My CFI demos the "impossible" turn and shows why he wants to rebrand it as the "improbable" turn.
*This is not intended as instruction! This is a great topic to ask your CFI about, have them demo and go over all of the risks involved.*

There's one MAJOR problem here though. He cuts power and begins turning at the exact same moment. Ignoring the half-second or so that humans take to react to literally anything, if you have an engine failure on takeoff, you're gonna have a solid couple seconds of nearly stalling before you figure out what just happened and push the nose down. Then on top of that, you need to consider a second or two to think "OK, where am I putting this?" and decide if you're going forward or turning around. That's why people so often quote 1000 feet AGL as the cutoff...to factor in the reaction/decision time. Let alone that no one is going to fly perfectly in an emergency.

That is why you do take off briefings, to be primed to react. Say to yourself, _"The engine is going to fail on this takeoff, what is my plan...."_ *Every. Single. Time.* Sample take-off briefing: "Taking off from RWY24, climbing straight out to 2000. Winds are 290° at 7. We'll accelerate to Vr, rotate, 10° nose up Vy. Engine failure or abnormality prior to rotation: close throttle and come to a complete stop. Engine failure after lift off and there is runway available? close throttle and land on remaining runway. Engine failure before 500 agl, landing straight ahead. Above 500 agl, immediate 45° bank R turn (into the wind) back to the runway, glide speed" Like an athlete visualizing a sequence of complex actions prior to performing them. All the decisions are already made, now you execute.

As said previously, all those decisions must be made BEFORE you take off. If it's your home field, you should already know where you're going to put the airplane if you have an engine failure. You brief it as part of the pre-takeoff checklist. "if engine out with usable runway set it back down, before 500 ft I'm going to farmer Joe's field, after 500 I'm turning back" etc. Then call out those decision points when they happen. Professional pilots do this every single time. It is literally part of the checklist. That's what the V1, and V2 speeds are.

An instructor that not only shows his student about emergencies but methodically plans to fly from SNA to F70 to show him “ the impossible turn “ being very possible, is an instructor that’s incredibly hard to find and worth every penny. Both of them acknowledged that a 3 sec Cap’n Sully “ Oh butt-poop” pause was needed before starting the turn but the biggest lesson is the necessary up to 60 degree bank required to quickly make the turn. Most instructors refuse to demonstrate this maneuver, and I’m not too sure if it’s because of certain flight school policies, insurance or themselves I’m just wondering what time of day did they perform this maneuver because F70 gets pretty busy.

All pilots should know "A Possible Turnback" from An Impossible Turnback". I have a formula for small singles Turnback Maneuver. The 777 Turnback Rule. I taught aerobatics and 2 kinds of turnbacks in my 1990's CFI years. 4 kinds of EFATO and partial power too. For heavier singles i have The 999 Turnback Rule for heavier singles. Use this formula i used about a hundred times to teach EFATO Turnbacks when CFI. It works well. I have 3 engine fails on take off on Cherokee 180 and all i landed back with no damages ever. FOR TOTAL ENGINE FAIL Use the 777 EFATO Turnback Rule for light singles. The 999 rule is for heavy singles. The 777 rule can be done even when on preflight or driving to airport. Will I be able to climb over 700 fpm? Yes? Are the winds over 7 knots? Yes? Then mark the altimeter to 700 agl for EFATO turnback. THE 777 TURNBACK RULE NO POWER- FOR LIGHT SINGLES. Between me and my 1990's students we had to do 4 turnbacks due bird strikes, loose engine cowls an engine problems on take off. 4 airplanes saved i know. iGNORANCE of Turnback is not the solution, IGNORANCE is the problem.

It also depends on the aircraft you are flying. In a glider taking off behind a towplane, if the rope breaks or the towplane engine fails and I’m above 200 ft AGL, I will turn back to the runway and have plenty of time and altitude to line it up and land. In a 150 hp Citabria, if the engine fails above 500 ft AGL I have lots of altitude to turn back and probably will need a slip to get it down on the first half of the runway. In the Columbia 350 I fly, nah, I ain’t turning back unless I’m already on crosswind or downwind when the engine fails. It has the same rate of climb in fpm as the Citabria, but it is going a lot faster so the climb-out angle is much shallower and you are much farther away from the airport at 500 ft AGL and 1000 ft AGL unless you are staying in the pattern or departing on a downwind.

The main thing here is that over the opposite threshlod you had already like 1300-1500 ft, aiming for 1800ft AMSL and 500ft AG. There were plenty of runway left and you have been climbing already. It would be much better to simulate short runway by keeping the plane down at ~50kts till the last 600-1000ft of the runway. GA is about using short strips very often :)

I don't know what your speed was when the simulated engine out happened. The take off seemed to be designed to set up low AOA rather than best climb. How would it have worked if you were doing 75 knots at the time of the engine power cut off? As for Sully turning on the APU in 3 seconds... Maybe that was a natural reaction to no juice on a glass cockpit aircraft? The big birds flip between between APU and main engine generators every flight.

