Leaning to Last Peak (ENG Page - Full-Screen MFD)
If a fuel flow sensor is configured, the fuel flow value detected as the first cylinder
peaks is saved (see above). The fuel flow corresponding to peak EGT is drawn on the
fuel flow gauge as a hollow blue pointer. This can be used to determine if you are on
the rich side of peak (ROP) or the lean side of peak (LOP). Rich of Peak (ROP) if the fuel
flow pointer is above the blue triangle, or Lean of Peak (LOP) if the fuel flow pointer is
below the blue triangle.
The EIS Display (See Section 3.1) and the split-screen ENG Page will display the
cylinder whose temperature is currently closest to its own peak value (when Lean Assist
Mode is active) as a white pointer with the cylinder number. The peak temperature is
depicted by a hollow blue pointer, and the temperature deviation from peak (DEGT or
DTIT) is displayed in place of the normal temperature number in light blue text.
