That said, I'm nitpicking the statement rather than the sentiment
Its no problem - on face value I can understand why the statement is not entirely correct. No, you're not going to fall out of the sky with a large AoB, so long as the airspeed is sufficient which prevents a wing stall.
Just lower the nose promptly to maintain safe airspeed and then turn using a decent bank.
Which I believe is what I stated in one of my earlier posts ??
to avoid stalling a wing, you need to put the nose further down to increase your speed, but the problem is that you've run out of airspace cos the engine failed at 500ft ??
If you are an instructor you should get your head around this so that you are able to inform your students.
I have 'got my head' round this thank you very much and well aware of the risk involved in trying to execute a turnback with no engine at low level. Maybe you should read my posts in full and get your head around them
let's take a warrior - Vs (clean) 50 kts, Best climb 79, Best glide 73: 60 degree bank, 2g, Vs goes up by 1.4 multiplier - i.e. 70kts. Uncomfortably close, but not actually above the glide speed.
What you have to understand and perhaps get your head round is simply the fact that a glide speed of 73kts and stall speed of 70kts, an inexperienced, low hours PPL who flies five months of the year will have great difficulty executing a high AoB turn at 400ft above the ground with the engine failed; hence all the flight manuals, POHs and AAIB advice is to land straight ahead; anything else is a death sentence as has unfortunately been so frequently demonstrated;
