(1) Canada: A restriction to an altitude or altitudes imposed on a flight to ensure that separation criteria are met.
(2) U.S.: An altitude or altitudes, stated in the order flown, which are to be maintained until reaching (sic) a specific point or time. Altitude restrictions may be issued by ATC due to traffic, terrain, or other airspace considerations.
Industry:Aviation
A method of navigation which permits aircraft operation on any desired flight path within the coverage of station-referenced NAVAIDs or within the limits of the capability of self-contained aids, or a combination of these.
Industry:Aviation
The uncontrolled airspace within the boundaries or along the tracks specified on an aeronautical chart, or the controlled airspace within the boundaries or along the tracks specified in the Designated Airspace Handbook (DAH).
Industry:Aviation
ICAO: A number expressing the relative effect of an aircraft on a pavement for a specified standard subgrade category.
Note: ACNs are expressed on a scale from approximately 5 (least demanding aircraft) to 110 (most demanding aircraft). ACNs are applicable only to aircraft having an apron (ramp) mass equal to or greater than 12 600 lb. ACNs have been assigned to present-day aircraft at their maximum and minimum operating masses/weights and at a specific tyre pressure. The ACN should not exceed the pavement classification number (PCN) for unrestricted aircraft operations. The ICAO ACN system is the internationally approved and accepted method for ranking aircraft in terms of their pavement-strength requirements.
Industry:Aviation
The order in which two or more aircraft are cleared to approach to land at an aerodrome.
Industry:Aviation
A term that describes the general position of the aircraft in relation to a fix, point or object when that fix, point or object is approximately 90° to the right or left of the aircraft track.
Industry:Aviation
The provision, throughout the day or a specified portion of the day, of current, routine information to arriving and departing aircraft by means of continuous and repetitive recorded broadcasts.
Industry:Aviation
A beacon used to indicate the location of an aerodrome from the air. Beacons may consist of either a rotating light source or a strobe light.
Industry:Aviation
The provision, by an FSS, of information pertinent to the arrival and departure phases of flight and for transit through a mandatory frequency (MF) area.
Industry:Aviation
(1) A phase that begins when
(a) following the uncertainty phase, the communication search has failed to reveal any news of the aircraft;
(b) an aircraft has been cleared to land and fails to land within 5 min after the estimated time of landing and communication has not been re-established with the aircraft; or
(c) information has been received that indicates that the operating efficiency of the aircraft has been impaired, but not to the extent that a forced landing is likely.
(2) ICAO: A situation wherein apprehension exists as to the safety of an aircraft and its occupants.
