Abstract
A method for automatically managing a lateral trajectory upon triggering an emergency descent includes determining a value of lateral offset and generating an offset setpoint by using the value of lateral offset. The generating an offset setpoint includes calculating a sum of the value of lateral offset and any initial value of lateral offset defined between a central axis of a protected sector that the aircraft travels along and an initial lateral trajectory. The offset setpoint is selected to be the smaller of the sum or a lateral offset maximum, which maintains the aircraft within the protected sector at all times. The aircraft is then operated to move the aircraft to the offset setpoint during the emergency descent, which helps avoid further air traffic that may be located at different altitude levels within the same protected sector, especially along the central axis.
