Engine Failure After Takeoff

- This video describes the results of my father's decades-long research into the subject of turning back towards the runway after experiencing an engine failure shortly after takeoff in a single-engine airplane. I discuss techniques for determining when it is safe to do so, and how to practice the maneuver and become proficient at it.
Until recently, conventional training and wisdom dictated that pilots should always land straight ahead when confronted by an engine failure that occurs shortly after takeoff in a Single Engine Airplane.
This controversial topic has been hotly debated since the early days of aviation to the point where turning around to land on the departure runway has been called “the impossible turn.” It can be argued convincingly, however, that there are instances when it would be safer to return to the airport than to land straight ahead following such an engine failure.
The FAA now states matter-of-factly in Advisory Circular 61-83J that “flight instructors should demonstrate and teach trainees when and how to make a safe 180-degree turnback to the field after an engine failure.”
Brian Schiff will discuss the principles involved in returning to the airport safely. It will be based to a large extent on his father, Barry Schiff’s, decades of study and research involving this subject.

Better practice first The Flyover Teardrop Turnback. At level flight at Vglide speed and 1,000 agl, fly over a highway, pick an easy to see spot, fly over it, then do a Teardrop Turn to fly over again in opposite direction. Then do a teardrop again. Do 3 plus until you do them very well. Then fly over doing a Hook Turnback instead of a Teardrop Turnback. Do a few Fly Over Tunrbacks Teardrop then Hook Turnback kinds. That way you will understand Turnbacks better BEFORE doing them at airport.
On your tittle you put shortly after take off. NG., it is Turnback after a safe angle climb and safe altitude to start The Safe Turnback to nearest runway. Please change that, Brian. Shortly after take off can be 100 or 200 agl. An impossible turnback instead.
Turnbacks are turns 180 degrees plus. Turnbacks finish more or less on the spot you started them. Not just a heading change like an 180 is. It Is a track reversal, not just an Uturn or heading reversal 180. You need to know how to do Turnbacks not only on climb emergencies, but also on Flyover Turnbacks, Box Canyon Turnbacks, Circling Approaches Turnbacks and Overhead Entries Teadrop Turnbacks too. Many pilots dont know them well and crash on the above 5 maneuvers. Even ATP's have crashed on above 2 kinds of Turnbacks. Shame.
I learned Turnbacks 2 kinds from emergencyLowManeuvering channel CFI, but that was i think in 1997. We did them level first over a road simulating a runway below. Did turnback teardrop and also the ? shaped kind. He called them GRM Flyover Turnbacks. Thousands of stalls have happened because the pilot didnt know GRM Turnbacks, even ATP pilots dont know them- most of them. Good to do GRM Turnbacks first, then EFATO Turnbacks later on. Box Cannyon Turnbacks also before the EFATO Turnbacks. So there are 2-3 kinds of turnbacks and 3 places were you might need to do them, not only on EFATO.
It is a Hook Turnback. Hook Shaped or question mark shaped. Like this shape ? That is Not a 360. Doing 360's wont let you practice the final alignment of the Hook shaped Turnback. Draw them. They are very different maneuvers a 360 from a ? or Hook Turnback. like this shape ?
It is not a 360 it is like a Hook Shaped or Question Mark Shaped turn. A Hook Turnback. around 270 degrees total degrees of turn, never 360 degrees. I learned it in 1996 and used to teach them from 700 agl on cherokees and cessnas..
Power on Turnbacks you do them mostly Teardrop Turn. No power you do them Hook Turnback to land, which are quickers. But at Vglide or more. From ELM Channel CFI i have done them on Circle to land turnbacks, GRM Turnbacks, LOTOT Teardrop Turnbacks at Vglide speed, Box Canyon Turnbacks and on overhead entries too. About 5 places you can do them Teardrop mostly or Hook Turnback and many do them every dam day. Like Crop Dusters LOL, And Dan Gryder says "You dont know to learn those hard turns. And what about Fighter Pilots and A-10 pilots doint Turnbacks every practice?.. LOL. DG is Anti turning. Poor Guy.. HeSucks at Vglide Turns.. LOL..
My crusty old CFI taught me to make all landings as 180 power-off landings. That is how he flew all five of his airplanes (he was the airport manager, A&P, CFI, charter pilot and DE) and he always said that shock cooling was a myth and that was the main reason given for doing wide patterns under power. I always flew my 182 that way and knew very well its gliding capabilities as every landing, other than instrument approaches to large airports, was made that way. And I never had any “shock cooling” engine issues.
I greatly appreciate this well done discussion on turning back to your takeoff runway!!!!! The Best I ever seen one the subject. Keep up the wonderful work.
Brian that was fantastic. Well done. This is something I have practiced with my instructor, as should every single-engine pilot, so the maneuvers that you suggested are very familiar to me. Kudos for pointing out to your viewers the importance of training in this area, the “non-impossibility” of the maneuver, and the numerous factors that need to be addressed in order to maximize the chances of success in the turn back maneuver. Also your repeated insistence that if there is a safe alternative ahead, don’t turn. My great hope is that you have inspired many pilots to do the training that is required to obtain and keep proficiency in the turn back maneuver. I know for sure that you have inspired me to practice it again and again.
My CFI showed me a video of him doing zero power turnbacks many times with up to 16 knots winds. From only 600 agl on his cherokee 160 hp. He cut the mixture just after turning, then an over Vglide forward slip to the numbers on 4k runway (A Fast Forward Slip) then he cut the flaps in the flare to cut the lift. With no mixture/no flaps stopped on 3,500 of runway 4 times on that 1995 video in Florida.
Make it simple. Dont turnback if runway is less than say 3,000 feet long, especially if windy. Unless an LSA. If over, practice, but first put a blue line marker on ASI for Vglide easy to see., and an altitude marker for altimeter to mark the minimum alt to turnback with some power (400 agl), and double that if no power on engine,
The Turnback to other runways makes you practice real pilot task. You can also apply that practice to Flyover Turnbacks, and Box Canyon Turnbacks. 3 places were knowing turnbacks can save you from an accident. I learned them in 1995 from the other commenter on AirplaneEmergencyTurnbacks channel and had to do one that saved my life. He taught that maneuver to his students and 2 of them had to do them later on.
Always an excellent topic !
I like the comparison of Vx vs Vy takeoffs. I have heard many instructors recommending Vx always for greater height but I was always concerned about it because the speed is lower than Vg and the large pitch change that would be immediately required. I concluded for myself, and other reading, that Vy is safer for normal operations.
I had to do it twice, and know about 4 that had to do Turnbacks to opposite runway and brought it back. Only one bent a landing gear. We are the majority, but because we didnt have cameras and didnt crash, the "The always crash in front Guys" don't want to count us. That is Their Fault, THEIR FAULT, not ours.
Barrry and Brian Schiff, Here is the First ever video or film showing emergencies on take off 4 kinds and finishing them all on runway. And with strong winds crosswind/tailwind landings too.
Reduction of power ON TAKE OFF KINDS; the ROTOT OR Lost of power LOTOT. also called. I like to use ROTOT lately.
very good
Excellent presentation! Well thought out and presented.
