The flat position indicator will show pointer movement.
If forward thrust is applied after speedbrakes have been automatically deployed on landing, which answer is correct?
All spoiler panels retract and the speed brake lever moves to the down detent.
What protection is provided to prevent uncommanded motion in the Leading Edge devices during cruise?
Positive hydraulic pressure on the retract lines and depressurization of the extended full extend lines.
