I just started a Pro subscription to Savvy.  I am struggling to understand the flight log names so I am asking for advice on how to understand and manage the data.

I cannot seem to discern easily what date and time the flight was on by looking at the stack of file names on the Savvy website and what they mean.  It seems that each time I turn on Skyview it is showing as a "flight".

Some of the file names have the same date and Z time but they all have slightly different file names...some are called "Black Box" so can someone please give me some tips on how to name these files to make heads/tails of what is going on???

Here is what the stack look like:

2018-02-14 19:28  SN2295-15.2.0.4389-BLACK_BOX_LOG_DATA.csv            
2018-02-14 19:14  SN2295-15.2.0.4389-USER_LOG_DATA-PART_04-6.csv      2018-02-15 19:14  SN2295-15.2.0.4389-USER_LOG_DATA-PART_04.csv                  
2018-02-06 22:22  SN2295-15.2.0.4389-USER_LOG_DATA-PART_04.csv                  
2018-02-06 22:22  SN2295-15.2.0.4389-USER_LOG_DATA-PART_04-2.csv            
2018-02-06 22:22  SN2295-15.2.0.4389-USER_LOG_DATA-PART_04-3.csv                  
2018-02-06 22:22  SN2295-15.2.0.4389-USER_LOG_DATA-PART_04-4.csv            
2018-02-06 22:22  SN2295-15.2.0.4389-USER_LOG_DATA-PART_04-5.csv                  
2018-02-06 22:22  SN2295-15.2.0.4389-USER_LOG_DATA-PART_04-6.csv            
2018-02-06 22:22 SN2295-15.2.0.4389-USER_LOG_DATA-PART_04.csv

THANKS!!!

I believe every time you update the software OR change the configuration file (change the ENGINE display settings) Skyview creates a new USER_LOG_DATA_PART file. They are numbered. Unless you are looking for something specific that happened in the last 15 minutes of the last flight then the USER_LOG_DATA_PART file are the ones you want. The BLACK_BOX_LOG_DATA is the last 15 minutes of the last flight you took and is recorded at 16 times a second (16Hz). There is only one file as it is a rotating file with the last 15 minutes of data. You can also upload it for analysis but for some reason that didn't work for me when I needed it. It was considered a NON flight. That was a while ago.

You can ignore any of the USER_LOG_DATA_PART files that are small (byte size). They probably don't have flights in them. They are created when you turn on Skyview and then turn it off without any flight time. If you changed something in Skyview it'll create a new USER_LOG_DATA_PART_XX file. I ended up with a ton of PART_XX files the last time I messed with the ENGINE settings.

You can upload all the USER_LOG_DATA files to Savvy. In the FLIGHTS pages all the REAL flights will be listed. You can delete any flights listed that you know are not real flights. I think Savvy is doing a better job of not listing non flights but they do show up when you go Previous or Next Flight.

You can also delete any flights that show up as duplicates on Savvy. This happens if you downloaded your USER LOGS but didn't delete them from Skyview. The next time you download and then upload them to Savvy you will have duplicate flights.

Savvy doesn't have any limit on the number of files that you can have stored on their web site. I have 844 flights listed under my account. I systematically upload all my USER LOGS even if I don't use them for analysis. I believe they use the data for BIG DATA analysis. In one article they did an analysis of what the percentage of flight were against the wind as opposed to with the wind. According to Savvy you are correct in thinking that you fly into a wind more often than with the wind. They had a reason but I can't remember what it was. Poor flight planning maybe? Grin Grin
