Do you use a database for your data? We store our flight test data as individual DATAQ files with a naming scheme. This is manageable for our very simple civil aircraft so far.
- engi_nerd 11y agoAh, a fellow flight test person. I don't handle the warehousing of data, so my knowledge is limited. I know a database is involved and used but I could not say what database or provide any specifics. Sorry. EDIT: I would like to know how other flight test people visualize their test data. Seems like you can only make so many envelope charts and strip charts (they work and are effective, but man, sometimes I'd like something different)
- nether 11y agoAll we use are strip charts. It's all I saw at Boeing as well (through some proprietary charting software IIRC). What I'd like is some "rich" time series data format that stores a history of modifications (removing noise, filtering etc.), and an overall better interface for scrolling through the data (Windaq is pretty barebones).
- engi_nerd 11y agoWow, that is pretty rough. That's so rough that I would consider figuring out some way to export your data from that software and then visualize it with python/matplotlib or similar.
- nether 11y agoI've been working on a Python module to read the files directly: https://github.com/choj/cldumpread/tree/master/WindaqReader/src https://github.com/choj/cldumpread/tree/master/WindaqReader/.... Scipy/numpy/matplotlib totally opens up what we can do with the data. The hard part is convincing a mechanical engineering manager who's extremely averse to new tools.
- engi_nerd 11y agoI've been there. Once I had to jump through huge hoops just to be allowed to install Python on a machine not connected to any networks.
- Serow225 11y agoI remember talking to someone that had an in-house flight test data warehouse with these kind of features, I think it might have been Cessna - give their FT dept a ring :)

- snowwindwaves 11y agoI use kst for plotting, transforming, visualizing, zooming, scrolling etc. It handles real time data nicely but I'm only doing 10 hz from a Plc using modbus protocol.
