PITCH HOLD MODE (PIT)

When the flight director is activated (the FD Key is pressed) or switched (the XFR Key is pressed), Pitch Hold

Mode is selected by default. Pitch Hold Mode is indicated as the active vertical mode by the ‘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. 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

• Pressing the CWS Button, hand-flying the aircraft to establish a new pitch reference, then releasing the

CWS Button
