Thank you ... I always find it funny when the answer is RTFM, even though it is at my expense this time.

Hello, I've noticed several times that when flying at high altitude (11–12000 ft), the Apache doesn't respond as I expect it to ... Basically, I receive warnings about rotor RPM being low while at 80 / 85 % torque It would seem that the low rpm alert is tied to the amount of collective I pull and not the amount of torque being used. To me, it looks like an error, but since I'm not an expert about helicopter physics, I might be wrong.
