Pressing the TO/GA Button while the aircraft is airborne activates GA Mode. In GA Mode the flight director commands a pitch-up attitude, allowing the execution of a missed approach or go around. If there is a valid flight plan loaded in the system with GPS lateral guidance, GPS Mode becomes the active lateral mode in preparation for proceeding to the Missed Approach Hold Point. Selecting GA Mode does not disengage the autopilot. If no approach has been loaded, or if there is no FMS lateral guidance, the flight director commands wings level.
