Thanks for the sample thats helped. If anyone else is having trouble with this, the problem was that when I created the .csv file from the spreadsheet it wanted to put commas & quotations around everything. I needed to force it to drop the quotations.

Anyone else having trouble getting custom data to load at start up? Loads fine on import now!

No worries. We've actually created a graphical tool that makes it really easy to create SkyDemon data. Would you like to try a preview of it? If so, let me know by contacting me directly using the link at the bottom of the homepage and I'll email you a copy.

Thanks for that Tim. I give it another try & report back. Sorry its taken a few days to reply, I don't get regular access to internet here in Africa!

Sure. Here's a file with three navaids from the UK data.

As a first attempt I was trying to make a file for naviads. Once thats successful I intend to start building up the rest of the data for the area I fly (central Africa) i.e. airfields, airspace

Sure, what data were you interested in? Airfields, obstructions?

Does anyone have a sample custom data .csv file I could look at? I had a go at creating my own data file as per the tutorial, i.e. entering some data in a spreadsheet, then converting it to .csv, but the Skydemon software says 'input string not in correct format'. Just thought if I could see a file that works, I could work out what was wrong & correct it.

Thanks
