Our Software

Aerodrome Safeguarding
& Procedure Design Tool

Next-generation web software for ICAO PANS-OPS / Doc 8168 flight procedure design, procedure protection-area geometry and aerodrome obstacle assessment. Build OAS, full PBN SID/STAR/en-route/approach/missed approach, conventional holding/racetrack/base-turn/45-180 areas, ICAO Annex 14 OLS, OFS/OES, VSS/OCS, BRA and custom 3D surfaces in seconds — browser-based, no installation required. See ASIT modules, procedure design capabilities, pricing and FAQs for detailed capability and subscription facts. The EUR 100/month Premium plan manages up to 5 active saved airport workspaces at a time, and consulting teams can rotate through unlimited airport sites over time by exporting data, clearing one or more workspaces and starting fresh with different aerodromes under the same subscription. Each saved airport workspace can contain potentially hundreds of generated protection areas for multiple runways, OLS, VSS/OCS, holdings, racetracks and procedure surfaces.
