Abstract: The invention relates to a flight management assembly (1) comprising two guidance chains (2A, 2B), each one provided with a flight management system (3A, 3B), each of said flight management systems (3A, 3B) carrying out at least one calculation of guidance instructions for the aircraft, the flight management assembly (1) also comprising at least one monitoring unit (4A, 4B) designed to monitor the guidance instructions calculated by the two flight management systems (3A, 3B) in such a way as to be able to detect and identify a defective flight management system, the monitoring unit (4A, 4B) comprising a monitoring device (5) which verifies particularly whether the following three conditions are met: a first derivative of extrapolated cross tracks is positive; a second derivative of extrapolated cross tracks is positive; and extrapolated positions of the aircraft are on the same side of an active segment of the flight plan followed by the aircraft as the current position of the aircraft.

Abstract: A flight management unit includes two guidance subsystems each including a flight management system, each of the flight management systems being configured at least to extract a flight plan from at least one navigation database, to construct a flight trajectory, and to compute guidance commands for the aircraft. The flight management unit also includes at least one monitoring unit configured to compute a guidance command from a validated flight trajectory and a consolidated flight plan and to monitor the guidance command, as well as guidance commands computed by the two flight management systems so as to be able to detect and to identify a defective flight management system.
