EFIS-D100 Electronic Flight Information System - Dynon Avionics

OAT (Outside Air Temperature)
EFIS Operation
The EFIS-D100 supports the connection of an OAT to its EDC-D10A. If no OAT is connected to
the EFIS-D100, or to any other device in a DSAB system, you may manually set the outside
temperature.
The OAT info item displays 3 lines of text, containing outside air temperature, density altitude,
and true airspeed. To use the TAS/DA calculator without an OAT installed, manually enter the outside air temperature in
the EFIS > OATSET menu. When a temperature is manually input via the OATSET menu, a box is displayed around the
temperature in the info item, as shown in the image above.
When multiple units are connected to a DSAB network, one primary OAT is shared between all units. This can
be an OAT connected to an EFIS or an EMS. If the EFIS-D100 is displaying an OAT provided by another unit
in the system, changing the OAT type or install status on the EFIS-D100 has no effect on the displayed OAT.
This change is only used if the primary OAT (or entire DSAB network) fails and the EFIS switches to the
locally connected OAT.
ENGINE (Manifold Pressure and RPM)
The engine informational item allows you to display engine manifold pressure and RPM on the
EFIS page. This requires that the manifold pressure sensor and tachometer pickoff are properly
installed and configured on a DSAB-connected EMS-based product.
DIM – Changing screen brightness
In the EFIS > DIM menu, press BRITR or DRKR to change the brightness of the display. It is not possible to turn the
screen completely black. Note that if power to the EFIS-D100 is cycled, the screen is reset to full brightness.
The DIM function also exists in the EMS main page menu. You may dim the display via either menu.
