Altimeter
A pressure instrument that displays altitude by sensing static air pressure. Pilots set the local altimeter setting (from ATIS, AWOS, ASOS, or ATC) so indicated altitude matches the elevation of the reporting station when on the ground.

- Altimeter and Static System CheckAn inspection and test of the aircraft altimeter and static pressure system required by 14 CFR 91.411 within the preceding 24 calendar months for IFR operations in controlled airspace. It is the second "A" in the AV1ATE inspection mnemonic and is often kept current on training aircraft even for VFR use.
- AME (Aviation Medical Examiner)A physician designated by the FAA to perform medical examinations for pilot certificates. AMEs evaluate vision, hearing, cardiovascular health, and general fitness to determine if applicants meet medical standards.
- AMT (Aviation Maintenance Technician)A certified technician authorized to inspect, repair, and maintain aircraft. AMTs hold Airframe and/or Powerplant (A&P) certificates issued by the FAA after completing approved training and passing written, oral, and practical exams.
- Angle of Attack (AOA)The angle between the chord line of an airfoil (wing) and the relative wind. As angle of attack increases, lift increases up to the critical angle of attack, beyond which the wing stalls regardless of airspeed or attitude.
