For what it's worth from someone who went through flying training in the early 90s and then CFS 20 years later.
- some of the instructional techniques I witnessed as a student were appalling and delivered by individuals with a very skewed sense of their own self-importance.
- numerous good people fell by the wayside who should have survived then, and probably would now, because the training system at the time was ill-equipped to deal with anybody having 'issues'. Things have moved on.
- shouting at soldiers works, shouting at aviators does not.
- there is a time and place in the military for aggressive instruction, the cockpit is not one of them.
- anybody who has not instructed (a la CFS) is not informed enough to comment on this matter.
I accept that my last point will be the most controversial but unless you have been fully immersed on both sides of the fence you simply do not have a complete understanding of the issues.
