Changing the Selected Altitude while Selected Altitude Capture Mode is active
causes the autopilot to revert to Pitch Hold Mode with Selected Altitude Capture Mode
armed for the new Selected Altitude.
3.1.13.3 ALTITUDE HOLD MODE (ALT)
Altitude Hold Mode can be activated by pressing the
ALT
Key; the AFCS maintains
the current aircraft altitude (to the nearest 10 feet) as the Altitude Reference. Altitude
Hold Mode active is indicated by a green ‘ALT’ annunciation in the G5 Autopilot Status
Box.
Altitude Hold Mode is automatically armed when in Selected Altitude Capture Mode.
Selected Altitude Capture Mode automatically transitions to Altitude Hold Mode when
within 50 feet of the Selected Altitude. In this case, the Selected Altitude becomes the
Altitude Reference.

When operating in Altitude Hold Mode, the Altitude Reference can be adjusted in
the following ways:
•
The Altitude Reference can be adjusted up or down in 10-foot increments
by rolling the
NOSE UP/DN
Wheel. Using this method, up to 200 feet of
altitude change can be commanded. To change the Altitude Reference by
more the 200 feet, use the CWS button (if equipped) as described below, or
climb/descend using another vertical mode (PIT, VS) to capture the desired
Selected Altitude.
•
If the aircraft is equipped with a CWS Button, pressing the CWS Button allows
the aircraft to 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.
