SECTION3
EMERGENCY PROCEDURES
If the alternator and battery ammeters continue to indicate alternator
failure, or' if the alternator will not remain reset, turn off the ALT switch,
maintain minimum electrical load and land as soon as practical. All electrical
load is being supplied by the battery. The Low Bus Voltage annunciator will
illuminate as battery power is depleted.
3.27 ELECTRICAL OVERLOAD (alternator over 20 amps above known
electrical load)'
If abnormally high alternator output is observed (more than 20 amps
above known electrical load for the operating conditions) it may be caused
by a low battery, a battery fault or other abnormal electrical load. If the cause
is a low battery, the battery charge indication should begin to decrease
toward normal within 5 minutes. If the high battery charge load persists,
turn the battery master switch OFF and land as soon as practical. All
electrical loads are being supplied by the alternator.
If the electrical overload condition is present and the battery charge
load is normal, turn the alternator OFF and reduce the electrical loads to a
minimum. Battery power should be used only as required and the flight
should be terminated as soon as possible. If battery power is required for
flight, the Low Bus Voltage annunciator light will illuminate as battery
power is depleted. Complete electrical failure is possible if prolonged
battery power usage is required.
NOTE
Due to higher voltage and radio frequency
noise, operation with the ALT switch ON and
the BAT switch OFF should be made only when
required by an electrical failure.
NOTE
If the battery is depleted, the landing gear must
be lowered using the emergency extension
procedure. The gear position lights and flaps will
be inoperative.
