Abstract:
1. A method for estimating aircraft airspeed implemented by a processor, comprising the steps of: A/ receiving, by the processor, a value for aircraft aerodynamic speed (Vcaero) based on measured aircraft aerodynamic parameters, which include at least one of mass, load factor, and incidence, with the value for Vcaero being calculated by an aerodynamic speed calculator; B/ receiving, by the processor, a value for current aircraft speed (Vc), the value for Vc being generated by an anemobarometric unit; and C/ determining an estimated airspeed (Vcest) by adding, by an adding unit of the processor, a corrective value, determined by an airspeed integrating unit of the processor, to the value for Vcaero, wherein the corrective value is determined, by the airspeed integrating unit of the processor, according to a comparison, by a comparison unit of the processor, which compares:
