AUTOMATIC FLIGHT CONTROL SYSTEM
PITCH HOLD MODE (PIT)
When the flight director is activated (the FD Key is pressed), Pitch Hold Mode is selected by default. Pitch
Hold Mode is indicated as the active pitch mode by the green annunciation 'PIT'. 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/NOSE DN Keys
• Pressing the CWS Button, hand-flying the aircraft to establish a new pitch reference, then releasing the
CWS Button
