Assembly & Rigging M1

(8245) The purpose of wing slats is to

• reduce stalling speed.

• decrease drag.

• reduce lift.

(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.

(8248) Movement of an airplane along its lateral axis (roll)

is also movement

• around or about the longitudinal axis controlled by the elevator.

• around or about the lateral axis controlled by the ailerons.

• around or about the longitudinal axis controlled by the ailerons.

(8249) The primary purpose of stall strips is to

• provide added lift at slow speeds.

• stall the inboard portion of the wings first.

• provide added lift at high angles of attack.

(8257) The vast majority of aircraft control cables are

terminated with swaged terminals, that must be

• corrosion treated to show compliance with the manufacturer's requirements after the swaging operation.

• pull tested to show compliance with the manufacturer's requirements after the swaging operation.

• checked with a go-no-go gauge before and after, to show compliance with the manufacturer's requirements after the swaging operation.

(8258) What nondestructive checking method is normally used to ensure that the correct amount of swaging has taken place when installing swaged-type terminals on aircraft control cable?

• Check the surface of the swaged portion of the terminal for small cracks which indicate incomplete swaging.

• Measure the finished length of the terminal barrel and compare with the beginning length.

• Use a terminal gauge to check the diameter of the swaged portion of the terminal.

(8261) Which is an acceptable safety device for a castle nut when installed on secondary structures?

• Star washer.

• Lockwasher.

• Cotter pin.

(8262) When used in close proximity to magnetic compasses, cotter pins are made of what material?

• Corrosion resisting steel.

• Anodized aluminum alloy.

• Cadmium-plated low carbon steel.

(8264) The purpose of the vertical fin is to provide

• directional stability.

• longitudinal stability.

• lateral stability.

(8265) How are changes in direction of a control cable accomplished?

• Pulleys.

• Bell cranks.

• Fairleads.
