Abstract: A device calculates a first air speed representing an estimated air speed during flight using measurements of static pressure and total pressure onboard the aircraft. The device includes a storage device for storing in memory, in case of detection of a ground taxiing of the aircraft, the most recently determined value of static pressure corrected from induced aerodynamic effects. As a result, a second air speed representing the estimated air speed during the ground taxiing may be calculated by implementing a correction and using the most recently determined value of static pressure when the ground taxiing of the aircraft is detected. A method for automatically estimating an air speed of an aircraft is also provided.

Abstract: The device (1) comprises means for registering, in case of detection of a ground taxiing of the aircraft, the last value of static pressure corrected from induced aerodynamic effects.

Abstract: A device for an aircraft moving in an air mass relative to a terrestrial frame of reference. The device can estimate at least one characteristic of a displacement of the air mass relative to the frame of reference. The device receives an element of information about the speed of the aircraft in the frame of reference, receives at least one element of information about the speed of the aircraft in the air, and obtains the characteristic from the speed information elements. The device is capable of receiving an element of information about the angle of attack (?) of the aircraft in the air, and is capable of determining the characteristic on the basis in particular of the angle of attack information element (?).
