ENGINE INDICATION SYSTEM
LEAN DISPLAY
NOTE:
Follow the engine manufacturer’s recommended leaning procedures in the AFM.
NOTE:
Turbocharged Piper models are not equipped with the Lean Assist function.
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. By default, the cylinder with the hottest
temperature is selected (number highlighted in light blue) when the
LEAN
Softkey is pressed. Turbine inlet
temperature (TIT) is shown in place of EGT for turbocharged aircraft.
Bars for cylinders with temperatures in the normal range are shown in white. On the CHT Bar Graph, a
warning condition for a cylinder is indicated in red.
Accessing the EIS Lean Display:
1)
Press the
ENGINE
Softkey.
2)
Press the
LEAN
Softkey.
3)
To return to the default Engine Display, press the
ENGINE
or
BACK
Softkey.
The
CYL SLCT
Softkey becomes available after pressing the
LEAN
Softkey. The
CYL SLCT
Softkey can be
utilized to cycle through the cylinders and obtain information about a cylinder, highlighted in light blue on the
bar graph(s). This softkey is disabled when the
ASSIST
Softkey is pressed or when a cylinder experiences a
warning (red) condition; this softkey remains disabled until the temperature returns to normal.
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.
An Engine Leaning Assist Function is available to assist in the leaning process for normally-aspirated aircraft.
When the
ASSIST
Softkey is pressed, the system automatically switches to the first peak obtained and displays
the temperature deviation from peak (
∆
PEAK) in degrees Fahrenheit below the EGT readout for the peaked
cylinder. When a cylinder peaks, its number is indicated in light blue and its peak is represented by a light
blue bar on the EGT bar graph. Lean Assist continues to monitor this cylinder unless the temperature for the
cylinder exceeds peak. If peak is exceeded, Lean Assist is reset.
Selecting the Engine Leaning Assist Function (normally-aspirated aircraft):
From the Lean Display, press the
ASSIST
Softkey to identify the peak. The EGT for the selected cylinder (number
highlighted in light blue) and its deviation from peak temperature are displayed beneath the EGT Bar Graph.
