8/15/19 1/30/20  Pilot/Controller Glossary Pilot/Controller Glossary  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  Category B minimums when circling to land. The  categories are as follows:  b.  Category B- Speed 91 knots or more but less  than 121 knots.  a.  Category A- Speed less than 91 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 Super, Heavy, Large, and Small as follows:  a.  Super. The Airbus A-380-800 (A388) and the  Antonov An-225 (A225) are classified as super.  b.  Heavy- Aircraft capable of takeoff weights of  300,000 pounds or more whether or not they are  operating at this weight during a particular phase of  flight.  c.  Large- Aircraft of more than 41,000 pounds,  maximum certificated takeoff weight, up to but not  including 300,000 pounds.  d.  Small- Aircraft of 41,000 pounds or less  maximum certificated takeoff weight.  (Refer to AIM.)  AIRCRAFT CONFLICT- Predicted conflict, within  EDST 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  EN ROUTE DECISION SUPPORT  TOOL .)  AIRCRAFT LIST (ACL)- A view available with  EDST 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  EN ROUTE DECISION SUPPORT  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.  b.  ASLAR procedures shall be covered in a Letter  of Agreement between the responsible USAF  military ATC facility and the concerned Federal  Aviation Administration facility. Initial Approach  Fix spacing requirements are normally addressed as  a minimum.  AIRCRAFT HAZARD AREA (AHA)- Used by  ATC to segregate air traffic from a launch vehicle,  reentry vehicle, amateur rocket, jettisoned stages,  hardware, or falling debris generated by failures  associated with any of these activities. An AHA is  PCG A-6
