WARNING INDICATIONS
Lower display - Vibration indications.
Vibration tracking is theoretically done in Mils for the LP (N1) rotor and IPS for the HP (N2) rotor.
In order to avoid two different types of unit indication being provided to the crew, the two values are transformed and displayed in cockpit units.
The LP rotor indication is green and pulses above 6 units.
The HP rotor indication is green and pulses above 4.2 units.
If an indication is not available, the corresponding indication is replaced by 2 amber crosses.
