Question 2

Ground spoilers retract via?

Answer 2

• Wheel speed less than 45 knots for at least 5 seconds
• TLA greater than 35 degrees

*Ground spoilers will not work in direct mode

Question 3

Flight Controls are moved via?

Answer 3

Fly-by-wire (FBW) or

Conventional Cables (Ailerons only)

Question 4

High Level Functions for Yaw?

Answer 4

• Yaw damp
• Turn coordination
• Gain on airspeed, as airspeed increases, rudder deflection decreases
