Sandy,
In response....in each situation you mentioned...the pilot has the control....not the aircraft. When the controls quit working...the pilot does not have control.
LTE...the aircraft is fully functional...the controls work...might be the tail rotor does not have the ability to cope with the yawing moment but the controls are working. Judgement is the main issue there....keep your nose into the wind...don't let a yaw rate develop.
407 and its tail rotor....seems like the controls work too good there.
Bell Helicopters and their tail rotors are much akin to the "Jacques Stall" issue. Thus you will not get much argument from me about those issues.
Zero "G"....again the controls got you there....judgement is the issue.
Icing....the controls are working....judgement got you into the ice.
Low, slow, and heavy in a 206.....again...judgement got you there.
Fuel....pilot judgement again.
In the 350....with "Jacques Stall"....too many reports of it happening for it to be a simple judgement thing....gets back to engineering and the controls not working all the time.
