ASTB E ALL SET QUESTIONS AND ANSWERS SET
A+
✔✔Lateral stability (rolling) - ✔✔an aircraft's initial tendency relative to its longitudinal
axis after being disturbed, its designed quality to return to level flight following a
disturbance such as lift coefficent (a dimensionless quantity that represents the lift
generated by an airfoil of a particular
✔✔lift/drag ratio - ✔✔a number that represents an airfoil's effiency, the ratio of the lift
coefficient to the drag coefficient for a specific angle of attack
✔✔lift-off - ✔✔take off -duh
✔✔load factor - ✔✔the ratio of load supported by an aircraft's lift-generating airfoils to
the aircraft's actual weight, including the mass of its contents. (aka G (gravity) - loading)
✔✔mean camber line - ✔✔an imaginary line between the leading and traiing edges and
halfway between the airfoil's upper (curved) and lower (flat) surface
✔✔minimum drag speed - ✔✔most lift for the least amount of drag
✔✔Nacelle - ✔✔an enclosure made of metal or another durable material that covers an
aircraft engine
✔✔normal category - ✔✔an airplane intended for non-acrobatic operation that seats a
maximum of nine passengers and has a certificated takeoff weight of 12,500lbs or less
✔✔payload - ✔✔the context of aviation, the weight of an aircrafts occupants, cargo, and
baggage
✔✔P-factor - ✔✔precession factor- a propeller driven aircraft's tendency to yaw to the
left when the propeller rotates clockwise
, ✔✔piston engine - ✔✔also known as a reciprocating engine, it is a heat engine that
uses one or more pistons to convert pressure created by expanding, hot gases resulting
from a combusted fuel-air mixture, or a steam pressure, into a rotating motion
✔✔Pitch - ✔✔an airplanes rotation about its lateral axis
✔✔power level - ✔✔the cockpit lever connected to a turbine engine's fuel control unit
(controls fuel input into the engine)
✔✔propeller slipstream - ✔✔air accelerated behind a spinning propeller
✔✔rate of turn - ✔✔in degrees per second
✔✔reciprocating engine - ✔✔converts heat energy created by combustion/ fuel miexed
with air into reciprocating piston movement, which in turn is converted into a rotary
motion via a crankshaft
✔✔reduction gear - ✔✔a gear or set of gears that turns a propeller at a speed slower
than that of the engine
✔✔relative wind - ✔✔the direction of airflow relative to an airfoil, a stream of air parallel
and opposite to an aircraft's flightpath
✔✔ruddervator - ✔✔two control suraces on an aircraft's tail that form a V. when moved
together via a control wheel or joystick in the cockpit, the surfaces act as elevators.
✔✔sideslip - ✔✔a flight maneuver controlled by the pilot that involves the airplanes
longitudinal axis remaining parallel to the original lift componenet causes the plane to
move laterall toward the low wing
✔✔skid - ✔✔a flight condition during a turn where the airplanes tail follows a path
outside the path of the aircraft's nose
✔✔stability - ✔✔an an aircraft's inherent tendency to return to its original flightpath after
a force such as a wind gust disrupts its equilibrium.
✔✔stall - ✔✔a rapid decrease in lift caused by an excessive angle of attack and airflow
separating from an airfoiil's upper surface.
✔✔standard-rate turn - ✔✔a rate of turn of three degrees per second
✔✔subsonic - ✔✔speeds below the speed of sound
