41
Q

When a fault is detected in a Yaw Damper controller, the INOP light illuminates and L or R YAW DAMPER EICAS msg displays. What happens to the faulty controller and yaw damper authority?

49
Q

What 3 functions do the spoilers perform?

A

The spoilers are used to perform three functions:

Act as in-flight speedbrakes to increase drag and reduce lift

Supplement and assist the ailerons with roll control

Operate as speed brakes during landing rollout

50
Q

SPEED BRAKES caution light and SPEED BRAKES EICAS msg displays when the speedbrakes are extended and (2)

With the SPEEDBRAKE lever in ARMED, the spoilers will deploy when the following three conditions are met:

Hydraulic pressure exists in both landing gear truck tilt actuators

Both truck tilt actuators detect a no-tilt condition (aircraft on the ground)

Both thrust levers are at idle

The speedbrakes will also deploy regardless of the lever position if the above conditions are met and reverse thrust is selected for either engine

A

The speedbrakes will automatically retract once any of the following conditions no longer exist:

Hydraulic pressure exists in both landing gear truck tilt actuators

Both truck tilt actuators detect a no-tilt condition (aircraft on the ground)

Both thrust levers are at idle

Q

Flap gates exist at what two flap settings?

A

There are two flap gates installed at:

FLAPS 1 to prevent inadvertent retraction of the slats

FLAPS 20 to prevent inadvertent retraction of the flaps past the go-around position

Q

Do trailing edge flaps extend when FLAPS 1 is selected?

A

The slats are signaled to extend to the midrange position while the flaps remain retracted.

The pointers on the flap position indicator move midway between UP and 1 while the slats are in transit.

The pointers move to 1 when all slats reach the midrange position.

Q

For flaps 5, 15 and 20, what positions do the leading edge slats maintain?

A

The leading slats remain in the midrange position.
