overpitched
I guess I should have explained myself better.
I work at the main Bell Helicopter Service Center over here, and we get machines from all over that come here for maintenance. Whenever a helicopter first arrives, we fly the aircraft around for a while ourselves to record all parameters, do a power check, check the NR revs in autorotation, and look for anything else unusual. Then before the helicopter leaves we fly it again by ourselves and with the customer to do the same thing.
That is we call a, Maintenace Acceptance Flight.
