a
The system is activated when the engine speed exceeds the maximum allowable RPM.
Anytime the engine over-speed system is activated, the warning horn (a) begins to sound
continuously. The system will automatically reduce the engine speed to within the allow-
able limit.
NOTE: Engine speed should never reach the maximum limit to activate the system unless
the propeller is ventilating, an incorrect propeller is being used, or the propeller is faulty.
