➢
Rotax 912ULS
If GEN warning is alight, switch off all unnecessary electrical systems and land at the
nearest place. The battery is expected, in good condition, to provide 15 minutes of
reserve power to supply the aircraft instrumentation, avionics and fans, after which
time electrical equipment may cease to function. If maintaining translation flight, Oil T°
and Coolant T° may continue to show nominal values.
➢
Rotax 912ULS-I (injection system)
If GEN warning is alight, the battery is expected, in good condition, to provide 15min
of reserve power to supply the aircraft fuel pumps, instrumentation, avionics and fans,
after which time electrical systems, including fuel pumps may cease to function Be
prepared for an engine failure.
➢
Rotax 914UL (turbo)
If GEN warning is alight, switch off all unnecessary electrical systems and land at the
nearest suitable place. The battery is expected, in good condition, to provide 15min of
reserve power to supply the aircraft fuel pumps, instrumentation, avionics and fans,
after which time electrical systems, including fuel pumps, may cease to function. The
TCU (Turbo Control Unit) will not be powered anymore and will remain in whatever
position it was when power was lost
– so mixture and manifold pressure control will
also be lost. Take care to use minimum power required to land safely to prevent engine
damage.
CAUTION
The Rotax 914UL (turbo) is fed by two electrical fuel pumps. The engine is
controlled by a Turbo Control Unit (TCU). The probability of an electrical failure
is of a very low order but any failure can cause the engine to stop.
The Rotax 912ULS-I (injection system) is fed by two electrical fuel pumps. The
engine is controlled by an Engine Control Unit (ECU) and is fuel injected. Various
sensors send permanent data to the ECU. The probability of an electrical failure
is of a very low order but any failure can cause the engine to stop.
Low RPM rotor (White) + Audio alarm
➢
Lower the collective and override the governor with the throttle grip to recover
rotor RPM immediately.
➢
If you are close to terrain and can not recover RPM by opening the throttle, land
at the nearest suitable spot.
CAUTION
