Abstract

A procedure and a device for the determination of current airspeeds [] of a rotorcraft [] in a stationary flight regime and/or at low speeds. A calculation system [] incorporates two pairs of polynomial calculation laws [] that are executable successively by pairs. A pair of first polynomial laws [] calculates estimated airspeeds [], consisting respectively of longitudinal and lateral airspeeds, and is constructed through multilinear regression based on parameters relating to simulated flight points [] defined by means of a flight simulator []. A pair of second polynomial laws [] calculates the current airspeeds based on the estimated airspeeds [], and is constructed through multilinear regression based on parameters relating to test-flight points defined by means of test flights [
