ENGINE INDICATION SYSTEM
6.3 LEAN PAGE
The Lean Page is accessible by pressing the LEAN
softkey. Beneath the tachometer are bar graphs and nu
-
meric readouts for exhaust gas temperature (EGT), tem-
perature from peak and cylinder head temperature (CHT)
in degrees Fahrenheit (Refer to Figure 6-2 on the follow-
ing page). By default, the numeric readouts of the EGT
and CHT are associated with the hottest cylinder and are
graphically indicated in cyan (light blue). Color coding
for the EGT and CHT bar graphs is listed below:
• Cyan (light blue) – Selected Cylinder (EGT and
CHT)
• White – Normal (EGT and CHT)
• Yellow – Caution (CHT only)
• Red – Warning (CHT only)
CYLINDER SELECT
The CYL SLCT softkey can be utilized to obtain in-
formation about a particular cylinder. The CYL SLCT
softkey becomes disabled when:
• a particular cylinder turns yellow or red until the
temperature decreases and returns to normal,
which is indicated by white on the bar graph
• the ASSIST softkey is pressed
The CYL SLCT softkey is available by pressing the
LEAN softkey.
To monitor the desired cylinder(s):
1. From the Lean Page, press the
CYL SLCT softkey
to cycle through each cylinder and view the EGT
and CHT.
ASSIST
The ASSIST softkey can be utilized to assist in the
leaning process. When a cylinder EGT peaks, its peak is
represented by a hollow bar on the EGT bar graph. The
EGT readout for the peaked cylinder, indicated in cyan
(light blue), appears directly beneath the bar graph. The
system automatically switches to the first peak obtained
and displays the temperature deviation from peak in de-
grees Fahrenheit below the EGT readout.
NOTE: The pilot should follow the engine man-
ufacturer’s recommended leaning procedures in
the Pilot’s Operating Handbook (POH).
The ASSIST softkey is available by pressing the LEAN
softkey.
To select the Assist function:
1. From the Lean Page, press the
ASSIST softkey
to identify the peak.
