3.3.4.4 Transmission Instruments

14. Transmission Oil Temperature & Pressure - This dual gauge displays both the

temperature and pressure of the transmission oil. If the transmission has sustained

damage due to misuse, (i.e. repeated or sustained over-torquing), then these gauges

could be your first indication that it may be on the way to failing.

3.3.4.5 Fuel System Instruments

15. Fuel Level - This gauge displays the aircraft’s fuel level. Note that the tank can hold 91

US Gallons of fuel, though the gauge only displays up to 75.

Pilot Information:

If both fuel pumps are off then usable fuel in the tank is 10 Gallons. If

one is off then usable fuel is 5 Gallons. The turbine will cease combustion if fuel drops

below these levels in either of these conditions.

16. Fuel Pressure meter - This gauge displays the current fuel pressure in PSI. It is effected

by atmospheric pressure. Above 6000’ MSL the aircraft requires the use of the fuel pumps

to provide enough fuel pressure to start and maintain combustion. The fuel pressure can

be observed to drop slightly as fuel is introduced to the engine during the start procedure.

3.3.4.6 Electrical System Instruments

17. Electrical Load meter - This gauge displays the drain on the electrical system represented

as a proportion of the total potential output of the generator.

18. Volt Meter - The cockpit clock has many features and is also used in navigation timings,

but it also doubles as a Voltmeter. A push button switches the unit from time display to bus

voltage display. If the starter motor fails to drive the compressor properly, then this display

may indicate a low battery voltage as the reason.

19. Annunciator Lights - These lights alert the pilot to any caution or warning of which he

should be aware. Yellow lights signify a caution, whilst red lights signify a serious

condition which should be rectified or acted upon immediately, where failure to do so may

damage aircraft components.

Pilot Information: The

annunciator electrical system, including the engine out and rotor

RPM low warning sounds, are isolated by the CAUTION LT circuit breaker on the overhead

panel.

I. GEN FAIL - the generator is not generating electricity, indicating that either the

engine is not running and/or the Generator Field CB or Generator Switch are out

or off respectively. Whilst this condition remains, the battery voltage is being

drained.

II. AF FUEL FILTER - The fuel filter has become clogged and bypassed. This occurs

over time as fuel flows to the engine and is accentuated by running the tank low.

Servicing the helicopter, (in “Cumulative Wear” mode), remedies the condition.

Exhaust gas temperature will read slightly higher when the filter is bypassed due

to impurity of the fuel.

III. BAGGAGE DOOR - This light illuminates when the aircraft’s baggage door is open.
