AIRPLANE AND SYSTEMS DESCRIPTION
ENGINE
(Continued)
OIL PRESSURE (Continued)
When the engine speed
(RPM) is in the green arc and the oil
temperature is in the green arc, the oil pressure should be in the
green arc.
If
oil pressure is below the green arc or above the green
arc, 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 arc. With the engine at normal
operating oil temperature, and engine speed at or close to idle, oil
pressure below the green arc (but above the lower red arc) is
acceptable.
In cold weather, the oil pressure will initially be high (close to the
upper red arc when the engine is started). As the engine and oil
warm up, the oil pressure will come down into the green arc.
The oil pressure transducer, connected to the engine forward oil
pressure port, provides
a
signal to the GEA-71 that is processed
and shown as oil temperature on the EIS. A separate low oil
pressure switch causes an "OIL PRESSURE" annunciation on the
PFD when oil pressure is
0 to 20 PSI. A red
X
through the oil
pressure indicator means that the indicating system is inoperative.
