Design ICAO Annex 14 OLS, generate PANS-OPS protection surfaces and assess obstacles in 3D. ASIT brings technical safeguarding work and construction queries into one browser-based tool.
ASIT covers PANS-OPS/Doc 8168 design and OAS/PBN protection geometry for SIDs, STARs, en-route, approach and missed-approach procedures. It also supports conventional holding and turn procedures, plus Annex 14 OLS with curved surfaces for aerodromes and heliports.
ASIT stands for Aerodrome Safeguarding & Inspection Tool.
Generate and configure OLS and PANS-OPS protection surfaces, then assess proposed obstacles in one digital workflow. ASIT identifies coordinates, retrieves terrain height, calculates penetrations and prepares construction authorisation reports, replacing scattered emails and manual map checks.
Open ASIT workspaceLocate a proposed structure to see its coordinates and terrain height. View the configured approval or denial result against aerodrome surfaces and download the assessment report.
ASIT is web-based software for instrument flight procedure design under PANS-OPS, OLS generation and 3D obstacle assessment. It automates geometry, penetration checks and report preparation.
ASIT (Aerodrome Safeguarding & Inspection Tool) is a web platform for PANS-OPS procedure design, surface generation and 3D obstacle assessment. It supports PBN and conventional protection geometry under Doc 8168, OAS, Annex 14 OLS for aerodromes and heliports, OFS/OES, VSS/OCS, BRA and custom 3D surfaces. Teams can review terrain and buildings, check multiple points and see results without installing software.
ASIT brings procedure design, surface generation and obstacle assessment into one platform. It is built for procedure designers, authorities, airports and consultancy teams.
ASIT is a web-based PANS-OPS/Doc 8168 design and aerodrome safeguarding tool. Procedure designers, authorities, airports, consultancies, wind energy developers and applicants can use it to create surfaces and review buildings, cranes and other proposals.
Premium costs EUR 100 per month and includes up to five saved airport workspaces active at one time. Teams can export their data, clear a workspace and set up another aerodrome; each workspace can hold hundreds of runway and procedure protection areas.
