Engine Indication System
Depending on the configuration, Lean Assist will monitor either the Exhaust Gas
Temperatures (EGT) or the Turbine Inlet Temperatures (TIT), and provide Lean Assist
indications accordingly.
Once the temperature rises, peaks, or decreases, as configured by the system, peak
temperature is determined, and the following will occur:
• The peak temperature will be indicated above the corresponding cylinder bar with a cyan
line for EGT, or gray line for TIT.
• If enough space is available on the display, the peak temperature will be displayed above
the line.
• The difference between the cylinder's current temperature and the peak temperature is
displayed above the current temperature for the first, in black text on a cyan background,
and last cylinder, in cyan text with a cyan box around it, to peak.
Once a peak occurs, the Fuel Flow gauge below the graph will display a magenta triangle
indicating the fuel flow when the first or last cylinder peaked. The difference in the current fuel
flow and the peak fuel flow will be shown to the right of the gauge.
