3.3.10 ALTERNATOR FAILURE
If the alternator fails, the electrical system will run on a fully charged
battery for about 0.75 hours. However, it would be prudent and highly
advised to land and resolve the problem as soon as practical. Some
equipment when operated at low RPM may give a warning of battery
discharge which should disappear with higher power settings. This
equipment includes landing gear re-positioning linear actuators or even a
long radio communication at idle power. This is normal and expected and
is transient in nature. CAUTION: Battery or other electrical power is
required for operation of the fuel pumps for Rotax 914 engines.
3.3.10.1 IF LOW VOLTAGE LIGHT ILLUMINATES AGAIN
All Non-essential
Equipment
3.3.10.2 OVERVOLTAGE
There is an over-voltage protection circuit that will interrupt the alternator
feed automatically. If this happens the aircraft will draw on battery alone
until a low voltage condition is experienced. Use the EFIS to reset the
over-voltage condition, and the alternator will again be connected which
may restore normal power or may again result in an automatic disconnect
of the alternator. Terminate flight.
3.3.11 INADVERTENT SPIN
FULL OPPOSITE to direction of spin
Progressively forward until rotation ceases
