Abstract
In various embodiments, a method associating received coefficient of friction data to runway friction estimation map elements. Also, the method may include aggregating the received determined coefficient of friction data into a friction estimation map.
Claims19
A system comprising:
- a tangible, non-transitory memory communicating with a central processor configured to aggregate coefficient of friction data, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the central processor, cause the central processor to perform operations comprising:
- receiving, by the central processor, determined coefficient of friction data for a first series of locations along a runway from a first aircraft of a plurality of aircraft;
- associating, by the central processor, the coefficient of friction data to runway friction estimation map elements;
- receiving, by the central processor, determined coefficient of friction data for a second series of locations along the runway from a second aircraft of the plurality of aircraft;
- and
- aggregating, by the central processor, the received determined coefficient of friction data for the first series of locations along the runway from the first aircraft and the coefficient of friction data for the second series of locations along the runway from the second aircraft into a friction estimation map for the runway;
- and
- performing, by the central processor, temporal calculations to form the friction estimation map, wherein the temporal calculations comprise weighting current data heavier than not current data for overlapping runway friction estimation map elements and updating the not current data with the current data for the overlapping runway friction estimation map elements to reflect a condition change on the runway over time.
