Question: Absolute Accuracy
Answer: The ability to determine present position in space independently, and is most often used by pilots.
Question: Absolute Altitude
Answer: The actual distance between an aircraft and the terrain over which it is flying.
Question: Absolute Pressure
Answer: Pressure measured from the reference of zero pressure, or a vacuum.
Question: Acceleration error
Answer: 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.
Question: Accelerate-go distance
Answer: The distance required to accelerate to V1 with all engines at takeoff power, experience an engine
failure at V1, and continue the takeoff on the remaining engine(s). The runway required includes the distance
required to climb to 35 feet by which time V2 speed must be attained.
Question: Accelerate-stop distance
Answer: The 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).
Question: Accelerometer
Answer: A part of an inertial navigation system (INS) that accurately measures the force of acceleration in one
direction.
Question: Adjustable-pitch propeller
Answer: A propeller with blades whose pitch can be adjusted on the ground with the engine not running, but
which cannot be adjusted in flight. Also referred to as a ground adjustable propeller. Sometimes also used to
refer to constant-speed propellers that are adjustable in flight.
Question: Adjustable stabilizer
Answer: A stabilizer that can be adjusted in flight to trim the airplane, thereby allowing the airplane to fly
hands-off at any given airspeed.
Question: Advection fog
Answer: Fog resulting from the movement of warm, humid air over a cold surface.
,Question: Adverse yaw
Answer: A condition of flight in which the nose of an airplane tends to yaw toward the outside of the turn. This
is caused by the higher induced drag on the outside wing, which is also producing more lift. Induced drag is a
by-product of the lift associated with the outside wing.
Question: Aerodynamics
Answer: The science of the action of air on an object, and with the motion of air on other gases. Aerodynamics
deals with the production of lift by the aircraft, the relative wind, and the atmosphere.
Question: Aeronautical chart
Answer: A map used in air navigation containing all or part of the following: topographic features, hazards and
obstructions, navigation aids, navigation routes, designated airspace, and airports.
Question: Aeronautical decision-making (ADM)
Answer: A systematic approach to the mental process used by pilots to consistently determine the best course
of action in response to a given set of circumstances.
Question: Agonic line
Answer: An irregular imaginary line across the surface of the Earth along which the magnetic and geographic
poles are in alignment, and along which there is no magnetic variation.
Question: Ailerons
Answer: Primary flight control surfaces mounted on the trailing edge of an airplane wing, near the tip. Ailerons
control roll about the longitudinal axis.
Question: Aircraft altitude
Answer: The actual height above sea level at which the aircraft is flying.
Question: Aircraft approach category
Answer: A performance grouping of aircraft based on a speed of 1.3 times the stall speed in the landing
configuration at maximum gross landing weight.
,Question: Air Data Computer (ADC)
Answer: An aircraft computer that receives and processes pitot pressure, static pressure, and temperature to
calculate very precise altitude, indicated airspeed, true airspeed, and air temperature.
Question: Airfoil
Answer: Any surface, such as a wing, which provides aerodynamic force when it interacts with a moving stream
of air.
Question: AIRMET
Answer: Inflight weather advisory issued as an amendment to the area forecast, concerning weather
phenomena of operational interest to all aircraft and that is potentially hazardous to aircraft with limited
capability due to lack of equipment, instrumentation, or pilot qualifications.
Question: Airport Diagram
Answer: The section of an instrument approach procedure chart that shows a detailed diagram of the airport.
This diagram includes surface features and airport configuration information.
Question: Airport markings
Answer:
Question: Airport signs
Answer:
Question: Airport Surface Detection Equipment (ASDE)
Answer: Radar equipment specifically designed to detect all principal features and traffic on the surface of an
airport, presenting the entire image on the control tower console; used to augment visual observation by tower
personnel of aircraft and/or vehicular movements on runways and taxiways.
Question: Airport surveillance radar (ASR)
Answer: Approach control radar used to detect and display an aircraft's position in the terminal area.
, Question: Airport surveillance radar approach
Answer: An instrument approach in which ATC issues instructions for pilot compliance based on aircraft
position in relation to the final approach course and the distance from the end of the runway as displayed on
the controller's radar scope.
Question: Air route surveillance radar (ARSR)
Answer: Air route traffic control center (ARTCC) radar used primarily to detect and display an aircraft's position
while en route between terminal areas.
Question: Air Route Traffic Control Center (ARTCC)
Answer: Provides ATC service to aircraft operating on IFR flight plans within controlled airspace and principally
during the en route phase of flight.
Question: Airspeed
Answer: Rate of the aircraft's progress through the air.
Question: Airspeed Indicator
Answer: A differential pressure gauge that measures the dynamic pressure of the air through which the aircraft
is flying. Displays the craft's airspeed, typically in knots, to the pilot.
Question: Air traffic control radar beacon system (ATCRBS)
Answer: Sometimes called secondary surveillance radar (SSR), which utilizes a transponder in the aircraft. The
ground equipment is an interrogating unit, in which the beacon antenna is mounted so it rotates with the
surveillance antenna. The interrogating unit transmits a coded pulse sequence that actuates the aircraft
transponder. The transponder answers the coded sequence by transmitting a preselected coded sequence
back to the ground equipment, providing a strong return signal and positive aircraft identification, as well as
other special data.
Question: Airway
Answer: An airway is based on a centerline that extends from one navigation aid or intersection to another
navigation aid (or through several navigation aids or intersections); used to establish a known route for en
route procedures between terminal areas.
Question: Alert Area
Answer: An area in which there is a high volume of pilot training or an unusual type of aeronautical activity.
Question: Alternate Airport
Answer: An airport designated in an IFR flight plan, providing a suitable destination if a landing at the intended
airport becomes inadvisable.
Question: Alternate static source valve
Answer: A valve in the instrument static air system that supplies reference air pressure to the altimeter,
airspeed indicator, and vertical speed indicator if the normal static pickup should become clogged or iced over.
