DC power distribution system
The function of the DC power distribution
system is similar to the AC system in that the
right and left system function separately. The
DC system has a manual crosstie in the
event of a failure of either side. In addition to
the left and right systems, DC power is
supplied from the battery.
Batteries
Two 14 volt batteries are connected in series
to supply 28 volt DC power. The battery is
automatically being charged when
electrical power is on the aircraft and the
battery switch is ON. When operating on
emergency power, the batteries should last
for 30 minutes.
Battery charger
The battery charger is operative when the
aircraft power is on, and the battery switch is
in the ON position. When the battery is fully
charged, the battery charger will be in a
pulsating mode. If the battery is in a low
state of charge, the ammeter will indicate a
continuous current of approximately 65
amperes, and then switch into a pulsating
mode as the battery becomes fully
charged.
