Spoiler deployment is shown on both the WHEEL page and the F/CTL page.
Spoiler control is shared by the PRIM and the SEC computers.
Extension is inhibited when:
If an inhibition occurs with speedbrakes extended, they automatically retract until the inhibition disappears and the lever is reset.
The ground spoilers should be armed manually for takeoff and landing. Deploy when:
Partial extension occurs when:
Automatic retraction occurs when:
A servojack positions each spoiler.
Spoilers are generally automatically retracted when faulty or not electrically controlled. If the hydraulic system controlling the spoiler actuator is lost, the affected spoiler remains at its current deflection unless pushed down by aerodynamic forces.
F/CTL SPLR FAULT | - the failed spoiler is shown as Δ - the symmetrical one on the other wing is automatically inhibited, except for spoilers 4 and 6 |
