Warning and Caution Lights Note

If light causes excessive glare at night, bulb may be unscrewed or circuit breaker pulled to eliminate glare during landing.

Oil Warning/Caution Light

Indicates loss of engine power or oil pressure. Check engine tach for power loss. Check pressure gauge, and if pressure loss is confirmed land immediately. Continued flight without oil pressure will cause serious engine damage or engine failure may occur.

MT Temp Caution/Warning Light

Indicates excessive temperature of main rotor gearbox.

MR Chip Caution/Warning Light

Indicates metallic particles in main rotor gearbox.

TR Chip Caution/Warning Light

Indicates metallic particles in tail rotor gearbox.

Note for Chip Lights

If light is accompanied by any indication of a problem, such as noise, vibration, or temperature rise, land immediately. If there is no other indication, land as soon as practical.

Low Fuel Light

Indicates approximately one gallon of usable fuel remaining for all-aluminum fuel tanks or 1.5 gallons for bladder-style tanks. The engine will run out of fuel after approximately five minutes at cruise power for aircraft with all-aluminumtanks or ten minutes with bladder-style tanks.CAUTIONDo not use low fuel caution light as a working indication of fuel quantity.

Clutch Light

Indicates clutch actuator circuit is on, either engaging or disengaging clutch. When switch is in the ENGAGE position, light stays on until belts are properly tensioned. Never take off before light goes out.NOTEClutch light may come on momentarily during run-up or during flight to retension belts as they warm-up and stretch slightly. This is normal. If, however, the light flickers or comes on in flight and does not go out within 10 seconds, pull CLUTCH circuit breaker and land as soon as practical. Reduce power and land immediately if there are other indications of drive system failure (be prepared to enter autorotation). Inspect drive system for a possible malfunction.

ALT Light

Indicates low voltage and possible alternator failure. Turn off nonessential electrical equipment and switch ALT off and back on after one second to reset overvoltage relay. If light stays on, land as soon as practical. Continued flight without functioning alternator can result in loss of electronic tachometer, producing a hazardous flight condition.

Brake Light

Indicates rotor brake is engaged. Release immediately in flight or before starting engine.

Starter-On Light

Indicates starter motor is engaged. If light does not go out when ignition switch is released from start position, immediately pull mixture off and turn battery switch off. Have starter motor serviced.

GOV Light

Indicates engine RPM throttle governor is off.

Carbon Monoxide (if installed) Light

Indicates elevated levels of carbon monoxide (CO) in cabin. Shut off heater and open nose and door vents. If hovering, land or transition to forward flight. If symptoms of CO poisoning (headache, drowsiness, dizziness) accompany light, land immediately.

Full Throttle (if installed) Light

Indicates engine near full throttle. The governor will be ineffective because it cannot increase throttle to maintain RPM. Lower collective as required to extinguish light.

Low RPM Horn and Light

A horn and an illuminated caution light indicate that rotor RPM may be below safe limits. To restore RPM, immediately roll throttle on, lower collective and, in forward flight, apply aft cyclic. The horn and caution light are disabled when collective is full down.

Right Roll in Low G Condition

Gradually apply aft cyclic to restore positive G forces and main rotor thrust. Do not apply lateral cyclic until positive G forces have been established.

Uncommanded pitch, roll, or yaw resulting from flight in turbulence.

Gradually apply controls to maintain rotor RPM, positive G forces, and to eliminate slip slide. Minimize cyclic control inputs in turbulence; do not over control.

Inadvertent encounter with moderate, severe, or extreme turbulence.

If the area of turbulence is isolated, depart the are; otherwise land the helicopter as soon as practical.
