3.3 LEANING ASSIST MODE
NOTE :
The pilot should follow the engine manufacturer’s recommended leaning procedures in the Aircraft
Flight Manual Supplement (AFMS).
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 open the Engine Page.
2) Press the
LEAN
Softkey to identify peaks.
3)
Press the LEAN Softkey again to exit Leaning Assist Mode.
When the LEAN Softkey is pressed, the system initially highlights the number and 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 marked in light blue on the graph.
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.
