OATSET – Setting Temperature Offset
If you did not purchase an EFIS or EMS outside air temperature sensor from Dynon Avionics, you may still manually
adjust the OAT to an approximate value. With this manually entered information, the EFIS-D10A calculates and displays
true airspeed (TAS) and density altitude as it does when an OAT is connected. Ensure that you have indicated that an
EFIS OAT is not installed; enter the EFIS > SETUP > OAT menu and press INSTALLED until the value is “N.”
In the EFIS > OATSET menu, press INC- or DEC+ until the value-setting box above the menu displays the current
outside air temperature. This value is then used in the OAT/TAS/DA info item on the EFIS screen. For more information
on setting up that display, see page 5-12.
DATLOG – Logging and retrieving data
The EFIS-D10A provides two options for logging data. You may configure the EFIS-D10A to log data to its internal
memory for later retrieval or you may record streaming data serial output to an external device (such as a laptop
computer) in real-time from the EFIS serial port (as documented on page 9-2). The former option has the advantage that
it does not require an external device in the aircraft while recording. Additionally, the internal storage logs provide an
indication of alarm events, while the real-time output does not. When data logging is activated, two logs are recorded -
“all data” and “MIN/MAX”. Both logs can be downloaded using the “Retrieve Logged Data” option of the Dynon
Support Program. On certain Dynon Avionics EFIS and EMS units, a “SNAPSHOT” log is also recorded and can be
downloaded. The snapshot log records the value of all parameters anytime an alert occurs.
To activate internal data logging, enter the EFIS > SETUP > DATLOG and set RECORDING to ON. Set the
INTERVAL depending on how frequently you wish data to be stored. Data can be stored at intervals of 1, 3, 5, 10, 30,
and 60 seconds. Leaving the RECORD AT BOOT option set to NO causes the RECORDING option to be reset to OFF
every time power to the EFIS-D10A is cycled. Setting it to YES ensures that the EFIS-D10A begins logging data
automatically at boot up. If you wish to mark the data log at any point, select the MARK NOW function and press
SEL►. This inserts a notation in the data log retrieved by your PC, allowing you to quickly find the place in your data
