Claim:
1. A method for constructing at least one speed profile (P 1 ) for a descent or an approach of an aircraft looking to land, the speed profile (P 1 ) including a series of constant speed levels (T 1 , T 3 , T 5 ) and deceleration segments (T 2 , T 4 ) along a flight path of the aircraft and being determined for a part of the flight path of the aircraft upstream from a calculation starting point corresponding to the aircraft travelling downstream along the flight path at a downstream speed limit (V 2 ) at a given altitude level (A 2 ) above ground, the method comprising: a) receiving at least one speed constraint (V b) determining at least one portion of the speed profile (P c) maintaining the optimum speed (Vopt) upstream along the aircraft flight path up to a defined second acceleration upstream along the aircraft flight path from the optimum speed (Vopt) directly up to the speed constraint (V whereby the speed profile (P d) transmitting the speed profile (P e) having the user device automatic pilot system guide or help guide the descent or approach of the aircraft using the speed profile (P
