CHANGING THE SELECTED ALTITUDE
NOTE: Holding the CWS Button while in Selected Altitude Capture Mode
does not cancel the mode.
Setting the selected altitude:
1)
From the PFD Page (one display) or PFD (two display), press the ALT/
PTCH Softkey.
2)
Turn the FMS Joystick to set the Selected Altitude in 100-ft increments
Use of the FMS Joystick to change the Selected Altitude while Selected
Altitude Capture Mode is active causes the Integrated Autopilot to revert
to Pitch Hold Mode with Selected Altitude Capture Mode armed for the
new Selected Altitude.
ALTITUDE HOLD MODE (ALT)
Altitude Hold Mode can be activated by pressing the AP ALT Softkey;
the Integrated Autopilot maintains the current aircraft altitude (to the
nearest 10 feet) as the Altitude Reference. The Altitude Reference, shown
in the G300 Autopilot Status Box, is independent of the Selected Altitude,
displayed above the Altimeter. Altitude Hold Mode active is indicated by
a green ‘ALT’ annunciation in the G300 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.
