ENGINE INDICATION SYSTEM
LEAN ENGINE PAGE
Accessing the EIS Lean Display:
1) On the MFD, press the Engine Softkey.
2) Press the Lean softkey.
From the Lean Page, the CYL SLCT and Assist Softkeys can be utilized to obtain information about specific
cylinders on both the EGT and CHT graphs. Pressing the CYL SLCT Softkey cycles through the cylinders; the
selected cylinder number is displayed in cyan. The CYL SLCT Softkey is disabled during warning or caution
conditions or when the Assist Softkey is pressed.
Monitoring the desired cylinder's EGT and CHT:
From the Lean Page, press the CYL SLCT Softkey to cycle through each cylinder and view its EGT and CHT. The
selected cylinder is shown in cyan.
When the Assist Softkey is selected, the system initially highlights and selects the cylinder number with
the hottest EGT and displays its temperature below the EGT bar graph. A readout showing the difference
between peak (DPEAK) and the current temperature for the selected cylinder is displayed the EGT numerical
temperature indication.
As the mixture is leaned, a cyan line will appear above each cylinder to indicate EGT peak. Refer to the POH
for the recommended mixture adjustment procedures.
Monitoring of the cylinder continues until the Assist Softkey is pressed again which disables lean assist and
removes the peak lines from the bar graph and the temperature deviation from peak (DPEAK). The system then
returns to seeking the hottest cylinder.
FUEL CALCULATIONS
Fuel calculations do not use the aircraft fuel quantity indicators and are calculated from the last time
NOTE:
the fuel was reset.
Fuel used (GAL Used) and range (in nautical miles) are calculated based on the displayed fuel remaining
(GAL REM) and the fuel flow totalizer. The calculated range also takes into account the aircraft' s heading and
the wind direction and speed.
