Abstract: A diagnostic method performed onboard an aircraft is provided. The method obtains aircraft state data during landing of the aircraft, via a plurality of avionics and aircraft systems; and determines a landing surface friction condition based on the aircraft state data, using at least one of the plurality of avionics and aircraft systems. A method of evaluating landing surface data onboard an aircraft is also provided. The method receives landing surface friction condition data, prior to landing; computes a required landing distance, based on the received landing surface friction condition data; and when the required landing distance is more than a predetermined threshold, performs a designated task.
