Aircraft Load Ratings
With the publication of TP 312 5th Edition – Aerodrome Standards and Recommended Practices and to align with international practice, the standard method for pavement bearing strength reporting is the ICAO Aircraft Classification Number - Pavement Classification Number (ACN-PCN) method. Aircraft Classification Numbers (ACN's) are available from the aircraft manufacturers.
Airports certified to previous editions of TP 312 are encouraged to use the ACN-PCN methodology specified in TP312 5th Edition. The historical Transport Canada Aircraft Load Rating/Pavement Load Rating (ALR/PLR) system will be phased out by September 2018. Refer to Advisory Circular (AC) 302-011 for a methodology to derived PCN codes from existing PLR data. The table of Aircraft Load Ratings (ALR’s) currently available for downloading will not be updated.
