PRACTICE EXAMINATION 2026
QUESTIONS WITH ANSWERS GRADED A+
◍ Aircraft.
Answer: A device that is used or intended to be used for flight in the air.
◍ Four forces of flight.
Answer: lift, weight, thrust, and drag
◍ Three axes of an airplane.
Answer: 1. Lateral - pitch2. Longitudinal - roll3. Vertical - yaw
◍ Lateral axis.
Answer: The horizontal line that passes through the center of gravity of the
aircraft, perpendicular to its flight path. (Controls pitch)
◍ Longitudinal axis.
Answer: Parallel to the fuselage from nose to end of the plane; perpendicular
to the lateral axis. (Controls roll)
◍ Vertical axis.
Answer: A straight line through the center of gravity of the aircraft and at
90° to lateral and longitudinal axis. (controls yaw)
◍ aerospace.
Answer: a combination of aeronautics and space
◍ camber.
Answer: the curved part of an airfoil from its leading to trailing edge
◍ leading edge.
Answer: The front, usually rounded, edge of an airplane wing or airfoil.
,◍ trailing edge.
Answer: The back edge of the wing
◍ relative wind.
Answer: the flow of air which moves opposite the flight path of an airplane
◍ upwash.
Answer: the upward movement of air ahead of the wing in flight
◍ wind.
Answer: the movement of air caused by differences in air pressure
◍ Bernoulli's Principle.
Answer: as the velocity of a fluid increases, the pressure exerted by the fluid
decreases
◍ coanda effect.
Answer: Fluids flowing close to a curved surface follow the shape of the
surface rather than a straight path
◍ angle of attack.
Answer: The acute angle between the direction of the relative wind and the
chord of an airfoil.
◍ altitude.
Answer: the height or distance above a reference plane (usually sea or
ground level)
◍ Convection.
Answer: The transfer of thermal energy by the circulation or movement of a
liquid or gas
◍ density.
Answer: Mass per unit volume
◍ glide ratio.
Answer: a mathematical relationship between the distance an aircraft will
glide forward to the altitude loss
, ◍ lapse rate.
Answer: The rate at which temperature decreases with an increase in
altitude.
◍ soaring.
Answer: the art of staying aloft by exploiting the energy of the atmosphere
◍ stability.
Answer: the atmosphere's resistance to vertical motion
◍ thermal.
Answer: a column of air that moves upwards
◍ combustion chamber.
Answer: An enclosed container in which fuel and air are burned for the
production of energy
◍ tow plane.
Answer: usually a single-engined airplane that will pull a glider from the
ground to an altitude where it can be released
◍ wave.
Answer: A disturbance that transfers energy from place to place
◍ cycle.
Answer: a recurring series of events. The airplane engine has four cycles:
intake, compression, power, and exhaust
◍ fuel.
Answer: a chemical substance which is used as a source of energy; aircraft
fuels include gasoline, kerosene, and propane
◍ lean mixture.
Answer: a mixture of gasoline and air in which there is less fuel and more
air
◍ meter/metering.
Answer: in terms of fuel for an engine, this is the process of allowing a
precise amount of fuel to pass (An example would be a passageway that
