- off.
(navigation, strobe, taxi, landing lights etc.).

Restrict / avoid use of the elevator trim control. Restrict radio
transmission to minimum / only that which is absolutely necessary.
10.
Land as soon as possible.
NOTE
When landing with adequate battery power remaining (to power both the
propeller motor and the fuel pump(s)) the propeller can be re-energized and
selections made as applicable. The
auxiliary fuel pump is switched off / verified to
be off to conserve battery charge. If required, the auxiliary pump can still be
operated from the main bus provided that the master switch is on, there is no
failure of power supply to the main bus and the charge system relay remains
energized / is not failed
.
WARNING
The engine will continue to run after an alternator failure, until the
battery voltage is low (approximately 30 minutes if all ancillary
equipment is switched off and provided that the battery was fully
charged at the time of alternator failure). The engine will cease
running due to fuel starvation (due to electrical pump(s) stopping)
when the battery is depleted.
