someone I know, cough, happily span down from 11,000 to 2,000 in a very short space of time
I watched someone do the same in a Pa38 - they had not taken into account the lag in the altimeter that builds up over such a fast descent and were a
lot lower than expected when recovery complete!
I find it helpful to remind the beginners that without realising it, they have probably experienced stalls .....after all, a well held off landing is a stall a few inches from the ground!
a commonly held misconception!
