Ground spoilers deploy via?

-WOW
-Wheel speed input above 45 knots or airspeed above 60 knots
-TLA less than 26 degrees

2

Ground spoilers retract via?

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

*Ground spoilers will not work in direct mode

3

Flight Controls are moved via?

Fly-by-wire (FBW) or

Conventional Cables (Ailerons only)

4

High Level Functions for Yaw?

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

5

Slats/Flaps controlled how?

Electrically controlled, electrically activated.

PDU (Power Driver Unit)- the electric actuators that moves the flaps/slats on their track.

6

ACE

Actuator Control Electronic (ACE)

-2 positions

8

How many flaps?

4 double-slotted/fowler-type flaps (2 per wing)
-7 positions

9

First rule in slats/flaps extension or retraction?

Slats extend first, flaps retract first

10

What protects the flaps from an asymmetric condition?

A skew sensor

11
