Flight Controls

Question 1

How will the rotor discs react to a right pedal input?

Answer 1

Right pedal input tilts the forward swashplate to the right and the aft swashplate to the left

This movement affects the helicopter’s yaw performance.

Question 2

How will the rotor discs react to a right cyclic input?

Answer 2

Moving the cyclic stick right tilts both the forward and aft swashplates to the right

This input changes the helicopter’s lateral movement.

Question 3

What happens to the collective pitch in the forward and aft rotors when the cyclic is moved forward?

Answer 3

Forward cyclic input decreases thrust in the forward rotor system and increases thrust in the aft rotor system

This causes the aircraft to pitch nose down and increase airspeed.

Question 4

What control movements are required for a hovering turn about the center hook?

Answer 4

Pedal input only

Question 5

What control movements are required for a hovering turn about the forward rotor?

Answer 5

Pedal and cyclic in opposite direction

Question 6

What control movements are required for a hovering turn about the aft rotor?

Answer 6

Pedal and cyclic in same direction

Question 7

What does the abbreviation DAFCS stand for?

Answer 7

Digital advanced flight control system.

Question 8

What does the abbreviation ILCA stand for?

Answer 8

Integrated Lower Control Actuator

Question 9

What does the abbreviation CCDA stand for?

Answer 9

Cockpit Control Driver Actuator

Question 10

What does the abbreviation CPT stand for?

Answer 10

Control Position Transducer

Question 11

Which aircraft system causes the extensible link portion of the ILCA’s to make control inputs?

Answer 11

DAFCS

Question 12

What is the minimum allowable forward cyclic stick travel during the controls check?

Answer 12

7 in FWD

Question 13

What is the minimum allowable aft cyclic stick travel during the controls check?

Answer 13

4 in AFT

Question 14

What are the control limitations for ground operations?

Answer 14

• Thrust – no lower than ground detent
• Lateral cyclic – 1 inch
• Aft cyclic – 2 inches
• Pedals - .75 inches

Question 15

Should you enter forecasted moderate or stronger turbulence with an inoperative thrust brake?

Answer 15

No

Question 16

What environmental flight condition shall be avoided when the thrust brake is inoperative?

Answer 16

Moderate or strong turbulence

Question 17

Which control axes have magnetic brakes that are released when the centering device release switch is pressed?

Answer 17

Pitch, Roll and Yaw

Question 18

Why is it important to have the left and right pedals adjusted to the same holes prior to engine start?

Answer 18

To prevent droop stop pounding

Question 19

What are the functions of the boost portion of the ILCA?

Answer 19

• Provide hydraulic assist from cockpit controls
• Prevent control feedback

Question 20

What is the function of the DAFCS extensible link portion of the ILCA?

Answer 20

Rate dampening
Counteracting environmental conditions

Question 21

How will the forward and aft rotor discs react when the cyclic is moved left?

Answer 21

They will both tilt to the left

Question 22

What are the two parts of the #1 Pitch ILCA?

Answer 22

• Boost
• Extensible link

Question 23

Should you slip the thrust brake during your controls check?

Answer 23

No

Question 24

Pulling the cyclic aft increases pitch in the forward blades and decreases pitch in the aft blades, this is an example of?

Answer 24

Differential Collective Pitch (DCP)

Question 25

What component improves control feel by reducing control sensitivity when the magnetic brake is released?

Answer 25

Viscous Damper

Question 26

What is the purpose of the balance springs on all axes?

Answer 26

To Balance controls around a neutral position

Question 27

What is the preset tilt of the Forward Transmission?

Answer 27

9 degrees

Question 28

What is the preset tilt of the Aft Transmission?

Answer 28

4 degrees
