Pavement Classification Number (PCN) 1
Pavement Classification Number (PCN) 1 : (ICAO) A number expressing the bearing strength of a pavement for unrestricted aircraft operations.. Note: PCNs are expressed on a scale from approximately 5 (weakest pavements) to 110 (strongest pavements) and are linked to the pavement type and a standard subgrade category. Aircraft tire pressure restrictions, where applicable, are contained within the PCN reporting code. The ICAO PCN system is the internationally approved and accepted method for the reporting of airport pavement bearing strengths. In Canada, the pavement load rating (PLR) chart for each airport reports bearing strength using both the ICAO PCN and the Canadian PLR code. See also: Pavement Load Rating (PLR)
