A navigation system for an aircraft, including a calculator of an estimated flight path for the aircraft; a device for determining an estimated value of a flight parameter that corresponds to an estimated speed for the extension of at least a portion of the high-lift devices of the aircraft; and a display of an indication for such estimated value. A command process for such a system and an aircraft equipped with such a system are also disclosed.

Navigation system for an aircraft and associated command process

A process wherein an aircraft starts from a cruising position by flying at a cruising speed to reach a position that intercepts the glide slope. The process can include the steps of decelerating from the begin descent speed and the begin descent altitude of the aircraft during a first descent phase with a first flight path angle until reaching a predetermined speed corresponding to an aircraft speed at which the aircraft flaps are extended for transitioning to a first intermediate position; following a second phase of descent at a considerably constant speed with a second flight path angle; and decelerating during a third phase of descent with a third flight path angle to reach the glide slope interception position. The aircraft slats and/or flaps adopt their first intermediate position considerably when transitioning from the second to the third phase of descent.
