Oil Temperature
Oil temperature is shown in the upper right corner of the ENGINE
page, opposite the oil pressure scale, as both a simulated temperature
gage and as a digital value. The gage pointer sweeps a scale range
from 75°F to 250°F in 50°F increments. The digital temperature value
is displayed in white numerals below the gage.
The oil temperature sensor is mounted below the oil cooler and
provides a signal to the Engine Airframe Unit that is processed and
transmitted to the Engine Indicating System for display.
Oil Pressure
Oil Pressure is shown in the upper right corner of the ENGINE page,
opposite the oil temperature scale, as both a simulated pressure gage
and as a digital value. The gage pointer sweeps a scale range from 0
to 90 PSI in 10 PSI increments. The digital pressure value is displayed
in white numerals below the gage.
The oil pressure sensor is mounted below the oil cooler and provides a
signal to the Engine Airframe Unit that is processed and transmitted to
the Engine Indicating System for display.
Manifold Pressure Gage
Manifold pressure is shown in the upper center portion of the ENGINE
page as both a simulated pressure gage and as a digital value. The
gage pointer sweeps a scale range from 10 to 35 inches Hg in 1 inch
Hg increments. The digital MAP value is displayed in white numerals
below the gage. The manifold pressure sensor is mounted in the
induction air manifold near the throttle body and provides a signal to
the Engine Airframe Unit that is processed and transmitted to the
Engine Indicating System for display.
Percent Power Gage
Percent power is shown in the upper left corner of the ENGINE page
as both a simulated gage and as a digital value. The percent power
gage sweeps a scale marked from 0 to 100 percent in 5 percent
increments. The digital percent power value is displayed in white
numerals below the gage. The display units calculate the percentage
of maximum engine power produced by the engine based on an
algorithm employing manifold pressure, indicated air speed, outside
air temperature, pressure altitude, engine speed, and fuel flow.
