Warn.10 Warning and Alerting-Description and Operation
General
Warning and alerting consists of Electronic Instrument System (EIS), Central
Aural Warning System (CAWS), and Ground Proximity Warning System
(GPWS).
Electronic Instrument System (EIS) Alerting
The EIS alerting system displays alerts on the CRTs in the cockpit.
The system also displays the consequences, if any, of the alerts. The EIS alerting
system consists of:
• MASTER WARNING and MASTER CAUTION lights (MW/MC).
• The Engine and Alert Display (EAD).
• The System Display (SD).
• The System Display Control Panel (SDCP).
Alerts are categorized into four levels (3, 2, 1, and 0). Alert levels have unique
display characteristics to allow immediate crew recognition of the alert level.
Alerts are presented in three columns in the lower 1/3 of the EAD. Each column
allows alerts up to 17 characters long, including leading triangles for level 3 alerts.
The first two columns may contain 6 alerts, but the third column is limited to only
4 because the two bottom lines are dedicated for reminder messages.
The EAD alerts are filtered. Only the root cause alert will be displayed. Additional
alerts which occur as a result of the initial failure are inhibited.
Pushing the associated system cue switch on the SDCP will cause the associated
system synoptic page to be displayed on the SD and also resets the MASTER
CAUTION or MASTER WARNING lights if they are illuminated and no other
lights are illuminated.
On any SD page a PRESS (associated cue switch) AGAIN TO CONTINUE
message tells the pilot that alerts or consequences on subsequent SD pages can be
accessed by pushing the associated cue switch. The associated cue switch part of
the message flashes until all pages have been reviewed. The secondary engine
page automatically appears on the SD for alerts associated with the secondary
engine page parameters (see Engines chapter).
