INDICATIONS
The cabin temperature is presented as a digi-
t a l r e a d o u t i n t h e t o p l e f t c o r n e r o f t h e
schematic, and the cabin supply duct temper-
ature is presented as the left half of the ana-
log tape with pointer display. The cockpit
temperature is not displayed, but the cockpit
supply duct temperature is presented as the
right half of the analog display. The analog
CAB/CKPT temperature display range is from
30° F, the bottom tick-mark, up to 300° F, the
top tick-mark. Each index mark on the scale
represents 90 degrees.
As depicted in Figure 11-6 the analog supply
temperature scale is white with white point-
ers. If the duct temperature exceeds 300° F, the
pointers turn amber. Should an invalid tem-
perature be reported to the Integrated ECS
Temp Controller, each pointer is replaced with
a red “X.” Should an invalid cabin tempera-
ture be received, the digital display is replaced
with amber dashes.
