I helikoptrar finns ofta en hel del varningslampor vilket det även gör i en R22:a. Dessa lampor ger piloten en indikation om att något inte är okej.

Nedan listar jag de 10 varningslamporna som sitter i Robinson R22 och vad de indikerar.

OIL

Indicates loss of engine power or oilt pressure. Check engine tach for power loss. Check oil pressure gage and, if pressure loss is confirmed, land immediately. Continued operation without oil pressure will cause serious engine damage and engine failure may occure.

MR TEMP

Indicates excessive temperature of main rotor gearbox.

MR CHIP

Indicates metallic particle in main rotor gearbox.

TR CHIP

Indicates metallic particles in tail rotor gearbox.

LOW FUEL

Light comes on when there is approximately one gallon of usable fuel remaining. The engine may run out of fuel after five minutes at cruise power.

CLUTCH LIGHT

Light indicates that the clutch actuator circuit is on, either engaging or disengaging the clutch. When the switch is in the ENGAGE position, the light stays on until the belts are properly tensioned. Never take off before the light goes out.

ALTERNATOR LIGHT

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 the overvoltage relay. If light stays on, land as soon as practical. Continued flight without functioning alternator can result in loss of electronic tachometer, producing hazardous flight condition.

ROTOR BRAKE LIGHT

Light indicates rotor brake is engaged. Release immediatly in flight or before starting enginge.

STARTER-ON LIGHT

Light indicates starter motor is engaged. If light does not go out when ignition switch is released from start position, immediately pull mixture to idle cut-off and turn master switch off. Have starter motor serviced.

GOVERNOR-OFF LIGHT (IF INSTALLED)

Light indicates engine RPM throttle governor is off.

LOW ROTOR RPM LIGHT

Immediately roll on throttle and lower collective. In forward flight also apply aft cyclic. A loud warning horn and an illuminated amber caustion light indicates that the rotor RPM is below safe limits. The horn stops and the amber caution light goes out when RPM is increased to safe limits or when collective control is full down.
