Precision aerodrome safeguarding, 3D obstacle limitation surface modeling, and penetration evaluations in accordance with ICAO Annex 14 standards.
Aerodrome Safeguarding is the vital engineering procedure by which the protected airspace surrounding an airport or heliport is managed and systematically kept obstacle-free. GACS provides comprehensive OLS development and safeguarding assessments in strict accordance with ICAO Annex 14 standards and national civil aviation regulations.
Utilizing specialized Geo-Design Annexes software, our technical team establishes precise three-dimensional mathematical surface models to evaluate existing terrain, proposed real estate developments, crane operations, and infrastructure projects, ensuring uninterrupted flight safety during take-off and landing operations.
Our obstacle limitation surface services protect vital flight paths through rigorous 3D spatial assessments, safeguarding frameworks, and authority coordination.
Complete 3D CAD modeling of Approach, Take-off Climb, Transitional, Inner Horizontal, Conical, and Balked Landing surfaces.
Comprehensive mathematical identification and quantification of natural terrain and man-made structure intrusions into protected airspace.
Formulating structured safeguarding frameworks, maximum permissible building heights, and formal liaison protocols with planning authorities.
Dedicated obstacle limitation surface calculations for surface-level, elevated, and helideck facilities according to ICAO Annex 14 Vol II.
A systematic approach to evaluating, modeling, and protecting vital aerodrome operational airspace.
Runway thresholds, elevation datums, classification code, and baseline geodetic survey data verification.
Precision 3D modeling of Annex 14 OLS surfaces utilizing proprietary Geo-Design Annexes software.
Cross-referencing topographical lidar/survey data and proposed construction coordinates against OLS limits.
Delivering official penetration tables, maximum allowable height zoning maps, and mitigation reports.
Deliverables are tailored to specific aerodrome safeguarding requirements and include:
Our OLS assessments strictly comply with ICAO Annex 14 (Volumes I & II), ICAO Doc 9137 (Airport Services Manual – Part 6), and national aerodrome regulations.
