GACS developed two software to automate the criteria that generate technical designs (Areas dimensions, calculations, 3D surfaces, etc.) for our services like instrument flight procedures, obstacle data base, geo coordinates, obstacle limitation surfaces, PAPI, Charts, etc. These software programs comply with ICAO criteria and in some cases the software permits changing inputs by user to accommodate his organization recommendation for the purpose of improved safety in such critical cases. Refer to Software section to read more about our software details.
