answers
absolute accuracy Correct Answer-The ability to determine present position in
space independently, and is most often used by pilots.
Absolute Altitude Correct Answer-The actual distance between an aircraft and the
terrain over which it is flying.
Absolute Pressure Correct Answer-Pressure measured from the reference of zero
pressure, or a vacuum.
Acceleration Error Correct 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.
Accelerate-go distance Correct 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.
Accelerate-Stop Distance Correct 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).
Accelerometer Correct Answer-A part of an inertial navigation system (INS) that
accurately measures the force of acceleration in one direction.
,Adjustable-pitch propeller Correct 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.
Adjustable stabilizer Correct 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.
Advection fog Correct Answer-Fog resulting from the movement of warm, humid
air over a cold surface.
Adverse Yaw Correct 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.
Aerodynamics Correct 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.
Aeronautical Charts Correct 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.
Aeronautical Decision Making (ADM) Correct 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.
,Agonic Line Correct 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.
Ailerons Correct Answer-Primary flight control surfaces mounted on the trailing
edge of an airplane wing, near the tip. Ailerons control roll about the longitudinal
axis.
Aircraft altitude Correct Answer-The actual height above sea level at which the
aircraft is flying.
Aircraft Approach Category Correct 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.
Air Data Computer (ADC) Correct 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.
Airfoil Correct Answer-Any surface, such as a wing, propeller blade, rudder, or
even a trim tab, which provides aerodynamic force when it interacts with a moving
stream of air.
AIRMET Correct 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.
, Airport diagram Correct 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.
Airport Surface Detection Equipment (ASDE) Correct 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.
Airport Surveillance Radar (ASR) Correct Answer-Approach control radar used to
detect and display an aircraft's position in the terminal area.
Airport surveillance radar approach Correct 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.
Air Route Surveillance Radar (ARSR) Correct Answer-Air route traffic control
center (ARTCC) radar used primarily to detect and display an aircraft's position
while en route between terminal areas.
Air Route Traffic Control Center (ARTCC) Correct Answer-Provides ATC service
to aircraft operating on IFR flight plans within controlled airspace and principally
during the en route phase of flight.
Airspeed Correct Answer-Rate of the aircraft's progress through the air.
