Abstract
A method for monitoring a shock strut may comprise measuring a first shock strut pressure, measuring an ambient temperature, measuring a shock strut stroke, measuring a second shock strut pressure, and determining a servicing condition of the shock strut based upon the first shock strut pressure, the ambient temperature, the shock strut stroke, and the second shock strut pressure, wherein the servicing condition indicates whether it is desirable for the shock strut to be serviced with at least one of a liquid and a gas. The first shock strut pressure and the shock strut stroke may be measured before the takeoff event with a weight of an aircraft supported by the shock strut.

A method for monitoring a shock strut of an aircraft, comprising:
- measuring a first shock strut pressure;
- measuring an ambient temperature;
- measuring a shock strut stroke;
- measuring a second shock strut pressure;
- determining a servicing condition of the shock strut based upon the first shock strut pressure, the ambient temperature, the shock strut stroke, and the second shock strut pressure;
- and
- servicing the shock strut with at least one of a liquid and a gas based on a determination of a reference curve corresponding to the ambient temperature,
- wherein
- the first shock strut pressure and the shock strut stroke are measured before a takeoff event, and the second shock strut pressure is measured after the takeoff event.
