SECTION 3: ENGINE INDICATION
SYSTEM (EIS)
NOTE: Refer to the Pilot’s Operating Handbook
(POH) for limitations.
EIS information is presented in three displays, accessed
using the ENGINE Softkey on the MFD:
• Engine Display – Default display, shows all critical
engine, fuel, and electrical indicators
• Lean Display – Provides engine leaning
information
• System Display – Shows numeric readouts of
critical engine, fuel, and electrical indicators
Green and white bands indicate normal ranges of
operation; yellow and red bands indicate caution and
warning, respectively. If sensory data to an instrument
becomes invalid or unavailable, a red “X” is shown across
the instrument.
3.1 ENGINE DISPLAY
The Engine Display is the default EIS display and can
be displayed after viewing other EIS displays by pressing
the ENGINE Softkey.
The EIS automatically defaults back to the Engine
Display from the Lean or System Display when certain
parameters are exceeded. Fluctuations in engine speed
and fuel quantity above certain levels, depending on the
airframe, also cause reversion back to the Engine Display.
1
Engine Manifold Pressure Gauge (MAN IN)
Models 182T, T182T, 206H, T206H – Displays
engine power in inches of mercury (in Hg).
Turbocharged aircraft have a red portion of the
gauge indicating the maximum manifold pressure
range. A white tick mark is displayed indicating
the cruise manifold pressure (Model T182T only).
2
Tachometer (RPM) – Shows propeller speeds
in revolutions per minute (rpm). Red range
indicates propeller overspeed warning; a white
high-rpm range indicates above normal operating
speeds (Models 172S, 206H, and T206H)
3
Fuel Flow Indicator (FFLOW GPH) – Shows
the current fuel flow in gallons per hour (gph).
For turbocharged aircraft, the indicator displays
a small stand-alone green band indicating
maximum takeoff fuel flow. A white tick mark
indicates the maximum cruise fuel flow (Model
T182T only).
4
Oil Pressure Indicator (OIL PRES) – Displays
pressure of the oil supplied to the engine in
pounds per square inch (psi).
5
Oil Temperature Indicator (OIL TEMP)
– Displays the engine oil temperature in degrees
Fahrenheit (°F).
6
Cylinder Head Temperature Indicator (CHT)
Models 182T, T182T, 206H, T206H – Shows
the head temperature of the hottest cylinder
(number shown in triangular pointer) in degrees
Fahrenheit (°F).
7
Exhaust Gas Temperature Indicator (EGT)
Normally-aspirated Aircraft – Displays the
exhaust gas temperature of the hottest cylinder
(number shown in triangular pointer) in degrees
Fahrenheit (°F).
8
Turbine Inlet Temperature Indicator (TIT)
Turbocharged Aircraft – Displays the temperature
at the turbine inlet in degrees Fahrenheit (°F).
9
Vacuum Pressure Indicator (VAC) Models
172R and 172S – Displays vacuum pressure.
