EGFD is the current and correct code for Llandbehr. EGOD is the old code.
Edit: Navigraph’s data comes from a real-world provider, and will always contain current data; when in doubt (about airport code changes specifically), it’s simple: Navigraph’s database is correct and whatever other contradicting source you found is incorrect/outdated
No, not at the moment - but a good idea. I will add this wish to our feature-list … to compare the MSFS data with the real-world data. At the moment, the workload is a little bit too high, but possible during the free Christmas days … I will mark your posting here, and will inform you, when I have such a list.
Wikipedia is 50/50 I guess, I would not trust it either. Navigraph’s data and charts aren’t always 100% bug-free, but I don’t think I ever saw a case where an airport code was out of date. Using the Charts application as a reference really is the better option here.
