90 seconds.
• Global positioning system (GPS) altitude
is greater than 600 feet above the
field elevation stored in the terrain database.
Engine Shutdown Inhibit
When either engine is shut down, or its FADEC
determines that the engine has failed, the ESDI
for that engine inhibits some CAS messages
for that engine and related systems. This inhibit
is triggered by FADEC (shutdown indication).
Each FADEC only inhibits messages
from its side.
Emergency Power Mode
To prevent nuisance messages in emergency
power mode, selected messages are inhibited
when the emergency bus is powering the aircraft.
Emergency bus status occurs when:
• The battery switch is in the EMER position,
and
• Both generator bus input discretes have
been lost.
The left GIA and the left GEA receive power
in emergency bus mode. However, most of the
sensors required to indicate CAS messages
are not powered, so most messages have the
EMER inhibit.
Most CAS messages are inhibited in emergency
mode. Some are inhibited to prevent
the flightcrew from being distracted with lowpriority
issues. Other messages are inhibited
because their sources do not receive power in
emergency mode. CAS messages without the
inhibit are listed in Table 4-1.
MASTER INDICATOR LIGHTS
The master indicator lights (red MASTER
WARNING and amber MASTER CAUTION
lights) illuminate to direct pilot attention to
new CAS messages. A MASTER WARNING
and MASTER CAUTION light is on the instrument
panel above each PFD (directly in front
of the pilot and copilot) (Figure 4-5). Each
master indicator light has an integral momentary-
contact pushbutton switch. Pressing the
light resets the light and acknowledges the
CAS message.
NOTE
When the aircraft is first powered
on, any CAS messages that immediately
appear do not cause the master
indicator lights to illuminate. The
CAS considers these messages to be
already acknowledged.
Red MASTER WARNING Lights
When a new red CAS message appears on the
MFD or PFD(s), both red MASTER WARNING

MESSAGE NOTES
GEN OFF L-R Always displays in emergency mode.
ENG CTRL SYS L-R Functions normally since the FADEC receives power from the engine permanent
magnetic alternator (PMA).
FUEL LO INOP L-R Always displayed in emergency mode.
BATTERY O’TEMP Functions normally since the battery temperature monitor does not require
outside power.
BATT TEMP FAIL Functions normally since the battery temperature monitor does not require
outside power.
CABIN ALT Functions normally since the cabin altitude sensor is powered in emergency mode.
Table 4-1. EMERGENCY MODE CAS MESSAGES
Figure 4-5. Master Indicator Lights
lights illuminate flashing. Illumination of the
L–R ENGINE FIRE light(s) also triggers the
MASTER WARNING lights.
Pressing either red MASTER WARNING light
closes the switch momentarily, resetting the
light. This extinguishes the MASTER WARNING
light and stops the CAS message flashing
(the CAS message remains on until the
condition that caused it is corrected).
If a new red CAS message appears in the window,
the MASTER WARNING light flashes
again, and continues flashing until reset. If
two or more red CAS messages are flashing
at the same time, pressing the MASTER
WARNING light once acknowledges them
all at the same time.
If the condition that caused the CAS message
is corrected or stops before resetting the MASTER
WARNING lights, the CAS message and
the red MASTER WARNING lights continue
to flash until acknowledged by resetting the
MASTER WARNING lights. This is to ensure
the important CAS message is seen by the
pilot, even if it is only indicating an intermittent
condition.
Amber MASTER CAUTION
Lights
When a new amber CAS message appears on
the MFD or PFD(s), the amber MASTER CAUTION
lights both illuminate steady.
Each MASTER CAUTION light is an integral
momentary-contact pushbutton switch.
Pressing either MASTER CAUTION light
closes the switch momentarily, resetting the
light, which extinguishes. If a new amber CAS
message appears in the window, the MASTER
CAUTION light illuminates again, and continues
illuminated until reset.
When a MASTER CAUTION light is reset,
both MASTER CAUTION lights extinguish,
and the flashing amber CAS message illuminates
steady until its indicated condition stops
or is corrected. If multiple amber CAS messages
are flashing at the same time, pressing
