I suspect Mr Alan Cassidy would have something to say about this.
"Right, so stall is down to angle of attack?"
"Yes."
"Where's the angle of attack indicator in the kind of aircraft you'll fly?"
"Ummmm..."
"OK, so take a PA-28... you can paint a line on the column.
Keep pulling, you see the line, that where's where it stalls."
Simple really, when a very experienced pilot explains it.
So, err, no - I concur with a few other people here - can't see how it helps vs. 'normal' flying.
