IV. ENGINE CHIP- Illuminates when the magnetic trap in the engine oil system

detects particles of metal. Indicative of moderate to serious engine wear.

V. BATTERY HOT - Indicates that the battery temperature has reached 140 degrees,

usually during repeated start attempts. If the engine is not running then the battery

should be switched off and be left for several minutes to cool down.

VI. TRANS OIL PRESS - Illuminates when transmission oil pressure is below

approximately 30 PSI and is normally lit prior to and during the first few seconds of

the engine start procedure.

VII. ENG OUT – Indicates that Gas Producer (N1) turbine speed is below the self-

sustaining limit of 58% and is normally lit until the starter can be released during a

start procedure. Also illuminates if the engine fails in flight and N1 speeds drops

below 58%. The light is accompanied by a siren sound when the CAUTION LT CB

is in.

VIII. FUEL LOW - Illuminates if fuel volume is below 20 US Gallons.

IX. FUEL PUMP - Illuminates if either fuel pump CB is out or either pump has failed.

X. T/R CHIP - Indicates that the magnetic trap in the tail rotor transmission gearbox

has detected metal particles, indicating considerable wear and the possibility of an

impending tail rotor transmission failure.

XI. TRANS CHIP - Indicates that the magnetic trap in the main transmission gearbox

has detected metal particles, indicating considerable wear and the possibility of an

impending main transmission, (“sprag” clutch), failure.

XII. BATTERY TEMP - Illuminates when battery temperature exceeds 130 degrees.

May ordinarily light during a start attempt but should go out soon after.

XIII. TRANS OIL TEMP – Indicates that transmission oil temperature is above the

normal operating limit of 110 °C and is indicative of considerable wear. A main

transmission failure may be imminent.

XIV. ROTOR LOW RPM - Illuminates when rotor RPM (NR) drops below 90% normal

flight speed. The light is accompanied by a horn sound when the circuit CB is in

and the collective lever is above its bottom stop.

XV. SC FAIL – This annunciator is special in that it utilises the top left spare position

and illuminates, (flashes), only when the software has detected that FSX’s

SimConnect server does not appear to be communicating with the DodoSim 206

FSX helicopter software.

This annunciator indicates a serious problem with communications between the

helicopter code and FSX and is not dependent upon panel power to illuminate.
