CAP GEN Long Description of Aviation Terms Flashcards
Pages 9-14 of the CAP GEN Oct 2023 long descriptions of aviation terms
ACCELERATE STOP DISTANCE AVAILABLE (ASDA):
The length of the take-off run available plus the length of the stopway, if provided.
AERODROME:
Any area of land, water (including the frozen surface thereof) or other supporting surface used,designed, prepared, equipped or set apart for use, either in whole or in part, for the arrival, departure,movement or servicing of aircraft: This includes any buildings, installations and equipment situated thereon or associated therewith.
AERODROME ELEVATION:
The elevation of the highest point of the landing area.
AERODROME TRAFFIC FREQUENCY AREA (ATF):
An area within which a VHF frequency is designated to ensure that all radio equipped aircraft operating on the ground or within the specified area are listening on a common frequency and following a common reporting procedure.
APRON:
That part of an aerodrome, other than the manoeuvring area, intended to accommodate the loading and unloading of passengers and cargo; the refuelling, servicing, maintenance and parking of aircraft; and any movement of aircraft, vehicles and pedestrians engaged in services for such purposes.
BEFORE PROCEEDING ON COURSE (BPOC):
A term used to indicate that a specified procedure must be completed prior to taking action to intercept the desired course.
CLEARWAY:
A defined rectangular area on the ground or water under the control of the appropriate authority selected or prepared as a suitable area over which an aeroplane may make a portion of its initial climb to a specified height (TODA-TORA).
CONTOUR RELIEF:
Smoothed contour lines are depicted on Instrument Approach Procedures, SID and STAR when terrain exceeds 4000 feet above the airport elevation, or when terrain within 6 NM of the Aerodrome Reference Point (ARP) rises to exceed 2000 feet above the aerodrome elevation.
Contour lines, values and tints are printed in brown and will begin at 500 feet above the aerodrome elevation and shall be depicted by smoothed contours in intervals of 1000 feet.
Contour lines and values will not be depicted on SID and STAR charts represented at a scale of 1:1,000,000 or greater, but gradient tints shall be shown. Gradient tints indicate the elevation change between contour intervals. The absence of terrain contour information does not ensure the absence of terrain or structures.
DEAD RECKONING:
The estimating or determining of current position by advancing an earlier known position by the application of direction, time and speed data. Heading information depicted on a dead reckoning segment intercepts the inbound track prior to the IF. The distance shown is the total track distance to the IF. (i.e. “2900 Hdg 238º 10 NM to IF”)
DECISION ALTITUDE (DA):
An altitude specified on a precision approach procedure or an approach procedure with vertical guidance at which the missed approach procedure shall be initiated if the required visual reference necessary to continue the approach to land has not been established.
DECISION HEIGHT (DH):
The height of the DA above the touchdown zone elevation or runway threshold.
DUPLICATE PROCEDURES:
Two or more approach procedures to the same runway that cannot be uniquely distinguished by the navigation type indicator only.
FINAL APPROACH AND TAKE-OFF AREA (FATO):
A defined area over which the final phase of the approach manoeuvre to hover or landing is completed and from which the take-off manoeuvre is commenced.
GROUND ADVISORY SERVICE (GND ADV):
At select ATS sites where an MF is in effect and the volume of traffic is such that a second frequency is needed to alleviate congestion on the radio, traffic information services, pre-taxi clearances and other advisory services are provided on a ground advisory (GND ADV) frequency. Following an order from the Minister, the requirements for CAR 602.97(2), 602.98(1) and 602.99 can be waived providing pilots remain on the appropriate frequency while in the MF area. Pilots must still adhere to CAR 602.100 to 602.103 inclusive.
HAZARD BEACON:
An aeronautical beacon used to designate a danger to air navigation.
HEIGHT ABOVE AERODROME (HAA):
The height in feet of the MDA above the aerodrome elevation. HAA is charted for all circling minima.
HEIGHT ABOVE THE SURFACE (HAS):
The height in feet of the MDA above the highest terrain/surface within a 5200 foot radius of the MAP in Point-in-Space helicopter procedures.
HEIGHT ABOVE THRESHOLD (HATh):
The height in feet of the DA or MDA above the runway threshold elevation. HATh is charted for some straight-in minima.
HEIGHT ABOVE TOUCHDOWN ZONE ELEVATION (HAT):
The height in feet of the DA or MDA above the Touchdown Zone Elevation. HAT is charted for some straight-in minima.
HELIPORT:
An aerodrome or a defined area on a structure intended to be used wholly or in part for the arrival, departure and surface movement of helicopters.
HOLDING BAY:
A defined area where aircraft can be held, or bypassed, to facilitate efficient surface movement of aircraft.
HOLDING/SHUTTLE PATTERN:
A predetermined manoeuvre which keeps an aircraft within a specified airspace while awaiting further clearance or while climbing/descending to a predetermined altitude. Hold and shuttle patterns depicted with a left hand turn are considered non-standard. When charted, the airspeed shown inside the hold or shuttle pattern indicates the maximum assessed indicated speed.
HOT SPOT:
A location on an aerodrome movement area with a history of or a potential risk for collisions or runway incursions and where heightened attention by pilots is necessary.
