CURRENT SPEED CONTROL (CSC)
Current Speed Control (CSC), if available, can be activated while the autopilot is engaged and Altitude Hold
Mode is active. During CSC, the FADEC varies engine thrust to maintain the desired airspeed (green airspeed
bug), within a certain control range.
When CSC is active, a green arc appears on the N1 gauges, at values corresponding to the current speed
selected (Figure 3-9).
The N1 gauge flashes ‘LIM’ (black text on yellow background) if the CSC maximum authority limit has been
reached for the corresponding engine.

Selecting Current Speed Control (CSC):
1) With the autopilot engaged, select Altitude Hold Mode (see the AFCS Section for details).
2) Press the CSC Key (on the AFCS Control Unit).
