ASSY & RIG

(8227)-Wing dihedral, a rigging consideration on most airplanes of conventional design, contributes most to stability of the airplane about its?

• longitudinal axis.

• Vertical axis

• Lateral axis

(8228)-Other than the manufacturer maintenance manual what other document could be used to determine the primary flight control surface deflection for an imported aircraft that is reassembled after shipment?

• 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
