Every 28 days the FAA publishes new airport, airspace and chart data. Amend compares each cycle to the last and shows what changed at every US airport in plain English: tower hours, frequencies, runways, navaids, approach plates. Build a watchlist of your airports, or share one link for a whole training area.
An iPhone app with your saved airports and cycle alerts is on the way.
Not for navigation. Always use official FAA publications, NOTAMs and a proper preflight briefing. Data: FAA NASR and d-TPP. Source
