Self-separation corridors

Abstract

This paper describes a concept called self-separation corridors (SSCs). This is an automatic dependent surveillance - broadcast (ADS-B) application that establishes self-separation corridors in high-altitude en route airspace. This concept enables traffic managers to create high-density corridors along specific airspace segments for suitably equipped aircraft for use during heavy sector congestion or limited access due to severe weather. An SSC is defined as a set of parallel routes in close proximity to one another, in which crewmembers accept responsibility for separation from other aircraft in the corridor. While in an SSC, pilots use on-board instrumentation to ensure proper spacing behind the lead aircraft. The on-board instrumentation also provides protection from deviations or blunders by aircraft on the parallel routes. This paper describes the primary SSC concept, proposed solutions, and suggested areas of research.
