example, oil pressure going into the red zone for a few seconds, then back into green, and

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. Each record consists of
supporting data such as time, GPS data, type of alert, the type of alert action, and the
description of the alert. The Alert Data Log is allocated 2 MB which may be sufficient to record
more than 1500 hours of operation assuming as many as 10 alerts per hour. The Alert Data Log
is not affected by the RECORD RATE setting below.
History Data Log

Example:
2014-08-07-N123X-SN1492-11.0-CROSS_COUNTRY_LEG1-HISTORY_LOG_DATA.csv
(CROSS_COUNTRY_LEG1 is user-selectable text, up to 33 characters, at time of export.)
The History Data Log is a cumulative history of files loaded onto the SkyView and other changes
mostly used for troubleshooting when requested from Dynon Avionics Technical Support.
Data Logging Recording Options
Record Rate
You can choose the frequency of the data that is recorded from SkyView’s various systems for
your particular needs. SkyView can record data as frequently as 16 times per second or as
infrequently as once every 10 seconds. Recording more frequently trades off the amount of
time that the data log covers. At once every 10 seconds, SkyView’s User Data Log can store up
to about 150 hours of data. At 16 times per second, the log stores about 2 hours of data. When
the data log fills up, the oldest data is automatically discarded to make room for new data.
Navigate to SETUP MENU > SYSTEM SETUP > DATA LOG SETUP > RECORD RATE to choose the
frequency that data is recorded to the internal User Data Log.
Clearing Data Logs
Navigate to SETUP MENU > SYSTEM SETUP > DATA LOG SETUP > CLEAR ALL DATA to erase the
User Data Log, Recent Flight Data Log, and Alert Data Log.
Exporting Data Logs
In a dual engine configuration (dual SV-EMS-22x with at least two SkyView
displays), data logs for each engine are recorded / exported only on the display
that is monitoring each engine. Example – in a system where the left display is
configured to monitor the left engine, the data log exported from the left display
