Question 4

What are the three primary flight controls of an A/C?

Answer 4

Ailerons, elevator and rudder

Question 5

What is flutter?

Answer 5

When an out of balance condition causes control surfaces to oscillate in the airstream, often leading to catastrophic failure of the structure.

Question 6

Primary flight control systems control the aircraft along three axes of rotation, what are they?

Answer 6

Lateral (pitch axis)- uses the elevators to pitch up and down.
Longitudinal (roll axis)- uses ailerons to bank the wing causing the airplane to turn.
Vertical (yaw axis)- uses the rudder to improve quality of turns

Question 7

What are the four main types of flaps?

Answer 7

Plain, split, slotted and fowler

Question 8

What prevents contact between a control cable and the aircraft structure to prevent wear on the cables and structures?

Answer 8

Fairleads

Question 9

What are tensiometers?

Answer 9

Measuring device used to check the tension of aircraft control cables.

Question 10

What provides the ability to change the direction of travel of the surface?

Answer 10

Push pull rods connected to cable-driven bell cranks to control surfaces

Question 11

What is a turnbuckle?

Answer 11

A type of fastener that enables you to adjust cable tensions

Question 12

What is the fixed horizontal tail surface?

Answer 12

Horizontal stabilizer

Question 13

What is a movable horizontal tail surface called?

Answer 13

Elevator

Question 14

When the control wheel of the A/C is pulled back, what does the trailing edge of the elevator do?

Answer 14

Elevator moves upward

Question 15

If a pilot pushes the control yoke forward, the trailing edge of the stabilator will move?

Answer 15

Downward

Question 16

To bank an airplane to the right, the aileron on the right wing moves?

Answer 16

Upward

Question 17

What do many airplanes use to compensate for aileron drag?

Answer 17

Rudder-aileron interconnect springs

Question 18

Depressing the right rudder pedal will move the trailing edge of the rudder to the?

Answer 18

Right

Question 19

What is a trim tab?

Answer 19

A secondary control surface used to correct out of trim conditions

Question 20

What direction does a balance tab move?

Answer 20

Opposite direction of the control surface it is attached to

Question 21

Which direction does the anti-servo tab move?

Answer 21

Same direction as the control surface it is attached to

Question 22

A servo tab moves in the direction as the control surface to which it is attached.

Answer 22

Opposite

Question 23

Moving the leading edge of an adjustable stabilizer up, trims the airplane nose?

Answer 23

Down

Question 24

What type of flaps are used to prevent airflow from breaking away from the upper surface when the flaps are fully extended?

Answer 24

Slotted

Question 25

What is a fowler flap?

Answer 25

A flap that rides out of the trailing edge of the wing on the tracks and increases the wing area as well as it's camber

Question 26

A fixed ducts air over the top of the wing to keep the aileron effective and provides lateral control during stall.

Answer 26

Slot

Question 27

What do hydraulically boosted control systems use to prevent control surface buffeting from being fed back to the pilot?

Answer 27

Irreversible inputs

Question 28

Strand number designation for each type of cable: Flexible Extra-flexible Non-flexible

Answer 28

7*7 7*19 1*7 or 1*19

Question 29

A/C cables should be carefully inspected for what two defects?

Answer 29

Corrosion and wear

Question 30

During a proof load-test what breaking strength should a cable be subject to?

Answer 30

60% of it's breaking strength for three minutes

Question 31

True or false, Fairleads may be used to change the direction of a cable.

Answer 31

False

Question 32

How many threads can be exposed at either end of the barrel for a turnbuckle to reach its full strength?

Answer 32

Three threads

Question 33

When safety-wiring a turnbuckle, how many full wraps of wire should be around the shank before cutting?

Answer 33

Four full wraps

Question 34

Using the cyclic pitch control mounted between the pilots legs, the helicopter tilts which direction?

Answer 34

In the direction the cyclic stick moves

Question 35

The collective pitch control causes the helicopter to move in which direction?

Answer 35

Vertically

Question 36

The control that changes the pitch on all rotor blades at the same time is called?

Answer 36

Collective pitch control

Question 37

Boosted controls on a helicopter cannot feed vibrations back through the controls if?

Answer 37

Irreversible control system is used
