43
Q

If forward thrust is applied after speedbrakes have been automatically deployed on landing, which answer is correct?

A

All spoiler panels retract and the speed brake lever moves to the down detent.

44
Q

What protection is provided to prevent uncommanded motion in the Leading Edge devices during cruise?

A

Positive hydraulic pressure on the retract lines and depressurization of the extended full extend lines.

45
Q

During Autoslat operation, which Leading Edge devices are extended?

A

Just the leading-edge slats.

Q

The stabilizer trim motor may be stopped by firmly holding either manual trim wheel and preventing it from moving, true or false?

True

47
Q

At what trailing-edge flap position with a leading-edge slats move to the full extent position?

A

Greater than flaps 5

A

Activation of the stabilizer trim system.

49
Q

Does the power transfer unit use system A or B to power system A or B, and for what purpose?

A

The PTU system uses system A fluid to power the PTU for the auto slat and Leading Edge device operation if system B engine hydraulic pump volume is lost ( the pressurizes the remaining B-side fluid.)

Which indication would be correct if the FSEU (flap/slat electronic unit) has detected a trailing-edge flap asymmetry condition?

A

The flap indicator pointers are split.

60

Extend

61
Q

Which hydraulic system(s) power the flight spoilers?

Flight spoilers

63
