Question For The Experts - Use Of Flaps.

[SpyderPig]

As Im at work, I cant watch the above vids but I can say that I have been shown the turn back once and it was followed by pretty strict instructions on its use.

In a 152 we set out to perform this maneuver, where just short of 700ft(xwind turn for us) the instructor pulled the power and performed the move. Back on the strip he asked me to perform this as per his prompts, which I did and we landed again safely (quite day at the field).
His instructions were that it was possible, BUT only if you can check these 3 things off can you attempt it.

Good head wind on takeoff, giving a good tailwind to help get back.
Never below 500ft, and even then it shouldnt be below at least 600ft.
No one following you on the runway.

Before anyone says anything, he drove home that landing ahead option 1 and 1a. The only time you should consider this was if in your pre take-off brief you know there is no a safe field off the end of the runway to land in.
Never exceed 30deg AoB.

Ive never attempted it again or been asked to perform it.
Just giving a newbie’s point of view on whats being taught
