AP DISENGAGEMENT
AUTOPILOT (AP)
AP1 or 2 disengages when:
‐ The flight crew presses the takeover pb on the sidestick
‐ The flight crew presses the corresponding AP pb on the FCU
‐ The flight crew pushes on the sidestick harder than a certain threshold. (Disengagement through
rudder pedals is only active on ground)
‐ The other AP is engaged, except when localizer/glideslope modes are armed or engaged, or
rollout or go-around mode is engaged
‐ The thrust levers are set above the MCT detent and the aircraft is on ground
‐ In a non-precision approach, with FINAL APP mode engaged, the aircraft reaches:
• The MDA/MDH -50 ft (if entered), or 400 ft AGL (if no MDA/MDH is entered), or
• The Missed Approach Point (MAP), depending on which one comes first.
‐ One of the engagement conditions is lost.
Furthermore, in normal law with all protections available, the AP will disconnect if:
‐ High speed protection is active
‐ Angle-of-attack protection is active (α prot +1 ° is reached)
‐ Pitch attitude exceeds 25 ° up, or 13 ° down, or bank angle exceeds 45 °.
The standard way for the flight crew to disengage the AP is to press the takeover pb on the sidestick.
When AP is OFF, the associated FCU pushbutton goes off, and the AP1 (or 2) disappears from the
PFD’s FMA

AP WARNINGS
When the AP is disengaged, the system warns the flight crew:
‐ If the flight crew disengages it with the takeover pb on the sidestick, the warnings are temporary
‐ If the disengagement results either from a failure, from the flight crew pushing the pushbutton on
the FCU, or from a force on the sidestick, the visual and audio warnings are continual.
