ENGINE INDICATION SYSTEM
7.2 LEAN
The Lean Page is accessible by pressing the LEAN soft-
key. A color-coded horizontal bar indicator for fuel quan-
tity and a numeric readout for fuel flow reside below the
tachometer. Beneath the fuel flow indication is the turbo
inlet temperature indicator (turbocharged) followed by
bar graphs and numeric readouts for exhaust gas tempera-
ture (normally aspirated) and cylinder head temperature
in degrees Fahrenheit. By default, the numeric readouts
of 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:

coding for the EGT and CHT bar graphs is listed below:
• Cyan – Selected cylinder (EGT and CHT)
• White – Normal (EGT and CHT)
• Yellow – Caution (CHT only)
• Red – Warning (CHT only)
• White – Normal (EGT and CHT)
• Yellow – Caution (CHT only)
• Red – Warning (CHT only)
The temperature deviation from peak in degrees Fahr-
enheit for normally aspirated aircraft is displayed beneath
the EGT readout.

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), until the temperature
decreases and returns to normal, which is indicated by
white on the bar graph. It is also disabled when 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.
Lean Assist
The ASSIST softkey can be utilized to assist in the
leaning process.
Normally Aspirated

When a cylinder 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 tem-
perature deviation from peak in degrees Fahrenheit below
the EGT readout.

NOTE: The pilot should follow the engine man-
ufacturer’s recommended leaning procedures in
the Aircraft Flight Manual (AFM).
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.
NOTE: The Lean Assist function is not available
for the turbocharged Mooney models.
NOTE: If any parameters are exceeded the system
automatically switches back to the default
