22. Appendix F: User Data LogsSkyView continuously stores two retrievable data logs that can be exported for analysis. Thesedata logs are stored on SkyView’s internal flash memory and are exported to a USB memorystick.User Data LogThe User Data Log contains plain-text tabular data that records the entire state of your SkyViewsystem at a recording rate of your choosing. This includes over 100 items, and includes allADAHRS (flight instrument) data, Engine parameters, GPS data, Autopilot status, Transponderstatus, time, and more.When exported, the data log is a standard CSV (comma separated value) file and can be viewedin spreadsheet programs such as Microsoft Excel once exported from the system. The top rowof the CSV file is a header row which documents the format of the file. The headers for eachconfigurable EMS input follow the following format: Name (Units) (where the “Name” field is asit is named in the SENSOR INPUT MAPPING setup menu). Each row beneath that header rowcontains an individual record – or instantaneous snapshot – of all of the recorded fields.Because different SkyView systems have different EMS pin mappings, the order and content ofthe columns can be dynamic from system to system.The User Data Log records at the selected Record Rate (see below) any time the SkyViewsystem is powered on.A sample of what a few columns and rows of data would look like when viewed in aspreadsheet program is shown below. An actual user data log would have over 100 columns ofdata, and many thousands of rows:SystemTimeRecent Flight Data LogPitch(deg)Roll(deg)MagneticHeading(deg)IndicatedAirspeed(knots)Pressure Altitude (ft)1:50:38 0.2 -1.7 134.4 0 43641:50:38 0.2 -1.8 134.4 0 43641:50:38 0.2 -1.8 134.3 0 43641:50:38 0.2 -1.8 134.4 0 43641:50:39 0.2 -1.8 134.4 0 43641:50:39 0.2 -1.7 134.4 0 4364Table 76 - User Data Log Excerpt ExampleThe Recent Flight Data Log captures the most recent 15 minutes of flight at a data recordingrate of 16 times per second, in the same manner as described above. Its recording rate cannotbe changed.SkyView System Installation Guide - Revision O 22-1
