1. A method of detecting and predicting hydraulic fluid leakage for an aircraft hydraulic system comprising:

  • sensing at least one parameter associated with said hydraulic system;

    determining, at least in part in response to said sensed parameter, an estimated value indicative of total fluid level or mass;

    combining said estimated value with at least some historical values to provide a prediction for the future value of total quantity indication; and

    displaying an indication at least in part associated with said leakage.
