ENGINE CONTROL SYSTEM (Cont)
CLIMB THRUST (CLB)
When the thrust lever is placed in the CLB detent, the FADEC electronically programs the engine to accelerate or decelerate
to the climb thrust setting.
The programmed climb thrust value is displayed on the MFD EICAS by the following indications:
- Cyan caret
- Cyan N
1
digital reference
- Cyan CLB thrust mode annunciation
CRUISE RANGE (CRZ)
Cruise power is unlike other thrust settings in that it is not associated with a thrust lever detent.
Cruise power is set by positioning the thrust lever in the quadrant range that exists between the IDLE and CLIMB detents.
In this range, the pilot manually sets the thrust levers to maintain cruise speed or sets thrust for the descent and approach.
In cruise, FADEC does not set the cruise thrust to match the FADEC generated maximum cruise thrust target value. To
distinguish maximum cruise power (CRZ) from other detent-related thrust settings, a cyan N
1
doughnut is used instead of
a caret.
Maximum cruise power (CRZ) is indicated by the following:
- Cyan doughnut
- Cyan N
1
digital reference
- Cyan CRZ thrust mode annunciation
BLEED AIR EXTRACTION
When the thrust levers are in any of the detents and a new bleed air demand is placed on the engines, the N
1
target rpm may
change to compensate for the new bleed-air demands.
