An engine failure alert indication (ENG FAIL) is displayed in amber on the EGT
indicator when the respective engine is operating at a condition below sustainable
idle (50% N2) and the engine start lever is in the IDLE position. The alert remains
until the engine recovers, the engine start lever is moved to CUTOFF, or the
engine fire switch is pulled.
Compact Display
In compact format, the primary and secondary engine indications are combined on
the same display. The N1 and EGT indications are displayed as they are normally.
All other indications change to digital readouts only. N2, oil temperature, and oil
pressure digital readouts turn red or amber if an exceedance occurs. The N2 digital
display is framed with a red box after engine shutdown on the ground if an inflight
exceedance occurred.
Primary and secondary engine indications are displayed in compact format on the
upper DU when the secondary engine indications are selected for display
(manually or automatically) and the lower DU is unavailable. Alternatively, the
compacted indications are displayed on the lower DU if the upper DU is
unavailable.
Selectable Compact Engine Display
The compact engine format may also be selected by pushing the MFD ENG key
on the Engine Display Control panel.
