•
A white CSC annunciation in the Engine Indication System
(EIS) display.
To maintain the CSC target speed, the FADEC will modulate engine
thrust in either direction up to 5% N
1
or 5 degrees of equivalent thrust
lever angle change, whichever is more constraining.
CAUTION
Due to CSC's limited control authority, target speed may
not be maintained during all operational scenarios, such
as configuration changes (flaps, speed brake, or landing
gear) or when the flight director is not being followed.
Any of the following methods can be used to disengage the CSC
function:
•
Press the CSC button on the AFCS Mode Control Panel.
•
Move either thrust lever by more than 1 degree.
•
Press the AFCS/Trim Master button on either control yoke.
•
Select a vertical AFCS mode other than Altitude Hold (ALT).
When the CSC function is disengaged, the CSC annunciation on the
FMA flashes amber. All other PFD and EIS CSC indications are
removed upon disengagement. The flashing CSC annunciation is self-
clearing after 5 seconds.
If an attempt to engage CSC is made while the function is not available,
a flashing amber CSC annunciation appears on the FMA. This indication
is also self-clearing after 5 seconds.
If the CSC function detects a failure situation such as invalid sensor data
or FADEC communication, a CRUISE SPD CTRL FAIL advisory
message is displayed.
