The time is running!
ACN/PCN is replaced by ACR/PCR
Beginning November 28, 2024, the pavement bearing strength of an aircraft operating area must be reported in the AIP based on a PCR value.
The ACN/PCN calculation model is replaced by an ACR-PCR calculation model.
This is based on the respective ICAO and EASA regulations:
- ICAO Aerodrome Design Manual (Doc 9157) ADM Part 3 Pavements – 3. Edition 2022
- EASA Certification Specifications and Guidance Material for Aerodrome Design (CS-ADR-DSN)
