77 - "due to the elevated T/R, the aircraft will snap into a roll;"

Hoss - "So while the the aircraft will quickly be marginally stable and very "loose""

So, agreement? that some level of instability will likely ensue following an unexpected loss of AFCS/SAS. Surely then, response/reaction time becomes the key as to whether the secondary and further effects (e.g. of yaw - induced by sizable aerodynamic anti-torque) have placed the helicopter in a hazardous attitude. The immediacy of any divergence being a factor of airspeed and the amount of divergence, a factor of the time before recovery/intervention.

But this is the bit that surprises me.

Quote 77

"My boss said, that he failed the Heliflight e.g. on a few very seasoned guys and due to the fact that it was never taught in the sim almost all of them did not see the T/R as the cause for the roll and would have rolled it straight into the ground."

Why would this not be taught in the sim?
