Developing safe, efficient and operationally practical instrument flight procedures for airports and heliports, in line with ICAO standards and international best practices.
GACS provides specialised instrument flight procedure design services for airports and heliports, including conventional and PBN procedures. Our designs enhance operational safety, improve airspace efficiency, and support seamless integration with the airport environment and air traffic operations.
Our procedure designers conduct complete end-to-end technical processes in accordance with ICAO PANS-OPS Doc 8168 criteria, from terrain and obstacle data collection to procedure concept formulation, precision calculation, charting, and ARINC 424 navigation data coding.
Our instrument flight procedure design services cover all phases from initial concept to final documentation, tailored to the specific operational requirements of each airport or heliport.
Design of non-precision and precision approach procedures, departures (SIDs) and arrivals (STARs) based on terrestrial navigation aids.
Design of RNAV, RNP, LNAV/VNAV, LPV and advanced performance-based procedures maximizing airspace and terminal track efficiency.
Assessment of existing and designed procedures against ICAO PANS-OPS criteria, obstacle margins, flyability, and operational criteria.
Seamless coordination with terminal airspace architecture, ATC sectorization, obstacle environments, and environmental noise requirements.
A structured and collaborative engineering approach to ensure safe, compliant, and practical flight procedures.
Airfield geodetic survey, terrain, obstacle data collection, and operational constraint review.
Formulation of procedure concepts using ICAO criteria with ATC and airline stakeholder coordination.
Full 3D obstacle clearance calculations, ARINC 424 navigation data coding, and technical reports.
Assisting clients with AIP publication, simulator validation, and periodic safety reviews.
Deliverables are tailored to specific project requirements and may include:
Our designs follow ICAO Standards and Recommended Practices (SARPs) and relevant national requirements, ensuring global best practice and operational acceptance.
