Hi, To view and check flight data we try to use Flight Data - Open Data Viewer.  In data viewer on the top there is the "folder" button - we open that and see the flight records in the Sd card.  When you open one of the flight record files, it does lots of opeining but there is nothing on the screen.  Is there some type of tutorioal that one can use to check the flights please?

I have checked again and really cannot find something relevant from 2017 or 2018 - all the posts I can find are from 2015 etc and are not relevant anymore.