I would add, we also REALLY need to know the airport and surrounding areas. Better know if there's suitable emergency 'off airport' landing space off each runway or not. Otherwise, you burn precious seconds trying to find a landing spot when you could've turned back (maybe). My CFI used to drill that into me and now I always do the 'if engine fails, here's where I'm going' verbally as I'm lining up for takeoff. I hope to never need it but maybe it'll save my life one day.

The engine quitting at the exact right time is super duper unlikely. When your engine quits, you don't check altimeter first. If you're a hundred feet low, this is again impossible. If it quits a bit later you might be higher but also further away and especially if you've not climbed all the time you again can't make it back. What they're doing is laboratory conditions, so it's still the imposaible turn.

Yes, which is why this is a 1. A controlled demonstration and 2. Important to brief what you're plan is at ever given altitude on takeoff. Example, "below 500' we're landing straight ahead. Above 500' we're turning back." You're checking those pre-planned altitudes as you get to them. Not when the engine quits. I would recommend working with your CFI to practice a takeoff safety briefing and have a plan in place to make an engine-out on takeoff more like a laboratory and less like a surprise.

In real life you will not have the luxury of choosing when your engine fails. It will hit and surprise you. Hes got over 1000 flights.

Excellent. Being aware of the loaded wing consequences is critical to avoiing the four regimes of flight: Stall. SPIN. Crash. And, Burn. Gallows humor. I'm glad that you are weighing in on this old school stuff, and how you teach it. I was taught by Bill Sellars on my CFI. He flew P-39s and P-63s in the Pacific. Lots of low level stuff.

@@dickjohnson4268 Another USA training fault is with GRM. They teach GRM at high altitude, and high speed mostly (Mild Maneuvering GRM). I learned GRM in a 1969 tough school. Did at 16 years old a slow Piper Colt, at 500 feet only and with hard winds too (That is Hard GRM). Mild GRM makes mild pilots. Mild Maneuvering pilots crash when things get hard like low GRM, low hard emergencies or low go arounds or hard winds maneuvering needed.

@@feetgoaroundfullflapsC Yup. Fat wing Pipers are still a good teacher. When checking out new Bone pilots, a lot of them are really shy about extreme handling. The aggravated stall (cross controlled and in particular, the V birds) have them looking at the ground, and really gets their attention.

He knew the exact moment the engine was going to fail, at which altitude, he had already planned a return course to the runway, knew the area well, and above all knew that he had power available should he need it. He probably practiced many times and this one was the one in which he didn't have to add power and go around. Anyone can do that. That is a a very possible turn - and bad advice.

Of course, it was a planned demo of the maneuver need to be executed in the event this happens. All of which is discussed in the video. Demonstrating a maneuver like this, it's critical do it in a controlled environment and manor by something with lots of experience. And not everyone can do this which is why it's so important to pre-brief before every takeoff and have your planned course to return to the runway if you're at the altitude you've briefed will be your attempt-to-return altitude. I highly suggest getting with your CFI to discuss how to pre-brief your departures to be prepared if/when you do loose an engine (partially - which is most engine "failures" or full). That conversation and possible demonstration by your CFI could save your and and your passengers lives one day.

This is the truth, but not the whole truth, and that makes it dangerous. It is dangerous to show this to people without putting emphasis on the few facts that are all but ignored here. One is that this is not an engine failure, and the other is that this is done on a comfortably long runway. Try doing that with an ACTUAL engine failure, not with an idling engine. With your prop working as an air brake. And then try doing it on a runway that does not extend another one or two thousand feet beyond your take-off point. And then tell people that you did the impossible turn.

Trying that would make it not a demonstration and just an, as you put it, ACTUAL engine failure which is ACTUALLY dangerous. What's been explained and demonstrated here is the maneuver where a return to the runway would be possible and how aggressive it has to be. The reason this was able to be demonstrated was because it was a longer runway in controlled conditions. Actually shutting the engine off in a single-engine plane for demo/learning reasons is "non-starter"-pun intended. Hopefully you were able to see through the obvious controlled aspects of this demonstration, watched the entire video and listened to comments of a very experienced CFI. Cheers.

You would use less runway, have less aggressive bank (and less risk of stall/spin) if you dont immediately drop the nose. Climb out in a 172 is 75kts, best glide 65. If you pitch up at failure to achieve glide speed while turning you will have better energy management. The nose passes through the sky like a lazy eight.

maintaining Vy climb attitude following the engine failure, the speed will rapidly fall to 65, likely before you even process what's going on

@@GZA036 if speed bleeds off before you even know what's going on then it would be impossible to continue climb at Vy, yes. But if you recognize what's going on and have excess speed above glide speed why not trade it for altitude?! I fly a navion, climb out at 110 to 120, best glide is 80. my first instinct is to pitch up. Once the engine quits altitude is life. Practicing the same in a 172 pitching up to slow vs banking and diving...every time I pitch up I'm over the runway with altitude to spare. Every time we push the nose over and pull hard we end up short of the runway

Please read the disclaimer in the description. This is being demonstrated by an ATP/CFII with 800+ hours in type. It would be irresponsible not to have this discussion with your CFI and have them demonstrate how it's done properly and safely and how to brief it before each takeoff. If you are a pilot and would never consider it, for your safety you should have that conversation with your CFI. It may save your life someday.
