Practicing the "Impossible Turn"

Hello POA,

A few months ago I started a paid apprenticeship at a local flying club for my A&P.
Its a fleet of of 14 aircraft. Mooneys, 152s, 172s and Piper Warriors.
I've been checked out in all of the planes except the Mooney, but I'm reaching the hour requirement so I'll do that soon.
Anyways, the nature of my job includes test flying the planes after we've done repairs.. flying them when they get squawked (just yesterday we had a high oil temp squawk on a piper, had to fly it around a bit and ended up changing the thermostatic bypass valve).
My boss, A&P IA and fellow pilot asked my instructor to nail emergency procedures down.
We went up in a 172 yesterday for 1.7hrs and just did emergency procedures the whole time.
Towards the end of the flight we went up to 3k and practiced departure engine out at altitude.. we climbed to 3500ft, pulled power and made a 180. 70kt, 45 degree bank and NO STALL HORN. We did that 5 times and each time I was able to complete the turn with 120-150ft to spare.
We then went down for a full stop, taxied back and he said to just do a normal takeoff and we will do a few soft field landings and call it a day(lies lol). At exactly 500ft AGL, he pulled the power and said "your time to shine". I leveled the nose and immediately began a 45* bank right turn into the wind (runway 21, wind was 230@9) kept it between 67kt-75kt. Again, I was able to complete the turn with about 120-150ft to spare. The hardest part of this whole procedure was landing with a 8ish knot tail wind. Greased the landing but I took up way more runway than I had expected. Left flaps up due to the tailwind.
There was absolutely zero traffic in the pattern or around the area.

This was probably the coolest thing I have done training wise. I wish we could have done it more than once but I understand this isnt something you want to be doing too often (at least from my perspective). Power off 180s were a freaking breeze after that. Not that they're hard but they became that much easier.

Peace

It's not clear how to access that seminar on that Web page.
Sorry about the delayed response on this. Here is a link to the program on “The Possible Turn”. He discusses the factors influencing likely success or failure and how to measure performance for your plane. He also gives some guidelines for deciding on both altitude over the end of the run and altitude to determine if this will be likely possible. (Sort of addresses one of the issues you raised earlier.)

I went out in my Cardinal the other day and I almost never would make the guidelines for a turn back in my 180 hp 1969 model.
