LEAN ENGINE PAGE

Accessing the EIS Lean Display:
1) On the MFD, press the Engine Softkey.
2) Press the Engine softkey.
3) Press the Lean softkey.
From the Lean Page, the CYL SLCT and Assist Softkeys can be utilized to obtain
information about specific cylinders on both the EGT and CHT graphs. Pressing the
CYL SLCT Softkey cycles through the cylinders; the selected cylinder number is dis-
played in cyan. The CYL SLCT Softkey is disabled during warning or caution condi-
tions or when the ASSIST Softkey is pressed.
Monitoring the desired cylinder's EGT and CHT:
From the Lean Page, press the CYL SLCT Softkey to cycle through each
cylinder and view its EGT and CHT. The selected cylinder is shown in cyan.
When the ASSIST Softkey is selected, the system initially highlights and selects
the cylinder number with the hottest EGT and displays its temperature below the EGT
bar graph. A readout showing the difference between peak (DPEAK) and the current
temperature for the selected cylinder is displayed the EGT numerical temperature in-
dication.
As the mixture is leaned, a cyan line will appear above each cylinder to indicate
EGT peak. Refer to the POH and AFM for the recommended mixture adjustment
procedures.
