The Impossible Turn with

- Whether it's possible or impossible, the runway turnback should carry this disclaimer: “possibly misunderstood”. Join Brian Schiff and Russ Still for a deep dive into the myths and misconceptions of this contentious topic. Pilots frequently boil it down to a simple stick-and-rudder maneuver, but this leaves many dangerous holes in a pilot’s ability to properly respond. Learn what some of these pitfalls are in this livestream from Thursday, April 21. #FlyGoldSeal #NAFI #FlightTraining
Great discussion, lots to think about.
Better practice first over a mile long or less highway section with some headwind or better, WITH A CROSSWIND ON IT, . Simulation a runway at 1, 000 feet agl over that highway section, them sim a take off from it, climb at Vy, say at 1,800 agl, power idle, nose down, 45 degr bank at slightly under Vglide. Flaps, align early to the 1k agl sim runway. If a crosswind, AFTER go around, CLIMB AGAIN to 1,880 agl and Turnback to the wind again, never tailwind turnback. Repeat. Those are callet 270 Turnbacks to opposite runway.
Well that's easy! Salina, KS has a 12,301 foot runway!! Engine problems you are still able to land straight ahead!
Only a panicky pilot will take 4 seconds to push nose down and turn.
I practice the maneuver at altitude to identify minimum required altitude and cement good procedural habits. The time to discover what's required isn't during an actual emergency. After practice in a PA28-180 I was able to make a 210 deg turn to get pointed toward the runway with 300'-350' of altitude loss, including an intentional 4 second delay after power loss to simulate "What the heck just happened?" Given that knowledge I identified 700' as my minimum altitude to make a turnback in that airframe and then practiced at the field. I found I was actually a bit high when returning to the runway coming back from that altitude.
Since our community loves acronyms, how about, EDDA, the Emergency Departure Decision Height? All based on your particular POH, of course. :)
Glider pilots learn to make the "impossible turn" from 200' agl. Given, gliders have a lower sink rate and a better L/D, but there is some combination of factors that will allow a safe return to the runway. Every aircraft is different and every flight is different.
Some call a turnaround the airport accident as "Another Turnback crash". That is BS from the ones ignorants on Turnbacks. On the turnback maneuver you dont turn around the airport or anything. Just turnback to the runway closer to you. Many crashes are a Turnaround, NOT A TURNBACK.
Dangerous and incomplete discussion! I expected you to pull out a slide rule. You sounded woke and sudo intellectual!
