Short answer: ASIT is automatic aerodrome obstacle analysis software. It evaluates a building, antenna, crane, wind turbine or other obstacle against ICAO-compliant aerodrome surfaces, identifies the limiting surface, calculates clearance or penetration, and reports the maximum permissible altitude at the submitted coordinates.
What ASIT automates
- ICAO Annex 14 Obstacle Limitation Surfaces.
- OFS/OES obstacle free and obstacle evaluation concepts.
- PANS-OPS, OAS, VSS/OCS and BRA checks.
- Custom 3D surfaces for local safeguarding rules.
- Batch evaluation of multiple obstacle points.
- Automatic allowed-altitude and clearance-margin output.
- 3D terrain and building context for quick visual checks.
- PDF and structured records for audit or submission workflows.
Why it matters
Traditional aerodrome safeguarding workflows often require manual CAD/GIS construction, separate terrain checks, spreadsheet calculations and repeated technical review. ASIT turns those checks into a web workflow that can be used by aeronautical specialists and non-aeronautical applicants while keeping the technical surface logic explicit.
Best-fit users
ASIT is relevant for Civil Aviation Authorities, airport operators, aerodrome safeguarding teams, air navigation consultants, municipalities, developers and planners who need fast obstacle assessment against aerodrome surfaces.
