Department of the Government of Canada responsible for developing regulations, policies and services of transportation in Canada. It is part of the Transportation, Infrastructure and Communities (TIC) portfolio. Transport Canada is based in Ottawa, Ontario
(1) An indicator that is in the form of a truncated cone made of fabric and that is not less than 12 ft long and, at the larger end, not less than 3 ft in diameter, so constructed as to give a clear indication of the direction of surface wind and a general indication of wind speed.
(2) An actuated device for indicating visually to aircraft the direction of surface wind.
Industry:Aviation
An approach slope indicator system consisting of four light units situated on the left side of the runway in the form of two wing bars referred to as the upwind and downwind wing bars. The aircraft is on slope if the upwind bar shows red and the downwind bar shows white, too high if both bars show white, and too low if both bars show red. Some aerodromes serving large aircraft have three-bar VASIS, which provide two visual glide paths (GP) to the same runway. The VASIS can be situated so as to provide three types of eye-to-wheel height (EWH): V1 (10 ft), V2 (25 ft) and V3 (25 ft and 45 ft).
Industry:Aviation
Aerodrome facilities, including mechanical and electro-optical devices, providing vertical visual approach slope guidance to aircraft during the approach to landing. Lighting facilities provide this guidance by radiating a directional pattern of high-intensity red and white focused light beams that indicate to the pilot that he or she is "on slope," "above slope" or "below slope," depending on the combinations of lights that are showing. These lights are visible from at least 4 NM away (2.5 NM away for abbreviated installations). Visual approach slope indicator systems provide safe wheel clearance over the runway threshold and are related to the eye-to-wheel height (EWH) of the aircraft that the aerodrome is intended to serve.
Industry:Aviation
The agency, organisation or military command responsible for the activity for which Class F airspace has been provided. The user agency shall be identified for Class F restricted areas, military operations areas, and danger areas and, where possible, should be identified for Class F advisory areas.

(1) Canada: Phase that begins when:
(a) with the exception of an arrival report, no communication has been received from an aircraft within 30 min after the time a communication should have been received, or from the time an unsuccessful attempt to establish communication with such aircraft was first made, whichever is the earlier;
(b) a flight plan (FP) has been filed and no arrival report has been received by the area control centre (ACC)
(i) within 1 hr after the estimated time of arrival (ETA) last notified to or estimated by the ACC, whichever is later; or
(ii) at the search and rescue (SAR) time requested by the originator, whichever is earlier;
(c) a flight itinerary (FI) has been filed and no arrival report has been received by the ACC
(i) within 24 hrs after the latest ETA; or
(ii) at the SAR time requested by the originator, whichever is earlier;
(d) an FP or FI has been filed and it is determined that no arrival report can be expected either because there is no communication system serving the point of arrival or the system serving the airport is inoperative.
(2) ICAO: A situation wherein uncertainty exists as to the safety of an aircraft and its occupants.
Industry:Aviation
A specified geographical location, defined by longitude and latitude, that is used in the definition of routes and terminal segments and for progress-reporting purposes.
Industry:Aviation
The rules that govern the procedures for conducting flight under visual conditions.
Note: The abbreviation "VFR" is used by pilots and controllers to indicate a type of flight plan (FP) or weather conditions.
Industry:Aviation
The provision, by FSSs, of commands and instructions to control the movements of ground traffic on manoeuvring areas at designated uncontrolled aerodromes.
Industry:Aviation
An expression indicating that the pilot is using a hood to restrict visibility outside the cockpit while simulating instrument flight. An instrument-rated pilot is required in the other control seat while this operation is being conducted.

U.S. and Canada: The augmentation to global positioning system (GPS) to meet en route and terminal navigation, non-precision approach and precision approach CAT I accuracy, integrity, continuity and availability requirements. The ground system comprises a sparse network of ground reference stations and a master station linked by terrestrial communications. In the space system, an uplink from the master station provides information to geostationary satellites that transmit an integrity message, corrections and a GPS ranging signal to user avionics.
