3. DESCRIPTION
A. Gages
The gages, two on each wing, are the float type and are attached to the rear of the tanks.
B. Tank indicators
The tank indicators are fitted into engine monitoring cluster and display the remaining fuel quantities.
C. Fuel pressure switch
The fuel pressure switch allows to transmit the correct operation of the electric fuel pump to the pilot.
It controls the illumination of the pump indicator light on the advisory panel when the pressure supplied by electric fuel pump is :
- "JAEGER" pressure switch P a 11.6 ± 0.8 PSI (0.8 ± 0.05 bar)
- "HOBBS" pressure switch P z 10 ± 2 PSI (0.7 ± 0.14 bar)
It is located at the engine pump intake.
D. Microswitch of selector valve indicator light
The microswitch of selector valve indicator light allows to transmit the open or closed position of the selector valve to the pilot.
It controls the extinguishing of the selector valve indicator light on the advisory panel when it is on the L.H. or R.H. position.
It is located on the selector valve control.
E. Low level detector
The low level detector (one for each tank) transmits to the pilot the minimum quantity of usable fuel that remains in any of the two tanks.
It is located on the root pressure bulkhead of each tank. Option Pre-MOD. 171
It controls the illumination of a red indicator light on the advisory panel when the usable fuel quantity that remains in any of the two tanks is approximately 6.6 US Gal (25 liters).
