Welcome to Amend
Every 28 days the FAA publishes a new cycle of airport, airspace and chart data. Tower hours move, runways get renumbered, approaches get amended, and it's easy to miss.
Amend compares each cycle to the last one and tells you what changed at your airports, in plain English, up to three weeks before it takes effect.
How to read it
Remarks are the FAA's free-text airport notes. They're translated to plain English, and the original FAA text is always one tap away.
