Altitude Hold Mode is automatically armed when the flight director is in either of the following modes:

• Selected Altitude Capture (see Figure 7-7)

• VNV Target Altitude Capture (see Figure 7-17)

The transition to Altitude Hold Mode automatically occurs when the altitude error is less than 50 feet. In

this case, the Selected or VNV Target Altitude becomes the flight director’s altitude reference. The active mode
annunciation ‘ALT’ appears in magenta if the transition was made from VNV Target Altitude Capture Mode.

Turning the ALT SEL Knob while in Altitude Hold Mode changes the Selected Altitude, but not the 

flight director’s altitude reference, and does not cancel the mode.

With the CWS Button pressed, the aircraft can be hand-flown to a new altitude reference. When the CWS 

Button is released at the desired altitude, the new altitude is established as the altitude reference.

Current Speed Control (if available) can be engaged if the autopilot is engaged and Altitude Hold Mode (ALT)

or VNV Target Altitude Capture (ALTV) Mode is active. When the CSC Key is pressed, the Full Authority 
Digital Engine Control (FADEC) varies engine thrust to maintain the desired Airspeed Reference (green Airspeed 
Reference Bug), within a certain control range.

For CSC engagement and disengagement detailed conditions, see the approved Pilot’s Operating 

Handbook (POH).
