Independent
Amend is an independent project. It isn't affiliated with or endorsed by the FAA. How it works, where the data comes from and what it doesn't cover are in the docs, and every public data file is documented there.
Not for navigation. Amend helps you notice changes. It doesn't replace official FAA publications, NOTAMs or a preflight briefing, and if Amend and the FAA ever disagree, the FAA is right.
Report a problem
Found a change that's wrong, missing or hard to understand? Email hello@amend.watch with the airport, the cycle and what the FAA source says. No account needed. On an airport page, Report a wrong change fills in the airport and cycle for you.
If Amend matches the FAA and it's the FAA's data that looks wrong, like a frequency or a chart that doesn't match the real airport, Amend can't fix it. Tell the FAA through its Aeronautical Inquiries page.
