NASA and MDHC did a quiet rotorcraft test programme in the late 1980's in a 500E. Part of the test programme required that they fly at 75 per cent rotor RPM. To release the aircraft for that test, the test pilot had to do a few autos starting at 75%. Not sure they held the collective for 2 seconds before lowering it! Maybe that was dependent on the entry speed. I hope the test pilot got a bonus payment for that job!
