ENGINE INDICATION SYSTEM

SECTION 3 ENGINE INDICATION SYSTEM (EIS)

NOTE: Refer to the Pilot’s Operating Handbook (POH) for limitations.

The G1000 Engine Indication System (EIS) displays critical engine, electrical, fuel, and other system parameters on the left side of the Multi Function Display (MFD) during normal operations. In reversionary mode, the displays are re-configured to present Primary Flight Display (PFD) symbology together with the EIS (refer to the System Overview for information about Reversionary Mode).

EIS

Figure 3-1 Multi Function Display

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

The Tachometer and Engine Manifold Pressure Gauge (Models 182T, T182T, 206H, and T206H) are present at the top of all three displays. All displays also show fuel flow and quantity.

EIS instrument types include round dial gauges, horizontal bar indicators, bar graphs, and digital readouts. Green and white bands indicate normal ranges of operation; yellow and red bands indicate caution and warning, respectively. When unsafe operating conditions occur, readouts and labels change color corresponding to the level of the condition; warnings also flash. Readouts and pointers on the horizontal bar indicators appear in white to indicate normal operation and change to yellow or red to indicate caution or warning conditions. If sensory data to an instrument becomes invalid or unavailable, a red “X” is shown across the instrument.

ENGINE INDICATION SYSTEM

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. This display shows the dial gauge(s), horizontal bar indicators, and readouts for critical engine and electrical parameters.

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.
