FAA GROUND SCHOOL TEST
QUESTIONS AND ANSWERS
What causes a turning stall - ANSWER-centrifugal force is added to the weight of the
aircraft, and its not sufficiently counteracted.
FAA The angle of attack at which an airplane wing stalls will. A: Increase if the CG is
moved forward. B: Change with an increase in gross weight. C: remain the same
regardless of gross weight. - ANSWER-C: remain the same
Regarding stability Define Maneuverability - ANSWER-The quality of an aircraft that
permits it to be maneuvered easily and to withstand the stresses that are imposed on it
Regarding stability define controlability - ANSWER-The capability of an aircraft to
respond to the pilots controls especially in regards to flightpath and aircraft attitude.
Explain static stability - ANSWER-The tendency of an aircraft to return to its orientation
after a disturbance
Explain dymanic stability - ANSWER-A tendency of an ocsillating aircraft to return to its
OG position in regards to time.
What is a "Left turning tendency" - ANSWER-A tendency to produce a twisting or
rotating motion around at least one of the three airplanes three axes.
What are the four elements of a left turning tendency - ANSWER-1. Torque reaction
from engine and propeller
2. Corkscrewing effect of the slipstream
3. Asymmetric loading of the propeller (P-factor)
What law of newton comes into play regarding torque reaction. - ANSWER-3rd law. For
every action there is an equal and opposite reaction
How does newtons third law apply to torque reaction in an aircraft - ANSWER-as the
internal parts and propeller are revolving in one direction. an equal force is trying to
rotate the aircraft in the opposite reaction.
During takeoff how does torque reaction affect the aircraft - ANSWER-an additional
turning moment around the vertical axis is induced. More weight is placed on the left
landing gear
What does the pilot do to correct for the torque reaction on takeoff - ANSWER-applies
right rudder or sets a right rudder trim.
What is the corkscrew effect - ANSWER-When wind is blown back by the propeller
spirals around the airplane and strikes the left side of the vertical stabilizer. This causes
the tail to swing right and the nose to yaw left.
, Ture or false: Higher speeds cause the corkscrew effect to be more compressed
causing it to be felt to a greater degree - ANSWER-FALSE
What is another word for the corkscrew effect - ANSWER-The slipstream effect
What is the p factor - ANSWER-Asymmetric thrust from the descending propeller blade
causes a yawing force to the left
FAA What force makes an Airplane turn A: The horizontal component of lift. B: The
vertical component of lift. C: Centrifugal Force - ANSWER-A: The horizontal component
of lift
FAA Which basic flight maneuver increases the load factor on an airplane as compared
to strait and level flight. A: Climbs. B: Turns. C: Stalls - ANSWER-B: Turns
What determines the longitudinal stability of an airplane A: The location of the CG with
respect to the center of lift. B: The effectiveness of the horizontal stabilizer, rudder, and
rudder trim tab. C: The relationship of thrust and lift to weight and drag. - ANSWER-A:
The location of the CG with respect to the center of lift.
Changes in the center of pressure of a wing affect the aircraft's A: Lift/Drag ratio. B:
Lifting capacity. C: Aerodynamic balance and controllability. - ANSWER-C:
Aerodynamic balance and controlablity
What causes an airplane (except a T tail) to pitch nose down when power is reduced
and controls are not adjusted. A: The CG shifts forward when thrust and drag are
reduced. B: The down wash on the elevators from the propeller slipstream is reduced
and elevator effectiveness is reduced. C: When thrust is reduced to less than weight, lift
is also reduced and the wings can no longer support the weight. - ANSWER-B: The
downwash on the elevators from the propeller slipstream is reduced and elevator
effectiveness is reduced.
The amount of excess load that can be imposed on the wing of an airplane depends on
A: The postion of the CG. B: The speed of the airplane. C: Abruptness at which the load
is applied. - ANSWER-B: The speed of the airplane
As speed increases parasitic drag - ANSWER-Increases exponentially
As speed increases Induced drag - ANSWER-increases exponentially
At the bottom of the drag curve this is the area for - ANSWER-Maximum range
What is the maximum range - ANSWER-the speed at which the maximum amount of
speed of distance is obtained per unit of fuel
Relative to the drag curve at what point do you get the maximum distance glide -
ANSWER-The bottom of the drag curve
What causes a wingtip vortex - ANSWER-Leaking of highpressure air from below the
wing to the upper part of the wing that causes a spiral of air. Think tornado
