Pavement classification number

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 apron (or ramp). This helps to ensure that the runways etc. are not subjected to excessive wear and tear, thus prolonging their usable life and promoting safe aircraft operations.
