FUEL FLOW (Continued)
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 fuel/air control unit (servo) and the fuel distribution
manifold (flow divider). The transducer provides a signal to the engine
display that is processed and shown as fuel flow (FFLOW) on the EIS
pages. 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 band
from 0 to 20 PSI, a green band from 50 to 90 PSI (normal operating
range) and a red band 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.
When the engine speed (RPM) is in the green arc and the oil
temperature is in the green band, the oil pressure should be in the
green band. If oil pressure is below the green band or above the green
band, adjust the engine speed to maintain adequate oil pressure. When
engine speed is at idle or near idle, the oil pressure indication must be
above the lower red band. With the engine at normal operating oil
temperature, and engine speed at or close to idle, oil pressure below
the green band, but above the lower red band, is acceptable.
