This is an interesting thread for three very intriguing reasons:
1) The things we were taught (and that are propagated in the literature) are often simplifications and rules of thumb. They are not strictly correct, but serve as memory aids and physical analogs to help us understand complex situations.
Gyroscopic precession
Centrifugal Force
Ground Cushion
LTE
2) When we try to bend the simplifications to fit other situations, they often break down, and actually hurt our understanding.
3) many Pprune posts are attempts to straighten out theses broken rules of thumb
Thanks Roborider for helping out in this lively debate.
I posted my last wise-guy post to actually try and make someone research the question, and I am very glad it worked!
This thread is an example of how Pprune is great. Thanks, guys.
