INTRODUCTION
The master warning system consists of two master warning lights on the glareshield panel, a
center annunciator panel, five roof annunciator panels, and a system of audible warnings. The
capability to dim and test all annunciators is provided. The system provides a visual and/or au-
dible indication of system status and directs the pilot’s attention to any problem area.
GENERAL
The master warning system (MWS) is de-
signed to include all serious warning indica-
tions on one panel. This panel is located on the
center instrument panel as shown in Appendix
B. Warnings that require immediate crew ac-
tion illuminate red (warning) and cause two red
(MWS) lights on the glareshield to flash.
Pressing the face of either glareshield light will
extinguish both lights and cause the warning
annunciator light to dim. If the fault causing
the annunciator to illuminate is corrected, the

Should the fault not be corrected, the annun-
ciator remains illuminated but at the dimmed
level. Any subsequent problem that illumi-
nates an annunciator causes all annunciators
to come to full brilliance.
The red glareshield lights will not operate when
an amber annunciator illuminates. However,
pressing either one of the MWS lights initiates
the dimming circuit and reduces the intensity
of any illuminated amber annunciator. As with
red warnings, any subsequent caution light
causes the annunciators to come to full bril-
liance if the fault is still in existence.
Indications of less urgency are illuminated in
amber (caution) and are engraved to identify
system association. The lights on the center an-
