INDICATIONS
When electrical power is initially provided, or
the mode selector switch is moved to auto
from manual, the computerized controller per-
forms a self-test which, if successful, illumi-
nates the amber FAULT and AUTO FAULT
lights for two seconds only.
A dual-scale, three-needle indicator (Figure
12-2) on the copilot's side panel provides si-
multaneous indication of (1) cabin altitude in
thousands of feet, (2) cabin atmosphere-dif-
ferential pressure in psid, and, when applica-
ble, (3) cabin rate of change up or down in feet
per minute times 1,000. The cabin altitude

needle is labeled "ALT," and the cabin differ-
ential pressure needle is labeled "PSI." Both
indicate on the same scale. The cabin rate-of-
change needle indicates on the left scale and
the needle is not labeled.
An amber light labeled "CABIN PRESS LOW"
on the pressurization control panel (Figure
12-1 and Annunciator Panel Section) is oper-
ated from an aneroid switch behind the panel.
The light will illuminate if the cabin altitude
exceeds approximately 10,400 feet. In addi-
tion, the NO SMOKING, SEAT BELTS, and
ENVironmental CONTrol annunciators will il-
luminate, and the MASTER CAUTION lights
(Annunciator Panel Section) will flash.
