AP Button
-- The AP button is used to engage the autopilot and yaw
damper simultaneously. When engaged, the button lights. The
autopilot can be engaged with the aircraft in any reasonable attitude.
With no flight director modes selected, engaging the autopilot rolls
the aircraft to a wings level attitude and holds the existing pitch
attitude. If any flight director modes are selected before the autopilot
is engaged, the autopilot automatically couples to the selected flight
director mode.
