Leaning Assist Mode
NOTE: The pilot should follow the engine manufacturer’s recommended
leaning procedures in the Pilot’s Operating Handbook (POH).
Accessing Leaning Assist Mode:
1)
Press the ENGINE Softkey to display the Engine Page.
2)
Press the ASSIST Softkey to identify peaks.
When the ASSIST Softkey is pressed, the system initially highlights the number
and places a light blue box around the EGT readout of the cylinder with the hottest
EGT. The ∆ Peak temperature is the difference between the peak temperature and the
present temperature for the peaked cylinder. When the first peak is detected, “1st” is
annunciated below that cylinder’s EGT bar and the temperature is enclosed in a light
blue box.
The system continues to detect peak EGTs for each cylinder lean of peak as the
fuel flow is decreased, and the peak of each cylinder’s EGT is indicated by a light blue
marker on the graph. Once all cylinders are lean of peak, the last cylinder to peak is
denoted by the “Last” annunciation below its bar on the graph.
