Airside design deserves open evidence.

Mission

Transparent, reproducible, accessible.

Swept-path analysis is routine in airport planning, yet the tools that perform it have long been closed. A reviewer can see the output of such a tool but not the model behind it, the aircraft data it used, or the assumptions it made.

We started OpenAirside to change that: an engine whose every algorithm, data source and assumption is documented, and whose results can be reproduced by anyone with the input line and the aircraft type. Tractrix is how we bring that engine to the tools planners already use — QGIS, AutoCAD, Revit and the browser.

Principles

• Evidence first. Each clearance cites its clause; each steering limit cites its manufacturer document; each estimate is flagged on the output.
• Honest limits. We say what the model ignores and where it is only indicative, on the product and in the report.
• Clean data. Aircraft data is re-keyed from public facts. No vendor library, data file or software was used or reverse-engineered.
• One engine. The same computation, whichever product you use, so results never depend on the tool.
