Global Aviation Consultancy Services (GACS) is an Egyptian company with an international professional team in aviation spots that serve governmental and private organizations. Since 2004 our team started to work privately in instrument flight procedures design and its related software in PANS-OPS ICAO criteria Doc. 8168. After a while our team started to focus on airspace design/planning, Annex 14 Obstacle Limitation surfaces (OLS) for Aerodrome and Heliport and aeronautical survey WGS-84 as well, these services are connected somehow with Instrument Flight Procedures design stages. Software development for PANS-OPS and OLS is one of our main services and we usually offer it with high standardization and low cost. GACS has its goal to work in the Middle East/African regions with our team that involves experts from Arab countries as well as Europe.
