There's a data log that you can export that in SETUP MENU > SYSTEM SOFTWARE > EXPORT USER DATA LOGS. That gets you a CSV file that has as much data as SkyView can hold, which can be between a couple and 150 hours of historical flight data, depending on how often you have SkyView set up to record data. The data's pretty raw (it's a CSV file), but some of our customers have made tools that are designed to give you insights into that data. See this thread for some of the discussion:

Also, https://www.savvyanalysis.com was built for engine analysis, but it also has the ability to
create flight logs from your uploaded Dynon data logs. A lot of Dynon customers are Saavy Analysis users.
