A system and method for determining a predicted stopping performance of an aircraft moving on a runway. A predicted stopping force acting on the aircraft to stop the aircraft is determined by a processor unit as the aircraft is moving on the runway. A predicted deceleration of the aircraft moving on the runway is determined by the processor unit using the predicted stopping force acting on the aircraft to stop the aircraft. The predicted stopping performance of the aircraft on the runway is determined by the processor unit using the predicted deceleration of the aircraft.
