Pitch Hold Mode (PIT)
When the flight director is activated (FD Key pressed) or when the autopilot is activated,
Pitch Hold Mode is selected by default. Pitch Hold Mode is indicated as the active vertical mode
by the green 'PIT' annunciation. This mode may be used for climb or descent to the Selected
Altitude (shown above the Altimeter), since Selected Altitude Capture Mode is automatically
armed when Pitch Hold Mode is activated.
In Pitch Hold Mode, the flight director maintains a constant pitch attitude. The pitch
reference is set to the aircraft pitch attitude at the moment of mode selection. If the aircraft
pitch attitude exceeds the flight director pitch command limitations, the flight director
commands a pitch angle equal to the nose-up/down limit.
Changing the pitch reference:
When operating in Pitch Hold Mode, the pitch reference can be adjusted by using
the Nose UP/DN wheel.
Selected Altitude Capture Mode (ALTS)
Selected Altitude Capture Mode is automatically armed with activation of the following
modes:
ƒ Pitch Hold
ƒ Vertical Speed
ƒ Indicated Airspeed
