Spoiler Indications - BOMBARDIER LEARJET 40 Pilot's Manual

SPOILER INDICATIONS

Spoiler extension is indicated at the base of either the SUMRY or FLT
system schematic page on either EICAS or MFD. On the FLT system
schematic display, spoiler extension is presented as a digital display
and as a vertical analog scale with dual points (one for each spoiler).
The digital displays on the SUMRY and FLT pages only show spoiler
extension commanded by autospoilers or with the spoiler lever. They
do not reflect differential extension resulting from operation in
spoileron mode. When the airplane is on the ground with spoilers
extended, a white box will overlay the digital spoiler display. If power
is advanced for takeoff with either or both spoilers extended, this
digital display and box will turn red along with the pointers on the an-
alog scale. In addition, a red CAS and "CONFIGURATION" voice mes-
sage will activate. Spoilers should not be extended at the same time
flaps are extended while in flight except as specified in the Airplane
Flight Manual, or the following CAS message will be posted.
The following CAS illuminations are specific to the spoilers:

The analog scale and pointers are real time showing actual spoiler
position for all conditions. When spoilers are extended as result of
spoileron operation, pointers will indicate their differential on the
analog scale. Digital spoiler indicators and analog scale pointers will
turn amber when flaps are extended 3° or more with spoilers extended.
PM-132A
Color
Red The spoilers have moved from the stowed
position, with aircraft on the ground, and
either thrust lever is advanced to MCR or
above.
Amber The aircraft is in flight and spoilers are
extended with flaps extended more than 3°.
White Spoilers are not fully retracted. Spoileron
extension will not activate this CAS (flight and
ground).
