The pavement classification number (PCN) is an International Civil Aviation Organization standard used in combination with the aircraft classification number (ACN) to indicate the strength of a runway, taxiway or airport ramp (or apron). This helps to ensure that the airport ramp is not subjected to excessive wear and tear, thus prolonging its life.
