Exam Questions and CORRECT 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 to rotate
to the 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 inertial navigation system (INS) that
accurately measures the force of acceleration in one direction.
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
,Automatic Direction Finder (ADF) - CORRECT ANSWER - Electronic Navigation
equipment that operates in the low and medium-frequency bands. Used in conjunction with the
ground-based nondirectional beacon (NDB), the instrument displays the number of degrees
clockwise from the nose of the aircraft to the station being received
Attitude Direction Indicator (ADI) - CORRECT ANSWER - An aircraft attitude indicator
that incorporates flight command bars to provide pitch and roll commands
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
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
Automatic Dependent Surveillance-Broadcast (ADS-B) - CORRECT ANSWER -A
function on an aircraft or vehicle that periodically broadcasts its state vector (i.e., horizontal and
vertical position, horizontal and vertical velocity) and other information
Advection Fog - CORRECT ANSWER - For 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 Chart - CORRECT ANSWER - A map used in air navigation containing all
or part of the following: Topographical Features, Hazards and Obstructions, Navigation aids,
Navigation Routes, Designated Airspace, and Airports
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.
Airfoil - CORRECT ANSWER - Any surface, such as a wing, propeller, 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 of 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
Airspeed Indicator - CORRECT 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.
Air Traffic Control Radar Beacon System (ATCRBS) - CORRECT ANSWER - Sometimes
called the 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
