How to analyse data?

Hello,

I wonder how flight data from a Pixhawk can be analysed. Recently my quadcopter crashed after switching from "stabilize mode" into "loiter mode" for no apparent reason (not to me at least) .

I have the log/data file of the last flight, but have no clue how to translate the data into something useful.

I did go through the "common-Downloading and Analyzing Data Logs in Mission Planner" tutorial but still aren't able to draw a conclusion from the data. I just starting using MP and Pixhawk and are not very experienced with analysing data.

I'm afraid flying my quad again before I've figured out what happened.

Anybody who can help me?

Many thanks in advance!
