Abstract:
1. A flight management computer carried onboard an aircraft, the computer comprising: an input unit for inputting and parameterizing geographical elements and flight constraints associated with the geographical elements for defining, in a flight plan, a skeleton of a route to be followed leading to a landing runway; a formulating unit for formulating a three-dimensional continuous trajectory taking the route to be followed while complying with performance of the aircraft and the flight constraints; a guidance unit for ensuring formulation of piloting instructions and/or orders relating to management of thrust of engines and of an aerodynamic configuration of the aircraft that includes lift-enhancing devices at intermediate deployment positions for following the three-dimensional continuous trajectory formulated and for complying with the associated flight constraints; an input and parameterize unit for inputting and parameterizing a speed constraint that is applicable in a landing runway approach phase, until the aircraft crosses a point at which the speed constraint ends, the point being labelled on the three-dimensional continuous trajectory with respect to a radio beacon, wherein in an operating mode of controlling and holding an approach speed, the guidance unit is configured for choosing the maximum speed value between the speed constraint and an instruction speed as a target speed in each of the intermediate deployment positions of the lift-enhancing devices, the instruction speed being appropriate to a configuration of deployment of lift-enhancing devices.
