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.
