ENGINE INDICATION SYSTEM
1
Engine Manifold Pressure
Gauge (MAN IN)
DA40 only
Displays engine power in inches of Mercury (in Hg)
2
Tachometer (RPM)
Shows propeller speed in revolutions per minute (rpm); the red band
indicates propeller overspeed
3
Fuel Flow (FFLOW GPH)
Displays current fuel flow in gallons per hour (gph)
4
Exhaust Gas Temperature
Bar Graph (EGT °F)
Exhaust Gas Temperature (EGT) for each cylinder is represented as a bar;
below the graph, the EGT readout is given for the selected cylinder
(shown in light blue)
A hollow block appears to represent the peak EGT for the selected
cylinder when the ASSIST Softkey is pressed
5
EGT Deviation from Peak
(∆ PEAK)
Displays the current EGT deviation from peak for the selected cylinder
in degrees Fahrenheit (°F) when the
ASSIST Softkey is pressed
6
Cylinder Head Temperature
Bar Graph (CHT °F)
Head temperature for each cylinder is represented as a bar; below the
graph, the CHT readout is given for the selected cylinder (shown in
light blue)
The CYL SLCT and ASSIST softkeys become available after pressing the LEAN Softkey. The CYL SLCT
Softkey can be utilized to cycle through the cylinders and obtain information about a particular cylinder, shown
in light blue on the bar graphs. This softkey is disabled when the ASSIST Softkey is pressed or when a cylinder
experiences a caution or warning condition; the softkey remains disabled until the temperature returns to
normal.
The ASSIST Softkey can be utilized to assist in the leaning process. 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 light
blue, appears directly beneath the bar graph. When the ASSIST Softkey is pressed, the system automatically
switches to the first peak obtained and displays the temperature deviation from peak in degrees Fahrenheit below
the EGT readout.
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.
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 light blue.
Selecting the Engine Leaning Assist function:
From the Lean Display, press the ASSIST Softkey to identify the peak. The peak temperature for the selected
cylinder is indicated with a hollow block on the EGT Bar Graph and the temperature deviation from peak is
shown underneath the EGT Bar Graph.
