AIRBORNE DELAY-Amount of delay to be encountered in airborne holding.
AIRCRAFT- Device(s) that are used or intended to be used for flight in the air, and when used in air traffic control terminology, may include the flight crew.
(See ICAO term AIRCRAFT.)
AIRCRAFT [ICAO]- Any machine that can derive support in the atmosphere from the reactions of the air other than the reactions of the air against the earth's surface.
AIRCRAFT APPROACH CATEGORY-A grouping of aircraft based on a speed of 1.3 times the stall speed in the landing configuration at maximum gross landing weight. An aircraft must fit in only one category. If it is necessary to maneuver at speeds in excess of the upper limit of a speed range for a category, the minimums for the category for that speed must be used. For example, an aircraft which falls in Category A, but is circling to land at a speed in excess of 91 knots, must use the approach CategoryB minimums when circling to land. The categories are as follows:
a..Category A- Speed less than 91 knots.
b..
Category B- Speed 91 knots or more but less than 121 knots.
c..
Category C- Speed 121 knots or more but less than 141 knots.
d..
Category D- Speed 141 knots or more but less than 166 knots.
e..Category E- Speed 166 knots or more.
(Refer to 14 CFR Part 97.)
AIRCRAFT CLASSES- For the purposes of Wake Turbulence Separation Minima, ATC classifies aircraft as Heavy, Large, and Small as follows:
a..
Heavy- Aircraft capable of takeoff weights of more than 255,000 pounds whether or not they are operating at this weight during a particular phase of flight.
b..
Large- Aircraft of more than 41,000 pounds, maximum certificated takeoff weight, up to 255,000 pounds.
c.
Small- Aircraft of 41,000 pounds or less maximum certificated takeoff weight.
(Refer to AIM.)
AIRCRAFT CONFLICT- Predicted conflict, within URET, of two aircraft, or between aircraft and airspace. A Red alert is used for conflicts when the predicted minimum separation is 5 nautical miles or less. A Yellow alert is used when the predicted minimum separation is between 5 and approximately 12 nautical miles. A Blue alert is used for conflicts between an aircraft and predefined airspace.
(See USER REQUEST EVALUATION TOOL.)
AIRCRAFT LIST (ACL)- A view available with URET that lists aircraft currently in or predicted to be in a particular sector's airspace. The view contains textual flight data information in line format and may be sorted into various orders based on the specific needs of the sector team.
(See USER REQUEST EVALUATION TOOL.)
AIRCRAFT SURGE LAUNCH AND RECOVERY- Procedures used at USAF bases to provide increased launch and recovery rates in instrument flight rules conditions. ASLAR is based on:
a..
Reduced separation between aircraft which is based on time or distance. Standard arrival separation applies between participants including multiple flights until the DRAG point. The DRAG point is a published location on an ASLAR approach where aircraft landing second in a formation slows to a predetermined airspeed. The DRAG point is the reference point at which MARSA applies as expanding elements effect separation within a flight or between subsequent participating flights.
