A visual approach slope indicator system (VASIS) consisting of only two light units situated on the left side of the runway, one upwind and one downwind. The aircraft is on slope if the upwind unit shows red and the downwind unit shows white, too high if both units show white, and too low if both units show red. The AVASIS is always set to an eye-to-wheel height (EWH) of 10 ft.

Canada: A 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 tyre 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 code is used.
Industry:Aviation
An expression used to prefix an ATC clearance when it is relayed to an aircraft by someone other than the air traffic controller who issued the clearance. The expression is also used in direct controller-pilot communications (DCPC) to differentiate a clearance from an instruction.
Industry:Aviation
An expression used to prefix an ATC request when it is relayed to an aircraft by someone other than the air traffic controller who made the request.

(1) Canada: Short-term meteorological information intended primarily for aircraft in flight, to notify pilots of potentially hazardous weather conditions not described in the current area forecast and not requiring a SIGMET. The criteria for issuing an AIRMET are the unforeseen development, dissipation or non-occurrence of forecast
(a) instrument meteorological conditions (IMC): broken or overcast cloud condition at less than 1000 ft AGL and/or visibility less than 3 SM;
(b) freezing precipitation (not requiring a SIGMET);
(c) moderate icing;
(d) moderate turbulence;
(e) thunderstorms (isolated as opposed to a line);
(f) an increase in the surface mean wind over a large area to 20 kt or more, or an increase in gusts to 30 kt or more, when no winds were originally forecast; or
(g) a difference between the forecast and observed wind direction greater than 60°.
(2) U.S.: In-flight weather advisories issued only to amend the area forecast concerning weather phenomena which are of operational interest to all aircraft and potentially hazardous to aircraft having limited capability because of lack of equipment, instrumentation, or pilot qualifications. AIRMETs concern weather of less severity than that covered by SIGMETs or convective SIGMETs. AIRMETs cover moderate icing, moderate turbulence, sustained winds of 30 kt or more at the surface, widespread areas of ceilings less than 1000 ft and/or visibility less than 3 mi., and extensive mountain obscurement.
