The Aircraft Classification Number (ACN) – Pavement Classification Number (PCN) method is a standardized international airport pavement rating system promulgated by the ICAO in 1981. The method has been the official ICAO pavement rating system for pavements intended for aircraft of apron (ramp) mass greater than 5700 kg from 1981 to 2020. [ 1 ]

Mar 13, 2015 · The ACN-PCN system is structured so a pavement with a particular PCN value can support an aircraft that has an ACN value equal to or less than the pavement's PCN value. This is possible because ACN and PCN values are computed using the same technical basis. Source: Advisory Circular 150-5335-5C, ¶1.2.3

The PCN is the ACN of the most damaging aircraft that can use the pavement on a regular basis (regular being defined by the operator). The PCN values are published in the Aeronautical Information Publications (AIPs), part AD (aerodromes).

Jul 11, 2012 · In the most fundamental terms, the determination of a rating in terms of PCN is a process of deciding on the maximum allowable gross weight of a selected critical airplane for a pavement, and knowing its ACN at that weight, reporting it as PCN.

Jul 22, 2024 · This article delves deep into the transition from the ACN-PCN to the ACR-PCR system for airport pavement strength rating, a new system that optimizes evaluation of pavement strengths. ACN-PCN SYSTEM OVERVIEW: The Precursor to the Latest Reporting System

– The Pavement Classification Number (PCN) –a number expressing the bearing strength of a pavement for unrestricted operations. • If ACN ≤ PCN, the aircraft can operate on the pavement without restriction. • If ACN > PCN, the aircraft cannot operate, or may be allowed to operate subject to weight and/or frequency limitations. 4

Through the Aircraft Classification Number-Pavement Classification Number (ACN-PCN) method, airport managers have a way to determine if their pavements can support aircraft landings at their airport. However, the ACN-PCN method is a new concept to many airport managers.
