EFIS Operation
VSI (Rate of Climb)
The vertical speed indicator (VSI) consists of a single line with your current rate of climb or
descent. If you are currently gaining altitude, an up arrow is displayed to the right of the vertical
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
FlightDEK-D180 firmware version 3.0 and higher, VSI can be displayed as a graphical indicator next to the altitude tape.
OAT (Outside Air Temperature)
The FlightDEK-D180 supports the connection of an OAT to its EDC-D10A and/or an OAT
connected directly to the EMS connector. If neither type of OAT is connected to the FlightDEK-
D180, 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 FlightDEK-D180 is displaying an OAT provided by another
unit in the system, changing the OAT type or install status on the FlightDEK-D180 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.
