If the collective is smoothly and gently pulled up to the ceiling, is that detected as a high rate of change ? If not then what happens ? Does the metering valve open no more than max N1/torque allowed for the air density conditions with ensuing RRPM decay or does it try to maintain RRPM at any cost ?
I understand that limits are calculated only but can be overriden and recorded.
Hitting the 30s limit (OEI HI) on the Arriel 2C means engine change.
