3.3 ENGINE LEANING
While viewing the EIS-ENGINE Page, press the LEAN
Softkey.
As the mixture is leaned, one of the cylinder’s exhaust
temperature will peak. This is indicated by ‘1st’ being
displayed below the first cylinder to peak. See Figure 3-
4. The ∆ Peak temperature is the difference between the
peak temperature and the present temperature.
Continuing to lean the mixture will cause each cylinder
to peak until the last of the cylinders peaks. This is
indicated by ‘Last’ being displayed below the last peaking
cylinder as shown in Figure 3-5.
Pressing the ENGINE Softkey returns the MFD to de-
fault operation.
