N2 (HP Compressor)
The N2 signals are used by the EEC for engine control functions and are used by the Engine Vibration Monitor Unit (EVMU).
N2 is measured by four speed probes per engine, mounted in the accessory gearbox.
Three speed probes are used by the EEC for the following:
.
Variable stator vane control
.
Bleed valve control
.
Start/relight
.
Redline limiting
.
Idle control
.
Surge protection/recovery
.
Overspeed protection
