Glossary
Abeam Fix – A fix, NAVAID, point, or object positioned approximately 90 degrees to the right or left of
the aircraft track along a route of flight. Abeam indicates a general position rather than a precise point.
Accelerate-Stop Distance Available (ASDA) – The
runway plus stopway length declared available and
suitable for the acceleration and deceleration of an airplane aborting a takeoff.
Aircraft Approach Category – A grouping of aircraft
based on reference landing speed (VREF), if specified,
or if VREF is not specified, 1.3 VSO (the stalling speed
or minimum steady flight speed in the landing configuration) at the maximum certificated landing weight.
Airport Diagram – A full-page depiction of the airport
that includes the same features of the airport sketch
plus additional details such as taxiway identifiers, airport latitude and longitude, and building identification.
Airport diagrams are located in the U.S. Terminal
Procedures booklet following the instrument approach
charts for a particular airport.
Airport/Facility Directory (A/FD) – Regional booklets published by the National Aeronautical Charting
Office (NACO) that provide textual information about
all airports, both VFR and IFR. The A/FD includes runway length and width, runway surface, load bearing
capacity, runway slope, airport services, and hazards
such as birds and reduced visibility.
Airport Sketch – Depicts the runways and their length,
width, and slope, the touchdown zone elevation, the
lighting system installed on the end of the runway, and
taxiways. Airport sketches are located on the lower left
or right portion of the instrument approach chart.
Air Route Traffic Control Center (ARTCC) – A
facility established to provide air traffic control service
to aircraft operating on IFR flight plans within controlled airspace and principally during the en route
phase of flight
Air Traffic Service (ATS) – Air traffic service is an
ICAO generic term meaning variously, flight information service, alerting service, air traffic advisory service, air traffic control service (area control service,
approach control service, or aerodrome control service).
Approach End of Runway (AER) – The first portion
of the runway available for landing. If the runway
threshold is displaced, use the displaced threshold latitude/longitude as the AER.
Approach Fix – From a database coding standpoint, an
approach fix is considered to be an identifiable point in
space from the intermediate fix (IF) inbound. A fix
located between the initial approach fix (IAF) and the
