Over the years, the FAA has introduced many new technologies into the National Airspace System (NAS) that have offered safety, capacity and/or efficiency improvements. However, since a number of users were often not equipped to take advantage of the new technologies, the older existing systems were continued in parallel. This has resulted in a NAS with several redundant and often obsolete systems still in operation. The operation of these multiple systems has caused FAA costs to grow at an ever increasing rate and has denied the full expected benefits to the users. Additionally, mixed aircraft equipage often results in tailoring operations to the least capable user, thus preventing operations that can reduce controller costs and provide user benefits.
