Visual illusion
Dear readers / collegues,
First of all I would like to apologize for not reading every posting here. I did read about 50% though.
I have 16 years of 737 experience, of which most as test-pilot and instructor.
I 've seen no reactions so far regarding possible visual illusion during cloud break. Low cloudbase at 700' and visibility of 4000m tempo 2500m can give a momentary impression of extreme low pitch. This is a scary sensation when you are at low altitude. An agressive reaction to this sensation could have been an agressive pitch-up, resulting in an accellerated stall. A pitch down movement would be normal after such a stall, this is per aeodynamic 'stable' design. As an instructor, you would have no options left to counteract such an act of your student....
