This question is more for th administrator or dba of the site, I'm wondering what the source is for your navaid data you show for each airport?
I know that the airport facility data comes from the NFDC facilities data.. but I haven't been able to identify the navaid source?
Anyone else know?
Suggest your question more appropriate for "Contact Us" at the page bottom. Use it to get direct, accurate answer response. If the answer is judged of general interest, the site administrator could share it via the Forum. This site is nearly two years old. The Forum started last November. Your question in the Forum could elicit a lot of speculation, guesswork, wasted space or even more such questions best directed to "Contact Us". Some Forums have a "Contact Administrator" section. In this site there is "Contact Us" that predates the Forum.

To answer csnoke's question, the navaid data on this site come from ATA-100 dataset published by FAA.
