EMERGENCY PROCEDURES
AutoGyro_POH_Calidus Revision 4.0 – Issue Date 17.JAN.2019 3-9
ROTAX 914 UL: If any of the indicators are permanently lit, switch off all unnecessary
electrical consumers, it is recommended to perform a precautionary landing within 30
minutes. The battery is expected, if in good condition, to provide 30 minutes* of reserve
power to supply the aircraft fuel pump, instrumentation and avionics, after which time
electrical equipment may cease to function and fuel supply to the engine lost. Where the
relay system is installed (see aircraft records), in the event of battery failure the P1 fuel
pump is supplied with electrical power directly from the engine’s internal generator so the
engine may continue to run. However, be prepared for an engine failure.
*depends on capacity of batteries
Further information (914UL)
No power in the cabin indicates either the main circuit fuse has failed, or that the
battery has failed and the pump protection relay (since 09.2013 or retrofitted (UK SB-
073/MC-264)) has opened. In this case the P1 primary fuel pump remains powered by
the regulator directly, maintaining fuel supply to the engine. The turbo control unit is
not powered in this instance, and will remain in whatever position it was in when
power was lost – so mixture and manifold pressure control will be lost. Take care to
only use the minimum power required to land safely to prevent engine damage.
In this case the primary fuel pump will continue to run until the engine alternator
stops providing electrical energy. If required, fuel supply can be shut off via the fuel
shut-off valve.
NOTE
A gently pulsing GEN indicator light (visible in low light conditions and
depending on date of manufacture) is normal and indicates proper function of
the generator.
3.13.2 Low Volt
Battery voltage of the system has dropped below a safe value. Refer to chapter above.
Non-essential services and the 12V power receptacle will be disabled automatically.
3.13.3 BOOST WARN Light ‘Boost’ (red) - only ROTAX 914 UL
Continuously lit
If continuously lit, the maximum admissible boost pressure was exceeded. Reduce power
into normal operating range and consider restricted engine performance or boost control
malfunction. Record duration and have maintenance action performed.
Blinking
When blinking, the allowable 5 minutes take-off power time limit has been exceeded.
Reduce power into continuous range. Record duration and have maintenance action
performed.
