Damage to gyro instruments
Hello to all,
Section 9 (Towing) of the AMM contains the following:
CAUTION
TO AVOID DAMAGE TO ANY GYRO INSTRUMENTS DO NOT MOVE HELICOPTER ABRUPTLY FOR 10 MINUTES AFTER SWITCHING OFF THE BATTERY OR EXTERNAL POWER SUPPLY.
I know that the OEM is allways right, so follow up on this instruction, but I keep wondering; considering the run down time of a gyroscope, what are the additional stresses to the instruments when you move the machine within, let's say, 5 minutes after power down.
Is anyone aware of some general guideline about this topic?
