The ASSIST Softkey aids in the leaning process by identifyingthepeakofthefirstcylinderwhosetemperature falls. If the temperature of the peaked cylinder exceeds the peak value, the peak value is not updated. Press the ASSIST Softkey to stop peak monitoring.

Normally-aspirated Aircraft

For normally-aspirated aircraft, when a cylinder peaks, its peak is represented by a hollow block on the EGT Bar Graph. The EGT readout for the peaked cylinder, indicated on the bar graph in light blue, appears directly beneath the bar graph. The system automatically switches to the first peak obtained and displays the temperature deviation from peak (∆PEAK) in degrees Fahrenheit (°F) below the EGT readout.

Turbocharged Aircraft

Leaning for turbocharged aircraft is done with reference to the Turbine Inlet Temperature (TIT). When the temperature peaks, the numeric readout (∆PEAK) appears below the TIT Indicator and displays the difference between peak and current TITs, in degrees Fahrenheit (°F). If a peak is not displayed, underscores are shown until one is established.

3.3SYSTEM DISPLAY

NOTE: Fuel calculations do not use the aircraft fuel quantity indicators and are calculated from the last time the fuel was reset.

NOTE: The pilot should refer to the Pilot’s Operating Handbook (POH) for fuel values and limitations. The displayed fuel remaining can be adjusted up to 53 gal (Models 172R,172S) or 87 gal (Models 182T,T182T, 206H,T206H).

SECTION 3 – ENGINE

INDICATION SYSTEM (EIS)

The System Display is accessed by pressing the ENGINE Softkey followed by the SYSTEM Softkey and shows critical engine, fuel, and electrical parameters.

Fuel calculations are based on the fuel flow totalizer and the displayed fuel remaining, adjusted by the pilot using the following softkeys:

•RST FUEL – Resets totalizer-based fuel remaining (GAL REM) to zero and the fuel used (GAL USED) to zero

•GAL REM – Gives access to softkeys for adjusting the amount of fuel remaining for purposes of fuel calculations

Fuel remaining can be adjusted in one or ten-gallon increments using the appropriate softkeys. Softkeys also allow entering the full tank quantity for the aircraft or the tab quantity, which is 35 gallons (Models 172R and 172S) or 64 gallons (Models 182T, T182T, 206H, and T206H).

SECTION 3 – ENGINE

INDICATION SYSTEM (EIS)

1Engine Manifold Pressure Gauge (MAN IN)

Models 182, T182, 206, T206 – Displays engine powerininchesofmercury(inHg). 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).

2Tachometer (RPM) – Shows propeller speeds in revolutions per minute (rpm). Red range indicates propeller overspeed warning; a white high-rpmrangeindicatesabovenormaloperating speeds (Models 172S, 206 and T206).

3Oil Pressure (OIL PSI) – Displays pressure of the oil supplied to the engine in pounds per square inch (psi).

4OilTemperature(OIL°F)–Displaystheengine oil temperature in degrees Fahrenheit (°F).

5Engine Hours (Tach) (ENG HRS) Models 182, T182, 206, T206 – A numeric readout gives the time (in hours) the engine has been in service.

6Vacuum Pressure Indicator (VAC) Models182, T182, 206, T206 – Displays vacuum pressure.

7Fuel Flow (FFLOW GPH) – Shows the current fuel flow in gallons per hour (gph).

8Calculated Fuel Used (GAL USED) – Shows quantity of fuel used in gallons based on fuel flow since last reset.

9Set Fuel Remaining (GAL REM) – Shows current fuel remaining in gallons as set by the pilot and adjusted for fuel burn since last set.

10Fuel 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–Landright–R). When full, the indicator displays to 35 gallons per side (26 gallons for the

Models 172R and 172S).

11Voltmeter (M, E BUS VOLTS) – Displays the main and essential bus voltages.

12Ammeter (M, S BATT AMPS) – Shows the main and standby battery load in amperes.
