I don't know the numbers, 50-60 maybe, but not one, having done the "under the hood" stuff as required by the syllabus, and standards, (all PPL) not one lasted more than 70sec., mostly around 30-35 sec., in the real world. As a matter of interest, not mentioned in previous post, whether I flew the aircraft into the Cu, and said "handing over", or the candidate flew into the cloud, the time to loss of control was not materially different.
Aircraft involved, mostly PA-28 or C-150/152/172/182.
Huh? I find that VERY hard to believe!
I knew I was good but I didn't realise what an incredibly talented PPL I was!
