Appendix F: User Data Logs

25-2 SkyView System Installation Guide - Revision R

Recent Flight Data Log

Filename format:

DATE-TAILNUMBER-FIRMWAREVERSION-OPTIONAL33CHARACTERS-BLACK_BOX_LOG_DATA.csv

Example:

2014-08-07-N123X-11.0-CROSS_COUNTRY_LEG1-BLACK_BOX_LOG_DATA.csv

(CROSS_COUNTRY_LEG1 is user-selectable text, up to 33 characters, at time of export.)

The Recent Flight Data Log records the most recent 15 minutes of flight at a data recording rate

of 16 times per second, in the same manner as described above. Its recording rate cannot be

changed.

The Recent Flight Data Log records data whenever SkyView believes that it is in flight, which it

determines by observing IAS and/or GPS ground speed.

Alert Data Log

Filename format:

DATE-TAILNUMBER-FIRMWAREVERSION-OPTIONAL33CHARACTERS-ALERT_DATA.csv

Example:

2014-08-07-N123X-11.0-CROSS_COUNTRY_LEG1-ALERT_DATA.csv

(CROSS_COUNTRY_LEG1 is user-selectable text, up to 33 characters, at time of export.)

The Alert Data Log contains plain-text tabular data. A new record is appended each time a

SkyView alert of any kind is triggered, including audible alerts and system messages. The Alert

Data Log is useful for diagnosing alerts that automatically clear on a brief condition, for

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

automatically clearing.

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.

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.
