Abstract:
1. A method for determining an air speed of an aircraft comprising an airplane level including at least display, monitoring, alarm, navigation, and flight control systems at a cockpit and an engine level distinct from the airplane level and including the method comprising: measuring, at the engine level, a pod static pressure from ambient air located under the at least one pod of a first engine; determining, at the engine level, an engine total pressure by measuring a plurality of engine parameter values at a selected engine component and then simulating a model of an aerodynamic field and/or a thermodynamic cycle of the selected engine component to deduce the engine total pressure; calculating the air speed of the aircraft using the pod static pressure and the engine total pressure determined at the engine level; transmitting the air speed calculated using the pod static pressure and the engine total pressure to selected systems at the airplane level; and controlling the selected systems at the airplane level using the air speed calculated using the pod static pressure and the engine total pressure.
