Computer-implemented methods for validating a real-time condition of a landing field using aircraft data. One method comprises identifying a plurality of segments of the runway based on a configurable parameter; receiving input data of at least one of a reported runway condition code and a reported braking action of a recently landed aircraft; receiving actual data of an actual runway deceleration profile from the recently landed aircraft for each identified segment of the runway; creating expected data of an expected runway deceleration profile based on the received input data and the received actual data; comparing the received actual data with the created expected data to validate and/or reassess the input data; and transmitting the validated and/or reassessed data to at least one of other approaching aircraft and an airport controller.
