ALTITUDE HOLD MODE (ALT)
Altitude Hold Mode can be activated by pressing the ALT Key; the flight director maintains the current
aircraft altitude (to the nearest 10 feet) as the Altitude Reference. The flight director’s Altitude Reference,
shown in the AFCS Status Box, is independent of the Selected Altitude, displayed above the Altimeter.
Altitude Hold Mode is indicated by a green ‘ALT’ annunciation in the AFCS Status Box.
Altitude Hold Mode is automatically armed when the flight director is in Selected Altitude Capture Mode
(see Figure 7-6). Selected Altitude Capture Mode automatically transitions to Altitude Hold Mode when the
altitude error is less than 50 feet. In this case, the Selected Altitude becomes the flight director’s Altitude
Reference.
When operating in Altitude Hold Mode, the reference altitude can be adjusted by using the NOSE UP/DN
Wheel. The reference altitude can only be moved a maximum of 150 ft from the current aircraft altitude; each
click changes the reference altitude by 10 ft.
NOTE: 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.
