The Turn

Success Factors for a turn back

For each second of delay, the aircraft is more than 100 ft further away and loses more altitude.

Return path length and altitude loss are substantially greater for turns less than 210 degrees.

Goal is to maintain "Best Glide" to the ground. Fighting the natural tendency to pull back as ground approaches.

" I learned a good deal about the viability of such turns during my instruction with George, but this greatly enhanced my understanding. "

" As a very old former ATP and CFI, I recreated experiences and assumptions made in previous flights from three locations!!! Wish it had been available at the time in the mid 80s - 90s when I was flying everywhere with my wife working in 15 different States, to meetings, vacations, etc- "

Why does the bank angle in the primary turn change with aircraft?

One of those things was that every aircraft has a bank angle that ensures an acceptable safety factor from the possibility of an accelerated stall, while still giving a reasonable option to return to the runway. Why are they not the same value for every aircraft?
