Garmin G1000 Pilot’s Guide for the Diamond DA40/40F 190-00592-06 Rev. A86ENGINE INDICATION SYSTEMSYSTEMOVERVIEWFLIGHTINSTRUMENTSEISAUDIO PANEL& CNSFLIGHTMANAGEMENTHAZARDAVOIDANCEAFCSADDITIONALFEATURESAPPENDICESINDEXLEAN DISPLAYNOTE: The pilot should follow the engine manufacturer’s recommended leaning procedures in the AircraftFlight Manual Supplement (AFMS).The EIS Lean Display provides information and a user interface to perform engine leaning. Exhaust gas(EGT) and head (CHT) temperatures for each cylinder are displayed in bar graph form with a readout for thetemperature of the selected cylinder shown below each graph.Accessing the EIS Lean Display:1) Press the ENGINE Softkey.2) Press the LEAN Softkey.3) To return to the default Engine Display, press the ENGINE or BACK Softkey.By default, the cylinder with the hottest temperature is selected (number highlighted in light blue) when theLEAN Softkey is pressed. Bars for cylinders with temperatures in the normal range are shown in white. On theCHT Bar Graph, caution and warning conditions are indicated in yellow and red, respectively.Since only one cylinder’s EGT and CHT are displayed at a time, this information can be cycled through foreach cylinder using the CYL SLCT Softkey; the selected cylinder’s number is highlighted in light blue on thebar graphs. This softkey is disabled when Leaning Assist Mode is selected.Monitoring the desired cylinder’s temperatures:From the Lean Display, press the CYL SLCT Softkey to cycle through each cylinder and view its temperatureinformation. The selected cylinder number is highlighted in light blue.While in Reversionary Mode, the leaning assist function is available when the ASSIST Softkey is pressedfrom the Lean Display to assist in the leaning process (refer to the section on Leaning Assist Mode for moreinformation).1 Engine Manifold PressureGauge (MAN IN HG)Displays manifold pressure in inches of Mercury (in Hg) to indicate enginepower (DA40 only)2 Tachometer (RPM) Displays propeller speed in revolutions per minute (rpm); the red bandindicates propeller overspeed3 Fuel Flow (FFLOW GPH) Displays current fuel flow in gallons per hour (gph)4 Exhaust Gas TemperatureBar Graph (EGT °F)Exhaust Gas Temperature (EGT) for each cylinder is represented as a bar;below the graph, the EGT readout is given for the selected cylinder(shown in light blue)A hollow block appears to represent the peak EGT for the selected cylinderwhen the ASSIST Softkey is pressed5 EGT Deviation from Peak(∆ PEAK)Displays the current EGT deviation from peak for the selected cylinder indegrees Fahrenheit (°F) when the ASSIST Softkey is pressed6 Cylinder Head TemperatureBar Graph (CHT °F)Head temperature for each cylinder is represented as a bar; below thegraph, the CHT readout is given for the selected cylinder (shown inlight blue)
