Answer 9

Made of a graphite composite. Controls pitch attitude around the lateral axis (Pitch).

Question 10

Rudder

Answer 10

Made of a graphite composite. Controls flight attitude around the vertical axis (Yaw).

Question 11

What are the secondary flight controls?

Answer 11

Leading edge devices
Trailing edge flaps
Spoiler and speed brakes
Horizontal stab

Question 12

Leading edge devices

Answer 12

Flaps and slats increase wing area and wing camber. Increase lift for takeoff and landing.

Question 13

Trailing edge flaps

Answer 13

Increase wing area and camber. Increase lift for takeoff and landing.

Question 14

Spoiler and speed brake

Answer 14

Help ailerons control roll. supply speed brakes to reduce lift and increase drag during landing.

-Supplies metered brake pressure to stop after landing or rejected takeoff (RTO)

Question 19

What method is used to de-ice the Raked Wingtips?

Answer 19

-Uses electro mechanical expulsive de-icing system which uses electronically powered actuators which gives a pulse to the leading edge and shatter the accrued ice.
