Reporting Aerodrome Pavement Strength – ACR/PCR Method

The new ICAO Aircraft Classification Rating – Pavement Classification Rating (ACR-PCR) system comes into force In November 2024, replacing the ACN-PCN calculation method.

Adopting the ACR-PCR system requires a comprehensive understanding of the new system’s requirements for all aerodrome operators as this new method is mandatory for all airports and aerodromes within the scope of EASA and ICAO.

The ACR-PCR method is related to the design of aerodrome pavements. It is based on the relevant ICAO and EASA regulations:

- ICAO Aerodromes, Volume 1 Aerodromes Design and Operations, Annex 14, Ninth Edition, July 2022

- ICAO Aerodrome Design Manual (Doc 9157) ADM Part 3 Pavements, Third Edition 2022.

- EASA Certification Specifications and Guidance Material for Aerodrome Design (CS-ADR-DSN)

This one day course introduces the background, design basics, the calculation method of the ACR and PCR values, and the new regulation. Participants gain a complete understanding with the help of examples and specialities of this new method.
