Abstract
A method for determining the flight velocity of an aircraft comprising a flow body is provided. The method comprises acquiring a change in length of a structural component connected to the flow body; determining at least one aerodynamic force acting on the flow body based on the acquired change in length of the structural component connected to the flow body; determining a flow coefficient of the flow body; and calculating the incident flow velocity on the flow body, taking into account the determined flow coefficient and the determined aerodynamic force. With this method reliable determination of the flight velocity can take place without measuring the dynamic pressure.
