  • Aircraft prognostic systems and methods for determining adaptive time between overhaul for line replaceable units
    Patent number: 9568912
    Abstract: Prognostic systems and methods for providing adaptive Time Between Overhaul (TBO) value for one or more Line Replaceable Units (LRUs) are provided. In one embodiment, the LRU prognostic system includes a first LRU, an aircraft position data source configured to monitor the position of an aircraft carrying the LRU prognostic system, and a controller coupled to the first LRU and to the aircraft position data source. The controller is configured to: (i) estimate the degradation of the first LRU based at least in part on the duration of time the aircraft position resides in any one of a plurality of different environmental zones while the aircraft is operational, and (ii) calculate an adaptive TBO value for the first LRU utilizing the estimated LRU degradation.
