aircraft load rating

aircraft load rating (ALR)

Number expressing the relative structural loading effect of an aircraft on a pavement. ALRs are expressed on a scale from 1 (least demanding aircraft) to 12 (most demanding aircraft). ALRs have been assigned to present-day aircraft at their maximum and minimum operating weights and at a specific tire pressure. The ALR should not exceed the pavement load rating (PLR) for unrestricted aircraft operations. The ALR system for ranking aircraft in terms of their pavement-strength requirements is used exclusively in Canada. For the international reporting of aircraft pavement-strength requirements, the ICAO ACN (aircraft classification number) code is used.
