-Wheel speed input above 45 knots or airspeed above 60 knots
-TLA less than 26 degrees
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
Flight Controls are moved via?
Fly-by-wire (FBW) or
Conventional Cables (Ailerons only)
High Level Functions for Yaw?
-Gain on airspeed, as airspeed increases, rudder deflection decreases
Slats/Flaps controlled how?
Electrically controlled, electrically activated.
PDU (Power Driver Unit)- the electric actuators that moves the flaps/slats on their track.
Actuator Control Electronic (ACE)
-The electronic unit controlling the PCU
How many slats?

How many flaps?
4 double-slotted/fowler-type flaps (2 per wing)
First rule in slats/flaps extension or retraction?
