Aircraft type certificate data sheet.
Import manual for the aircraft
The certificate of airworthiness issued by the importing country
(8229)-If a pilot reports that an airplane flies left wing heavy, this condition may be corrected by?
increasing the angle of incidence of the left wing, or decreasing the angle of incidence of the right wing, or both.
increasing the dihedral angle of the left wing, or decreasing the dihedral angle of the right wing, or both .
adjusting the dihedral angle of the left wing so that differential pressure between the upper and lower wing surfaces is increased .
(8230)-If the vertical fin of a single-engine, propeller-driven airplane is rigged properly, it will generally be parallel to?
the longitudinal axis but not the vertical axis.
the vertical axis but not the longitudinal axis .
both the longitudinal and vertical axes .
(8231)-An airplane which has good longitudinal stability should have a minimum tendency to?
roll
Pitch
yaw
(8232)-As the angle of attack of an airfoil increases, the center of pressure will?
move toward the trailing edge .
remain stationary because both lift and drag components increase proportionally to increased angle of attack.
move toward the leading edge.
(8233)-The angle of incidence is that acute angle formed by?
the angular difference between the setting of the main airfoil and the auxiliary airfoil (horizontal stabilizer) in reference to the longitudinal axis of the aircraft.
a line parallel to the wing chord and a line parallel to the longitudinal axis of the aircraft.
a line parallel to the wing from root to tip and a line parallel to the lateral axis of the aircraft.
(8234)-An airplane's center of lift is usually located aft of its center of gravity?
so that the airplane will have a tail-heavy tendency
so that the airplane will have a nose-heavy tendency.
to improve stability about the longitudinal axis.
(8235)-An airplane is controlled directionally about its vertical axis by the?
rudder
elevator(s)
ailerons
(8236)-The elevators of a conventional airplane are used to provide rotation about the?
longitudinal axis
lateral axis
vertical axis
(8237)-Washing-in the left wing of a monoplane, for purposes of rigging corrections after flight test, will have what effect on the lift and drag of that wing?
Both drag and lift will decrease due to decreased angle of attack .
Both drag and lift will increase due to increased angle of attack.
The drag will decrease due to the effect of the lift increase
(8238)-What type of flap system increases the wing area and changes the wing camber?
fowler flaps
slotted flaps
split flaps
(8239)-If the right wing of a monoplane is improperly rigged to a greater angle of incidence than designated in the manufacturer's specifications, it will cause the?
airplane to be off balance both laterally and directionally.
airplane to pitch and roll about the lateral axis.
right wing to have both an increased lift and a decreased drag .
(8240)-The chord of a wing is measured from
wingtip to wingtip.
wing root to the wingtip.
leading edge to trailing edge.
(8241)-When the lift of an airfoil increases, the drag will?
decrease
also increase.
increase while the lift is changing but will return to its original value.
(8242)-What physical factors are involved in the aspect ratio of airplane wings?
Thickness and chord

(8243)-Improper rigging of the elevator trim tab system will affect the balance of the airplane about its?
lateral axis.
Longitudinal axis
Vertical axis
(8244)-An airplane that has a tendency to gradually increase a pitching moment that has been set into motion has?
poor longitudinal stability.
good lateral stability
poor lateral stability
(8245)-The purpose of wing slats is to?
reduce stalling speed.
decrease drag
reduce lift
(8246)-The angle of incidence of an airplane at rest?

does not change when in flight.
(8247)-Buffeting is the intermittent application of forces to a part of an airplane. It is caused by?
incorrect rigging of flaps
an unsteady flow from turbulence.
incorrect rigging of ailerons

around or about the longitudinal axis controlled by the elevator.
around or about the lateral axis controlled by the ailerons.
