the respective maximum travel positions of the G's

encountered. Depressing the push-to-reset knob at the
lower left corner of the instrument allows the recording
pointers to return to the normal position.
2-85. FREE AIR TEMPERATURE (FAT) GAGE.
The free air temperature gage, mounted outboard

The standby magnetic compass is located below
the overhead fuel management panel and to the right of
the windshield divider. It may be used in the event of
failure of the compass system, or for instrument cross
check. Readings should be taken only during level flight
since errors may
be introduced by turning or acceleration. A compass

Annunciator Panels. Three annunciator panels
are installed. One is a warning panel with red fault
identification lights, and the others are caution/advisory
panels with yellow and green identification lights. The
warning panel is mounted near the center of the
instrument panel below the glareshield (fig. 2-30) and
one caution/ advisory panel is located on the center
subpanel (fig. 2-6). The mission annunciator panel is
located on the copilot's sidewall. Some normal flight
operations involve indications from the mission control
panel (fig. 4-1). Illumination of a red warning light
signifies the existence of a hazardous condition
requiring immediate corrective action. A yellow caution
light signifies a condition other than hazardous requiring
pilot attention. A green advisory light indicates a
functional situation. Table 2-6, 2-7, and 2-8 provides a
list of causes for illumination of the individual
annunciator lights. In frontal view both panels present
rows of small, opaque rectangular indicator lights. Word
printing on each indicator identifies the monitored
function, situation, or fault condition, but cannot be read
until the light J is illuminated. The bulbs of all
