For example,
1. Gauge suddenly goes to full scale deflection, other gauges reading normally –
likely gauge fault
2. Oil pressure falls to zero, possible loss of pressure. Stop engine, make
precautionary landing
3. Water temp gradually or suddenly rises above max temp. Possible loss of
coolant. Stop engine, make precautionary landing
4. Oil temp suddenly falls to zero, other gauges reading normal – probable gauge
failure.
5. Oil temp rises above maximum, other gauges normal – possible very low oil level,
blocked radiator or thermostat. Stop engine, make precautionary landing.
6. Fuel level gauge suddenly falls to zero or FSD. Probable gauge failure, but
always cross check to predicted fuel burn. Low fuel light will light as a backup.
Sudden large deflections are normally unlikely, with the exception of loss of pressure
readings.
3.13 Warning Lights
3.13.1 GEN (orange) or Low Volt (orange) Indicator Light
The GEN lamp, when lit, indicates that there is no voltage being supplied from the
regulator circuit to the battery. The Gen2 lamp (if fitted), when lit, indicates that there
is no voltage being supplied from the external generator to the battery.
Both are normally lit when the engine is stationary or at very low rpm.
These lamps are normally not lit in flight, but may be seen to pulse gently in low light
conditions.
If the GEN and GEN2 lamps and the LOW VOLT lamp are on with the engine running at
more than 2,500rpm, then it is likely that the charging circuits have failed, and that the
aircraft is operating on battery power alone.
If only the LOW VOLT lamp is lit, then the aircraft voltage demand has exceeded supply,
and demand must be reduced in order for the lamp to extinguish. NOTE! When lit, this lamp
also indicates that the strobes, nav lights, anti-collision lights and 12v socket have been
turned off automatically, with automatic reconnection when the supply exceeds demand.
If only the LOW VOLT lamp is lit, then the aircraft voltage demand has exceeded supply,
and demand must be reduced in order for the lamp to extinguish. NOTE! When lit, this lamp
also indicates that non-essential services and 12v socket (where fitted) have been turned off
automatically, with automatic reconnection when the supply exceeds demand.
Required Action
ROTAX 912 ULS: If any of the indicators are permanently lit, switch off all unnecessary
electrical consumers and land at the nearest airfield where maintenance can be performed.
The battery is expected, if in good condition, to provide 30 minutes* of reserve power to
supply the aircraft instrumentation and avionics, after which time electrical equipment may
cease to function.
