SECTION 3 – ENGINE
INDICATION SYSTEM (EIS)
1 Engine Manifold Pressure Gauge (MAN IN)
Models 182, T182, 206, T206 – 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 T182 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, 206 and T206).
3 Oil Pressure (OIL PSI) – Displays pressure
of the oil supplied to the engine in pounds per
square inch (psi).
4 Oil Temperature (OIL °F) – Displays the engine
oil temperature in degrees Fahrenheit (°F).
5 Engine Hours (Tach) (ENG HRS) Models 182,
T182, 206, T206 – A numeric readout gives the
time (in hours) the engine has been in service.
6 Vacuum Pressure Indicator (VAC) Models 182,
T182, 206, T206 – Displays vacuum pressure.
7 Fuel Flow (FFLOW GPH) – Shows the current
fuel flow in gallons per hour (gph).
8 Calculated Fuel Used (GAL USED) – Shows
quantity of fuel used in gallons based on fuel flow
since last reset.
9 Set Fuel Remaining (GAL REM) – Shows
current fuel remaining in gallons as set by the
pilot and adjusted for fuel burn since last set.

10 Fuel Quantity Indicator (FUEL QTY GAL)
– Shows the quantity of fuel in the tanks, in
gallons, ranging from zero to full (F) for each fuel
tank (left–L and right–R). When full, the indicator
displays to 35 gallons per side (26 gallons for the
Models 172R and 172S).
11
Voltmeter (M, E BUS VOLTS) – Displays the
main and essential bus voltages.
12 Ammeter (M, S BATT AMPS) – Shows the
main and standby battery load in amperes.
