Method and device for automatically estimating an air speed of an aircraft

A process for automatically estimating an estimated air speed of an airplane, the process wherein, automatically and repeatedly, the following operations are performed:

• measuring a plurality of ambient pressure measurements using a set of pressure probes on board the airplane;
• determining the static pressure and the total pressure using the pressure measurements performed by the set of pressure probes;
• calculating a first air speed with a calculation device using the static pressure and the total pressure, the first air speed, representing the estimated air speed during flight,
• monitoring parameters of the airplane with a monitoring device to thereby detect a ground taxiing of the airplane;
• and
• should a ground taxiing of the airplane be detected, storing a most recently determined value of static pressure in a memory with a storage device, and implementing a correction to the estimated air speed with a correction device integrated into the calculation device, by repeatedly performing the following operations:
• determining the total pressure using the pressure measurements performed by the set of pressure probes during the ground taxiing;
• and
• calculating a second air speed with the correction device based on the determined total pressure during the ground taxiing and the stored static pressure from the memory and without using a static pressure determined during the ground taxiing, the second air speed representing the estimated air speed during the ground taxiing.
