A.C. Alternating current. | |
Absolute accuracy The ability to determine present position in space independently, and is most often used by pilots. | |
Absolute altitude The actual distance between an aircraft and the terrain over which it is flying. | |
Absolute pressure Pressure measured from the reference of zero pressure, or a vacuum. | |
Accelerate-stop distanceThe distance required to accelerate to V1 with all engines at takeoff power, experience an engine failure at V1, and abort the takeoff and bring the airplane to a stop using braking action only (use of thrust reversing is not considered). | |
Acceleration Force involved in overcoming inertia, and which may be defined as a change in velocity per unit of time. | |
Acceleration error A magnetic compass error apparent when the aircraft accelerates while flying on an easterly or westerly heading, causing the compass card to rotate toward North. | |
Accelerometer A part of an inertial navigation system (INS) that accurately measures the force of acceleration in one direction. | |
ADC See air data computer. | |
