The interface is fully translated, and so is every written page — the guide, the learning articles, the data essays and the blog. What stays in Persian is what arrives from the data source itself: city, airport, airline and aircraft names, and the notes stored alongside them. Those will appear in Persian until the API carries an English field for them.

This system was built and produced by Omid Aminzadeh Gohari was built and developed, and access to all of its data, searches and analyses is currently entirely free .
Data and statistics

Search and Excel export

Everything you see on this page is the Aseman-jo server's response at this very moment; no sample or placeholder row is added to it. Columns the source did not report for a row stay “Unknown”.

Until a response arrives from the server, there is no file to download either.

Search filters
Observation time:Applies to the observation time of this response's rows, not to a database search — neither search service accepts a date range. Rows whose source did not give an observation time (“Unknown”) are excluded by any range other than “No limit”.
When this is on and at least two characters are typed in the search box below, the search becomes a real query with a real date range against the database — not a filter over an already-fetched response. It searches only flight number, callsign, and registration (not airport and airline), and only up to the past year, since flight rows are kept only that long.
One search across four things at once: airport names and codes, airline names and codes, aircraft registrations, and flight numbers and callsigns. At least two characters.
Altitude range (ft):The altitude filter and the emergency-code filter only work on rows whose source reported an altitude or squawk for them; “Unknown” rows are excluded by these filters, not accepted by them.
