LEAN DISPLAY
NOTE: The pilot should follow the engine manufacturer’s recommended leaning procedures in the Aircraft
Flight Manual (AFM).
NOTE: The Lean Assist function is not available for the turbocharged M20M or M20TN.
The EIS Lean Display provides information and a user interface to perform engine leaning. Exhaust gas
(EGT) and head (CHT) temperatures for each cylinder are displayed in bar graph form with a readout for the
temperature of the selected cylinder shown below each graph.
Accessing the EIS Lean Display:
1) Press the ENGINE Softkey.
2) Press the LEAN Softkey.
3) To return to the default EIS Engine Strip, press the ENGINE or BACK Softkey.
By default, the cylinder with the hottest temperature is selected (number highlighted in light blue) when the
LEAN Softkey is pressed. Bars for cylinders with temperatures in the normal range are shown in white. On the
CHT Bar Graph, caution and warning conditions are indicated in yellow and red, respectively.
Since only one cylinder’s EGT and CHT are displayed at a time, this information can be cycled through for
each cylinder using the CYL SLCT Softkey; the selected cylinder’s number is highlighted in light blue on the
bar graphs. This softkey is disabled when Leaning Assist Mode is selected.
Monitoring the desired cylinder’s temperatures:
From the Lean Display, press the CYL SLCT Softkey to cycle through each cylinder and view its temperature
information. The selected cylinder number is highlighted in light blue.
While in Reversionary Mode, the leaning assist function is available when the ASSIST Softkey is pressed
from the Lean Display to assist in the leaning process (refer to the section on Leaning Assist Mode for more
information).
