Abstract:
1. A method of monitoring internal fluid levels in a landing gear on an aircraft, the landing gear comprising a telescopic strut, the internal fluids comprising a compressible fluid and an non-compressible fluid, which telescopic strut is capable of extension, comprising the steps of: a) exercising the strut while the aircraft is transporting passengers or cargo; b) while the strut is exercised, allowing the strut to extend fully; c) while the strut is exercised and fully extended, determining a measured pressure of the fluids in the strut over elapsed time; d) determining if the measured pressure is higher than a predetermined pressure of a fully extended strut containing proper volumes of the compressed fluid and the non-compressed fluid; and e) determining from the measured pressure the respective amounts of compressible and non-compressible fluid in the strut.
