one with favorable conditions. Do them all and show people all of the scenarios. Educate.

    • @xvxchronoxvx
      @xvxchronoxvx ปีที่แล้ว

      Also I appreciate a "true simulation" rather than watching certain other youtube flight "instructors" who do it up at 2500 agl where the aircraft already takes a performance hit due to altitude and there's no ground effect which basically means you will lose every time. Makes it easier to make your point if you're rigging the demonstration whether you mean to or not.

    I learned 4 kinds of EFATO in 1996 from the only expert in New England on EFATO. Or the USA an examiner told me twice. The main points are. For a power off Turnback; Dont turnback if climbed under 700 fpm or are under 700 agl. Dont. PARTIAL POWER? Dont turback if under 300 agl climbing under 300 fpm. Those are the 2 more simple rules we came up 20 years ago. My CFI Cherokee 150 hp had a Blue Line on Vglide speed and he set altitude marker on the altimeter too.

    Some airports have fuck-all ahead for emergency landings. For your best chance. You'll need:
    1) Aircraft with respectable glide ratio and climb angle/rate
    2) Strong headwind component (compared to best-glide speed) on takeoff
    3) Climb at Vx until engine failure
    4) Turn into crosswind component, immediately upon engine failure
    5) Hold best-glide speed and AoA below stall during turn (stall horn intermittent, at most)
    6) Reduce glide speed and/or select flap setting depending on the strength of the tailwind.

  • @braininavatnow9197

    Fortunately this can be practiced in the air. Part of the briefing is to know the minimum safe altitude where one can safely turn back (obviously this is dependent upon conditions and aircraft).
    I just assume that the engine is going to crap out at the worst possible time and plan as best I can.
    Truth is there are times in urban areas, over mountains, over cold water etc. where you're probably going to die, just as there are times in driving when if something bad happens you are going to crash but at least I'm aware of it and prepared psychologically to deal with it as best I can.
    Of course the best is simply to stay away from places where you can't make a "walk away" landing with a total power failure and it's not really that hard.
    I think the NTSB says that 50% of propulsion loss forced landings in GA aircraft are fatal.

    I did this in real life at an uncontrolled airport with another pilot and we were able to turn back and land on the opposite runway from 400 AGL in a Grumman Tiger. We threw it into a steep bank and kept the nose down and didn't have much trouble. We were 2 people and fuel to the tabs. Wouldnt try it at max gross unless I had more altitude.

    At 500 ft can be totally accomplished
    If flaps are properly managed and ignoring the runway shoot for the taxiway. Or other flat area on the airfields a former Alaskan bush pilot.Before every take off.always select a position on the field or off the field where you are going to head in the event of engine failure.This takes the guesswork out of it.
    An impossible turn back towards the runway should never be attempted below 500 AGL head for your selected crash site and stick with the plan.

    I was trained from day one by my PPL to always do a take-off briefing.
    We also practiced power loss during departure climbs when my CFII would suddenly chopp the throttle (at an appropriate training altitude).
    I'd then immediately pitch forward HARD, pull the flap bar to full out (to prevent a stall) and perform a high-bank turn into the wind. The best I could do during training was lose only 500 feet as I then brought the flaps in slowly to maximize glide. This was in an Archer II.
    So I learned that if you're not at least 750 ft AGL, there's not enough time or glide distance to even consider it. If I were above pattern altitude (1007 ft AGL), I'd just do a short field landing in the pattern.
    Otherwise, land straight ahead and prepare for off-field landing as the checklist stipulates.

      @@Virtualmix Because pulling the flaps out LOWERS stall speed. If you're going to do a steep turn low to the ground, you do NOT want to stall. So you pull the flap lever (on an Archer II) to extend flaps full since you're already climbing at Vy or Vx. Then after the steep turn you retract the flaps appropriately for your airspeed.
      We practiced this with and without flaps and with full flaps I could turn 180deg+ and lose the least amount of altitude with the steepest bank angle.
      Again, this was just to demonstrate the concept and how sharp your stick and rudder skills are to pull this off and when it was simply not an option.
      This is why we train. To understand what we and our aircraft can and cannot do.

    It's easier to aim somewhere close and find a creative way to drop altitude, than it is to aim somewhere far away and invent energy you don't have using sheer force of will :D Also I don't know how it works in fixed-wing but in helicopter land slowing down to "stretch the glide" is a shit idea. There is one speed / configuration that gets best glide: that's it. Slowing down just gives you a momentary relief of sink rate in exchange for increased angle of descent for the entire rest of the approach. If you think you need more distance, pitch for best glide speed straight away (and do whatever other stuff you do in an airplane idk) and then maintainnnnnnnnn it all the way to ground effect if you have to. Slowing down just makes you shorter.

    The video Richard narrated gives some sort of false hope that The Impossible Turn can be accomplished by some types of aircraft and under experienced pilotage. However reality proved otherwise...this was a highly trained pilot and he was flying an aircraft comparable to a Cessna 172.
