Airframe O&p (1.ac Structural Assembly And Rigging)

Front 1

What is the function of a vortex generator (VG)?

Back 1

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

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 of an aircraft?

Back 3

The ailerons, elevator, and rudder

Front 4

Name several secondary flight controls tools and describe their general purpose?

Back 4

Secondary flight controls consist of various types to trim tabs such as balance tabs. Antiservo and servo tabs and spring tabs. Their function is to assist the pilot in 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 auxiliary flight controls consist of the various high-pitched devices used during low-speed flight such as leading and trailing edge flaps, slats, slots, speed brakes, etc.

Front 6

What is a servo trim tab?

Back 6

It is an 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 fixed surface on the same side as the horn on the tab.

Front 9

What are the four most 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

A universal propeller protractor or special control surface protractor

Front 11

Name 3 mechanical methods by which flight controls systems may be actuated

Back 11

Cables, push rods, torque tubes

Front 12

What is a fairlead?

Back 12

It is a device to prevent a cable from rubbing ok new the aircraft structure

Front 13

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

Back 13

Where the cables pass over pulleys or through fairleads

Front 14

What information is required before a cable and 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 adjusts the cable tension so 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 cause the helicopter to move in the direction of 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 (or anti-torque) rotor

Front 19

How is the amount that of thrust produced by the tail rotor controlled?

Back 19

By moving the foot pedals

Front 20

Why should control surfaces be Mocksville when an aircraft is parked

Back 20

To prevent damage from the wind.
