FUEL FLOW
Fuel flow is displayed on the ENGINE page by the FFLOW GPH
horizontal indicator. The indicator range is from
0 to 22 GPH with 2
GPH graduations, with a green arc from
0 to 15 GPH. A white
pointer indicates the measured fuel flow. A digital value for FFLOW
GPH is included on both the EIS LEAN and SYSTEM pages.
The fuel flow transducer is located in the engine fuel injection
system between the
fuellair control unit (servo) and the fuel
distribution manifold (flow divider). The transducer provides a digital
signal to the GEA-71 for display on the EIS. A red
X
through the
indicator means the indicating system is inoperative.
OIL PRESSURE
Engine oil pressure is shown on the ENGINE page by the OIL
PRES horizontal indicator. The indicator range is
0 to 120 PSI with
a red arc from
0 to 20 PSI, a green arc from 50 to 90 PSI (normal
operating range) and a red arc from 115 to 120 PSI. A white pointer
indicates actual oil pressure. Oil pressure is shown numerically on
the SYSTEM page.
When oil pressure is
0 to 20 PSI or 115 to 120 PSI, the pointer,
digital value, and label (OIL PRES) will change to red to show that
oil pressure is outside normal limits. If oil pressure exceeds either
the upper or lower limit while on the LEAN or SYSTEM page, the
EIS will return to the ENGINE page.
