FOR TRAINING PURPOSES ONLY
A start inhibit facility prevents engine start-
ing while the EXT BATT CHG switch located
on the pilot’s roof panel is set to ON.
NOTE
With the BATT switch on and ground
power plugged in, selecting START
PWR on first causes the EXT PWR
switch to be ineffective.
DISTRIBUTION
Distribution of electrical power is made via a
main distribution panel DA located just aft of
the copilot’s seat. The panel embodies two gen-
eral service circuit-breaker panels (Figures 2-
21 and 2-22) and one circuit-breaker panel for
avionics, navigation, and radio services.
The general-service circuit breakers on the
subpanel DA-D and DA-A are identified by la-
bels showing the systems and a grid. The grid
is marked in numbers horizontally and letters
v e r t i c a l l y. C i r c u i t b r e a k e r s p r o t e c t i n g
unswitched PE systems are marked with a
white background for ease of isolation in the
event of smoke or fire. The push-pull button
of each circuit breaker is marked with the ap-
propriate ampere rating.
The DC bus bar system also includes three
panels in the rear equipment bay area. These
panels contain circuits and fuses for certain es-
sential services. A negative ground return is
provided through the airplane structure via
grounding points below the panels in the equip-
ment bay.
Nonessential systems which are duplicated, or
where the load is divisible, are supplied from
bus bar PS1 or PS2 so that a power supply
failure on either bus bar will not result in a
complete failure of these systems. Nonessen-
tial systems which are not divisible are sup-
plied from either PS1 or PS2. All essential
systems are supplied from bus bar PE.
OPERATION
If a ground power supply is available, check
that the plug is in firmly. The ground power
unit must be fitted with a current limiter op-
eration at 1,100 amperes.
Before starting the external inspection, carry
out a preliminary check in the flight com-
partment. Switch on the entry light if re-
quired and confirm that the fire extinguisher
switches are off and that all circuit breakers
are in. If ground power is not connected, set
the EXT BATT CHG switch to OFF, the EXT
PWR switch to OFF, and the BATT switch to
ON. With ground power connected, leave
