ENGINE INDICATION SYSTEM
LEAN PAGE
The Lean Page is accessed by pressing the LEAN soft-
key. A digital readout for fuel flow resides below the ta-
chometer. Beneath the fuel flow indication are bar graphs
and numeric readouts for exhaust gas temperature (EGT),
temperature deviation from peak and cylinder head tem-
perature (CHT) in degrees Fahrenheit. 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 (caution) or red
(warning)
• 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):
From the Lean Page, press the
CYL SLCT
softkey
to cycle through each cylinder and view the EGT
and CHT.
NOTE: The pilot should follow the engine
manufacturer’s recommended leaning procedures
in the Aircraft Flight Manual Supplement
(AFMS).
Assist
The
ASSIST
softkey can be utilized to assist in the
leaning process. When a cylinder peaks, its peak is repre-
sented 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 sys-
tem automatically switches to the first peak obtained and
displays the temperature deviation from peak in degrees
Fahrenheit below the EGT readout.
The ASSIST softkey is available by pressing the LEAN
softkey.
To select the Assist function:
From the Lean Page, press the
ASSIST
softkey
to identify the peak.
