Data Center Description
The National Flight Procedures Office (NFPO) is responsible for the global development and maintenance of both terminal and enroute instrument flight procedures. The NFPO provides lifespan maintenance of the instrument flight procedures in the National Airspace System (NAS). There are numerous types of instrument flight procedures. One example is a standard instrument approach procedure (SIAP) which is constructed to allow pilots to safely use airport runways in adverse weather. The current NAS is made up of instrument procedures based on both conventional and satellite based navigational aids. The satellite-based procedures make up approximately 20% of the NAS, but we are continuously increasing this percentage to stay in line with the new technological advancements within the aviation industry.
