A little off topic but I have to share this story... when my company used to fly the Jetstream 31 we would do a Torque/Temp limiter check on the runway before the first flight of the morning. The check involved a fair amount of power being applied with the brakes held and then testing the system which backed down some power automatically which could be heard audibly quite easily by everyone in the airplane. Anyway one of our crews was reported to the FAA as being delinquent because a general aviation Cessna pilot reported that the "Mag Check" was too quick and sounded wrong yet our plane still departed!
LOL!
