ACN-PCN method

In 1981, ICAO proposed to its member states the ACN-PCN method as a standardized system of communication of the information on the strength of airfield pavements.

This method results of a desire to unify the standards for the accommodation of aircraft globally. It resides in a simple comparison between two classification numbers, one assigned to the pavement (PCN – Pavement Classification Number), the other to the aircraft (ACN - Aircraft Classification Number).

This guide aims to describe the method and make accessible the ACN-PCN concept.
