25. Appendix F: User Data Logs
SkyView continuously stores four retrievable data logs that can be exported for user analysis.
These data logs are stored on SkyView’s internal flash memory and are exported to a USB flash
drive.
The base file name is the same on all four logs. Each element is separated by a dash (-)
character:

DATE – Expressed as year (-) 2 digit month – (2 digit day). Example 2015-01-14

TAILNUMBER – As entered into SETUP MENU > SYSTEM SETUP > AIRCRAFT
INFORMATION > TAIL NUMBER

SKYVIEWDISPLAYSERIALNUMBER – The serial number of the SkyView display the
datalogs were recorded from. Expressed as SNxxxxx (4 digits for SV-D700/SV-D1000, 5
digits for SV-D1000T).

FIRMWAREVERSION – The firmware version on the SkyView display that the datalogs
were recorded from, at the time of the datalog export.

OPTIONAL33CHARACTERS – Optional 33 user-selectable characters that can be added to
the datalogs filename, selectable at the time of the datalogs are exported.

PART_XX – SkyView may save a datalog into multiple files, distinguished by sequential
digits, such as ….PART_01, ….PART_02, etc.
User Data Log
Filename format:
DATE-TAILNUMBER-SKYVIEWDISPLAYSERIALNUMBER-FIRMWAREVERSION-
OPTIONAL33CHARACTERS-USER-LOG-DATA.csv
Example:
2014-08-07-N123X-SN1492-11.0-CROSS_COUNTRY_LEG1-USER_LOG_DATA.csv
(CROSS_COUNTRY_LEG1 is user-selectable text, up to 33 characters, at time of export.)
The User Data Log contains plain-text tabular data that records the entire state of your SkyView
system at a recording rate of your choosing (see below). This includes over 100 items, and
includes all ADAHRS (flight instrument) data, Engine parameters, GPS data, Autopilot status,
Transponder status, time, and more.
When exported, the data log is a standard CSV (comma separated value) file and can be viewed
in spreadsheet programs such as Microsoft Excel once exported from the system. The top row
of the CSV file is a header row which documents the format of the file. The headers for each
configurable EMS input follow the following format: Name (Units) (where the “Name” field is as
it is named in the SENSOR INPUT MAPPING setup menu). Each row beneath that header row
contains 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 of
the columns can be dynamic from system to system.
