Questions Solved Accurately
14 CFR - CORRECT ANSWER✅✅✅See Title 14 of the Code of Federal Regulations
100-hour inspection - CORRECT ANSWER✅✅✅An inspection identical in scope to an
annual inspection. Conducted every 100 hours of flight on aircraft of under 12,500 pounds that
are used to carry passengers for hire.
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.
A.C. - CORRECT ANSWER✅✅✅Alternating current
Acceleration - CORRECT ANSWER✅✅✅Force involved in overcoming inertia, and
which may be defined as a change in velocity per unit of time.
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.
ADC - CORRECT ANSWER✅✅✅See air data computer.
ADF - CORRECT ANSWER✅✅✅See automatic direction finder.
ADI - CORRECT ANSWER✅✅✅See attitude director indicator.
Adiabatic cooling - CORRECT ANSWER✅✅✅A process of cooling the air through
expansion. For example, as air moves up slope it expands with the reduction of atmospheric
pressure and cools as it expands.
Adiabatic heating - CORRECT ANSWER✅✅✅A process of heating dry air through
compression. For example, as air moves down a slope it is compressed, which results in an
increase in temperature.
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.
,ADM - CORRECT ANSWER✅✅✅See aeronautical decision-making.
ADS-B - CORRECT ANSWER✅✅✅See automatic dependent surveillance-broadcast.
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 chart - 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 - CORRECT ANSWER✅✅✅A device that is used, or intended to be used, for
flight.
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, rudder, or even
a trim tab, which provides aerodynamic force when it interacts with a moving stream of air.
Air mass - CORRECT ANSWER✅✅✅An extensive body of air having fairly uniform
properties of temperature and moisture.
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.
Airplane - CORRECT ANSWER✅✅✅An engine-driven, fixed-wing aircraft heavier than
air that is supported in flight by the dynamic reaction of air against its wings.
Airplane Flight Manual (AFM) - CORRECT ANSWER✅✅✅A document developed by the
airplane manufacturer and approved by the Federal Aviation Administration (FAA). It is specific
to a particular make and model airplane by serial number and it contains operating procedures
and limitations.
