c. Miscellaneous Instruments.
Miscellaneous instruments (fig. 8–3) consist of the pilot fuel quantity
indicator, refuel panel FUEL QTY indicator, FSC, pilot emergency hydraulic pressure indicator, pilot dual hydraulic
pressure indicator, clock, and the pilot outside air temperature (OAT) indicator.
(1) Pilot FUEL Quantity Indicator.
The pilot FUEL quantity indicator, located in the pilot instrument
panel, has two vertical scale displays that are positioned side–by–side. A TOTAL digital readout is mounted below
the vertical scale displays. Forward fuel cell fuel quantity is displayed on the left scale and the aft fuel cell fuel
quantity is displayed on the right scale. Total available fuel is displayed on the TOTAL digital readout.
(2) Refuel Panel FUEL QTY Indicator.
The FUEL QTY indicator, located on the refuel panel on the
forward right side of the fuselage (access door R160), has two scales and two movable pointers. The right FUEL
QTY scale measures fuel level in the FWD fuel cell. The left FUEL QTY scale measures fuel level in the AFT fuel
cell. The pointers move between empty (E) and full (F) markers as fuel levels change.
(3) FSC.
The FSC, located on the left side of the helicopter nose (access door L40), converts forward
and aft fuel cell sensor inputs into 0 to 5 VDC outputs for the FUEL quantity indicator and the refuel panel FUEL
QTY indicator.
(4) Pilot Emergency Hydraulic Pressure Indicator.
The pilot emergency hydraulic pressure indicator,
located in the pilot instrument panel, displays emergency hydraulic pressure from 0 to 5000 psi.
(5) Pilot Dual Hydraulic Pressure Indicator.
The pilot dual hydraulic pressure indicator, located in the
pilot instrument panel, displays primary and utility pressure from 0 to 6000 psi.
(6) Clocks.
The clocks, located in the pilot and CPG instrument panels, display time of day in hours,
minutes, and seconds. The clocks also show elapsed time in minutes.
(7) Pilot OAT Indicator.
The pilot OAT indicator, located in the left side of the pilot station fuselage, has
a shielded sensing element which extends through the fuselage to the outside air. The luminous dial shows
temperature from –70 C to 50 C.
