A

AAM (air-to-air missile). A missile carried on an aircraft for use against other aircraft. The missile is guided to its target by radar or infrared sensors.
AAR (airport acceptance rate) (air traffic control). A dynamic input parameter specifying the number of arriving aircraft which an airport or airspace can accept from the ARTCC per hour.
The AAR is used to calculate the desired interval between successive arrival aircraft.
A & B hydraulic brake system. A form of backup brake system used in some large aircraft multiple-disk power brake installations.
Wheels using the A & B system have several small actuating cylinders built into the brake housing. Half of the cylinders are actuated by fluid from the A-hydraulic system and the others by fluid from the B-system.
The brakes operate normally with either system.
A & P mechanic. A person who holds an aircraft mechanic certificate with both the airframe and powerplant ratings. This certification is issued by the Federal Aviation Administration under the provisions of Federal Aviation Regulations Part 65.
Mechanic certification with an A&amp rating is scheduled to be replaced by AMT (aviation maintenance technician) certification with an aircraft rating under the proposed 14 CFR Part 66.
AAS (airport advisory service). A service provided by FAA Flight Service Stations located at airports not served by a control tower.
AAS provides information to arriving and departing aircraft concerning wind direction and speed, favored runway, altimeter setting, pertinent known traffic, pertinent known field conditions, airport taxi routes, traffic patterns, and authorized instrument approach procedures. AAS information is advisory in nature and does not constitute an ATC clearance.
abampere. A basic unit of electrical current in the electromagnetic-centimeter-gram-second system. One abampere is equal to 10 amperes in the absolute meter-kilogram-second-ampere system. The abbreviation for abampere is aA.
A-battery. A dry-cell battery used in vacuum tube radios to supply power to the heaters, or filaments, of the tubes.
A-batteries usually have a voltage ranging between 1.5 to 6.0 volts and are capable of supplying a reasonable amount of current.
abbreviated IFR flight plan (air traffic control). An authorization by ATC requiring pilots to submit
only that information needed for the purpose of separation and control. An abbreviated flight plan includes only a small portion of the usual IFR flight plan information which may be only aircraft identification, location, and pilot request.
Abbreviated flight plans are frequently used by aircraft which are airborne and desire an instrument approach, or by aircraft which are on the ground and desire a climb to VFR-On-Top.
abcoulomb. A basic unit of electrical charge in the electromagnetic-centimeter-gram-second system. One abcoulomb is equal to 10 coulombs in the absolute meter-kilogram-second-ampere system. The abbreviation for abcoulomb is aC.
abeam. A relative location approximately at right angles to the longitudinal axis of an aircraft. When an
