Definitions and Abbreviations Flashcards
Define alternate aerodrome?
Aerodrome to which an aircraft may proceed when it becomes either impossible or inadvisable to proceed to or land at the aerodrome of intended landing.
Define area navigation?
A method of navigation which permits aircraft operation on any desired flight path within the coverage of ground or space-based navigation systems or within the limits of self-contained navigation systems, or a combination of these.
Define augmented crew?
The crew on an aeroplane when it has more than the minimum crew required by the aeroplane certification.
Define the term, barometric vertical navigation?
- A navigation system that presents to the pilot computed vertical guidance referenced to a specified vertical path angle (VPA), nominally 3 degrees.
- The computer-resolved vertical guidance is based on barometric altitude.
- Baro-VNAV approach procedures use a DA/H and not an MDA/H and neither a FAF nor a missed approach point is identified.
- They only use a final approach point only.
Define CAT II precision approach procedure?
A precision instrument approach and landing with a decision height lower than 200 feet, but not lower than 100 feet, and a runway visual range not less than 300 m.
Define CAT IIIA precision approach procedure?
A precision instrument approach and landing that has:
- A decision height lower than 100 feet or no decision height.
- Runway visual range not less than 175m.
Define CAT IIIB precision approach procedure?
A precision instrument approach and landing that has:
- A decision height lower than 50 feet or no decision height.
- A runway visual range less than 175m but not less than 50m.
Define CAT IIIC precision approach procedure?
A precision instrument approach and landing with no decision height an no runway visual range limitations.
Define the term, change over point (CoP)?
The point at which an aircraft navigating on an ATS route defined by reference to very high frequency omnidirectional radio ranges (VOR) is expected to transfer its primary navigational reference from the facility behind the aircraft to the next facility ahead of the aircraft.
Define the term, contaminated runway?
In relation to a runway, more than 25% of the runway surface within the required length and width is covered by surface water, slush or loose snow more than 3 millimetres in depth or ice on any part of the runway surface.
Define decision altitude?
A specified altitude, referenced to mean sea level, in the precision approach at which a missed approach must be initiated if the required visual reference to continue the approach has not been established.
Define decision height?
A specified height, referenced to the runway threshold, in the precision approach at which a missed approach must be initiated if the required visual reference to continue the approach has not been established.
Define the term, escorted passenger?
Any passenger requiring the personal attendance of an appointed escort, during an air transport operation.
Define flight level?
Altitude expressed in terms of hundreds of feet that is related to a specific datum of 1013.2 hPa and is separated by specific pressure intervals.
Define IFR flight?
Flight conducted in accordance with the instrument flight rules.
Define Instrument Approach Procedure?
A series of predetermined manoeuvres by reference to flight instruments with specified protection from obstacles from the beginning of a defined arrival route, to a point from which a landing can be completed and if a landing is not completed, to a position at which holding, or en-route obstacle clearance criteria apply.
