Accessing the EIS Lean Display:
1)
On the MFD, press the
Engine
Softkey.
2)
Press the
Lean
softkey.
From the Lean display, 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 display, 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 showing the difference between peak
(
D
PEAK) 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
current version of the pertinent flight manual for the recommended mixture adjustment procedures.
Monitoring of the cylinder continues until the
Assist
Softkey is pressed again or if another page is selected,
which disables lean assist and removes the peak lines from the bar graph and the temperature deviation from
peak (
D
PEAK). The system then returns to seeking the hottest cylinder.
FUEL CALCULATIONS
NOTE:
Fuel calculations do not use the aircraft fuel quantity indicators and are calculated from the last time
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.
