CLUTCH

Back 1

This light warns the pilot whenever the electro-mechanical rotor belt tensioning system is running This system is activated automatically to maintain proper tension on the drive belts

Front 2

MR TEMP

Back 2

This light is activated if the termocouple mounted above the input drive bearing of the main rotor transmission detects that the bearing is running hot

Front 3

MR CHIP

Back 3

This light is activated if the magnetic plug on the bottom of the main rotor transmission has collected metal fragments There are two electrodes seperated by a small gap if metal particles in the oil collect across the gap the circuit is completed and the light is lit

STARTER ON

Back 4

This alerts the pilot to a hung starter

Front 5

TAIL ROTOR CHIP

Back 5

The tail rotor gear box has a chip detector similar to the one on the main rotor transmission

Front 6

LOW FUEL

Back 6

This light comes on when there is only 1 gallon of gas left in the helicopter Proper flight planning by the pilot normally precludes the fuel level ever getting this low

Front 7

LOW RPM

Back 7

This light comes on if main rotor RPM is below 95% An audible horn also activates at the same time If the collective is full down a microswitch defeats this system so that it isn't constantly activated during startup and shutdown

Dual Tachometer-The left hand needle indicates Engine RPM (revolutions per minute), the right hand needle indicates Main Rotor RPM.

Front 11

The rotor system can be operated between

Back 13

Altimeter-This instrument senses barometric pressure and indicates height above sea level based on that pressure.

Front 14

The Altimeter short indicator indicates

Whats this

Back 17

Manifold Pressure-By calculating this maximum and not exceeding it, the pilot derates the engine from the 160 horsepower which is actually available, to the derated maximum which is 124 horsepower continuous, or 131 horsepower for up to 5 minutes.
