ENGINE INDICATION SYSTEM

NORMALLY-ASPIRATED

When the 

ASSIST

 Softkey is selected, the system initially highlights the number and EGT readout of the 

cylinder with the hottest EGT.  For the O-540-series, O-360-series, and O-320-series engines, the Carburetor 

Temperature Indicator is removed from the display.

When the first peak is detected, the cylinder numbers disappear, “1st” is annunciated in light blue below that 

cylinder’s EGT bar, the temperature is marked in light blue on the graph, and the EGT readout is outlined.

(First Cylinder)

The system continues to detect peak EGTs for each cylinder as the fuel flow is decreased and the peak of 

each cylinder’s EGT is indicated by a light blue marker.  The last cylinder to peak is denoted by the “Last” 

annunciation below its bar on the graph and the EGT readout is outlined in light blue.
