| Definition / notes: | To comply with ICAO requirements, Canadian International airports report pavement strengths in a dual format which includes standard international PCN codes. Typical PCN codes are shown on the right hand side of the PLR Chart above. A PCN code has five parts - the first part is the actual PCN number, the second part is the pavement type ("F" for "flexible" or "R" for "Rigid"), and the third part indicates the subgrade strength category ("A" for high and "D" for low strength). The fourth part lists any tire pressure limitation which may apply - a "W" indicates that there is no tire pressure limit. The fifth part indicates the evaluation method used to determine the pavement strength - "T" if derived from an engineering study or "U" if based on satisfactory aircraft usage. The PCN number indicates the suitability of a pavement area for unrestricted operations by any aircraft that has an ACN and tire pressure not exceeding the limits shown on the chart for the stated pavement type and subgrade strength category. |
