Abstract: The guidance system (1) comprises a first means (2) for guiding the aircraft whilst maintaining a spacing with another aircraft, a second means (3) for making the aircraft pass through a particular waypoint at a required passing time, and means (5) for selecting automatically one of said first and second means (2, 3).

Abstract: The device 1 comprises means (3, 4, 5) making it possible to cause the aircraft to pass at least one particular waypoint of the flight trajectory, at an associated target time, and to do so to within an associated temporal tolerance.

Abstract: A method for detecting an error in input of one of the takeoff parameters into a flight management system includes a step of calculating a limit value based on one or more takeoff parameters input into the flight management system. The method further includes a step of comparing the calculated limit value with characteristic takeoff values.

Abstract: System for aiding the piloting of an aircraft during the approach to a runway with a view to a landing. The system (1) comprises information sources (3) able to provide information relating to the aircraft and to its environment, a computation unit (4) which determines, with the aid of information provided by the information sources (3), an energy reference profile which preferably comprises a trajectory reference profile and a speed reference profile and which is intended to allow the aircraft to regain a stabilized approach trajectory, if it follows this reference profile, means of monitoring (7) for verifying that the aircraft is indeed following said reference profile, and means of indication (6) which supply the pilot with piloting indications at least to make it possible to pilot the aircraft in such a way that it always follows said reference profile.
