speed value. If you are losing altitude, a down arrow is displayed to the right of the vertical speed value. The units of VSI
are feet/minute. Note that in the MODERN display (EFIS > SETUP > STYLE), found in EFIS-D10A firmware version
3.0 and higher, VSI can be displayed as a graphical indicator next to the altitude tape.
OAT (Outside Air Temperature)
The EFIS-D10A supports the connection of an OAT to the EFIS connector and/or an OAT
connected to the EMS connector. If neither type of OAT is connected to the EFIS-D10A, 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-D10A is displaying an OAT provided by another unit
in the system, changing the OAT type or install status on the EFIS-D10A has no effect on the displayed OAT.
This change is only be 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.
