Airframe Oral Ch. 1 Structure Assembly And Rigging

Front 1

What is the function of a Vortex generator

Back 1

It is designed to delay or prevent separation of the boundary air.

Front 2

What are the three axes of an airplane

Back 2

Longitudinal, lateral and vertical

Front 3

What are the three primary flight controls on an aircraft

Back 3

Ailerons, elevator and rudder

Front 4

Name several secondary flight controls and describe their general purpose

Back 4

Secondary flight controls consists of various types to trim tabs such as balance tabs, anti Servo and Servo tabs, and spring tabs. Their function is to assist the pilot and moving the controls and to trim the aircraft to fly hands off

Front 5

Name several types of auxiliary flight controls and describe their general purpose

Back 5

The axillary flight controls consists of the various high lift devices used during low-speed flight such as leading and trailing Edge flaps, slats, alots, speed brakes, etc.

Front 6

What is a Servo trim tab

Back 6

It is auxiliary control, positioned by the movement of a cockpit control and designed to create aerodynamic forces to assist in moving a control surface

Front 7

What is a spring tab

Back 7

It is an auxiliary control designed to Aid the movement of a primary control at high speeds when control forces become too high

Front 8

What is a balance trim tab

Back 8

It is an auxiliary control designed to create aerodynamic forces to assist in moving a control surface. The tab is positioned by a control rod connected to the fix surface on the same side as the horn on the tab

Front 9

What are four most and common types of high lift devices

Back 9

Leading and trailing Edge flaps, slats, and slots

Front 10

Describe some of the tools used to check control surface travel

Back 10

Are Universal propeller protractor or special control surface protractor

Front 11

Name three mechanical methods by which flight Control Systems may be actuated

Back 11

Cables, push-pull rods, and torque tubes.

Front 12

What is a fairlead

Back 12

It is a device to prevent a cable from rubbing on an aircraft structure

Front 13

What are the most likely places for a control cable to wear or break

Back 13

Where the cables Passover pulleys or through fairleads

Front 14

What information is required before a cable rigging chart can be used

Back 14

The ambient temperature and the cable size

Front 15

What is the function of a cable tension regulator

Back 15

It automatically adjust the cable tension to compensate for expansion and contraction in the aircraft structure

Front 16

Describe the function of a rotorcraft collective pitch control

Back 16

The collective control causes each rotor blade to change its pitch angle by the same amount thus increasing or decreasing the lift produced by the rotor

Front 17

Describe the function of a rotorcraft cyclic pitch control

Back 17

The cyclic control tilts the main rotor disc by changing the pitch angle of each rotor blade during its cycle of rotation, which causes the helicopter to move in the direction the rotor tilts

Front 18

What mechanism is most commonly used to compensate for the torque produced by the main rotor of a helicopter

Back 18

The tail rotor

Front 19

How is the amount of thrust produced by a tail rotor controlled

Back 19

By moving the foot pedals

Front 20

Why should control surfaces be locked when an aircraft is parked

Back 20

To prevent damage from the wind
