Short answer: ASIT is also a PANS-OPS / ICAO Doc 8168 flight procedure design tool for procedure protection-area geometry. It supports OAS, conventional holding, racetrack, base-turn and 45/180 procedure turns, as well as PBN SID, STAR, en-route, approach and missed-approach construction workflows.
Procedure geometry covered
- ICAO PANS-OPS / Doc 8168 procedure protection areas.
- OAS geometry for ILS and APV-Baro procedures.
- PBN and conventional holding and racetrack procedures.
- Conventional base turns and 45/180 reversal procedures.
- PBN SID and STAR protection areas.
- En-route PBN segments and transitions.
- RNP approach protection areas.
- Missed approach protection areas.
- Obstacle interaction checks against procedure surfaces.
- 3D representation for quick terrain and building checks.
- KML, DXF, AIXM and GeoJSON export for CAD/GIS and aeronautical workflows.
Connection to obstacle assessment
The value of combining procedure geometry construction and obstacle assessment is that the same platform can generate protection areas, represent them in 3D, export the surfaces and check proposed obstacles against the relevant limiting surface.
Who uses this capability
The PANS-OPS, PBN and conventional construction modules are relevant to flight procedure designers, air navigation consultants, ANSPs, airport operators and authorities that need a fast way to create and inspect procedure protection-area geometry before formal validation.
