Implementing NextGen initiatives involves complex activities ranging from concept development to deployments of capabilities in the National Airspace System (NAS).
Since June, 5 new ADS-B radio stations became operational, bringing the total to 398. Additionally, the network includes advisory services and separation services. A service volume is a defined volume of airspace in the NAS within which a set of ADS-B services are provided and the required performance for the set of services is achieved.
New service volumes were added in advisory services:
More specific localized capabilities enabled by ADS-B and a description of the three types of service volumes (En Route, Terminal and Surface) can be found on our website under technical maps.
Since May, we published new satellite-based navigation procedures:
*Note: We have modified these PBN categories to clarify that RNAV procedures include Standard Instrument Departures (SIDs) and RNAV Standard Terminal Arrivals (STARs), and that RNAV RNP are approach procedures only.
Satellite-based procedures are updated every eight weeks and are real implementations that currently provide benefits. These implemented procedures and identification of other implementations can be seen on our interactive maps.Back to Current Posting
