ENGINE TACHOMETER SYSTEM - DESCRIPTION AND OPERATION
____________________________________________________
1. General
_______
A. The engine tachometer system measures the speed of the low speed (N1)
rotor and high speed (N2) rotor and provides the speed indication in the
flight compartment. N1 speed is a means of monitoring engine power
output, engine condition, and N1 rotor integrity overspeed. N2 rotor
speed is a means of controlling engine starting and monitoring engine
condition and N2 rotor integrity and overspeed. Power for the system is
28 volts dc from the main power circuit breaker panel P6.
