SPOILER SYSTEM
There are four Multi-Functional Spoiler (MFS) panels and two Ground Spoiler (GS) panels located on the upper surface of each wing, just forward of the flaps. MFS and GS position is shown on the EICAS primary and flight control synoptic pages.
A Flight Spoiler Control Lever (FSCL) in the flight compartment is used to control the MFS symmetrically for in flight dumping and provides input to the two FCUs to control the extension/retraction of each MFS panel. Deployment angle is proportional to the position of the FSCL. When the flaps are retracted, all four pairs of MFS are available for lift dumping: with the flaps extended, only the two inboard pairs are used.
The MFS panels provide roll assistance, in flight lift dumping (speed brakes) and ground lift dumping. They are also used as a back-up to the ailerons, in the event of an aileron failure. The MFSs are electrically controlled by the FCUs which actuate hydraulic PCUs, one per surface. The MFSs are hydraulically powered by # 1 and 2 systems. To prevent lift asymmetry, a failed panel will automatically disable the corresponding symmetric panel on the opposite wing.

The GS (most inboard spoilers) deploy on ground only as part of the ground lift dumping function. The GS are controlled symmetrically to either the full extended or full retracted position through hydraulically powered PCUs, one per surface. The GS are hydraulically powered by #1 and 3 systems. Hydraulic supply for PCU operation is provided by an electrically controlled selector valve. Extension of a pair of GS is controlled by energizing two solenoid valves in the selector valve. Retraction occurs as soon as electrical power is removed from one (or both) solenoids which control valve movement.
The GS together with the MFS are used to dump lift and increase drag to assist other braking systems on landing or in the event of a rejected take-off. Each spoiler surface is equipped with one proximity sensor to detect when the surface is retracted. When a proximity sensor indicates a non-retracted surface and no deployment has been commanded, an EICAS message will be displayed on the primary page.

SPOILER SYNOPTIC DISPLAY
The deployment position of all spoilers is shown on the EICAS primary page and flight controls page. When there is no spoiler deployment, all EICAS spoiler icons disappear. Symbology at each spoiler panel display:
