3.3 LEANING ASSIST MODE
NOTE
:
The pilot should follow the engine manufacturer’s recommended leaning procedures in the Pilot’s
Operating Handbook (POH).
A leaning assist function is available on the Engine Page to assist in the leaning process.
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.
