Abstract: Towing released length is an important parameter for a certain towing flight, if a failure occurs in measuring procedure, it will cause serious consequences. Aiming at the length counting loss phenomenon, the reasons of counting error are analyzed, from the structure principle, air force and flight process of the length measuring device. The structural improvement method and flight maneuvering route requirements are proposed. The effectiveness of the resolutions is verified by the actual flight.
