Self-separation corridors

Abstract

This paper describes a concept called Self-

Sensitivity analysis of potential capacity and safety of flow corridor to self-separation parameters

“…In terms of the potential benefits, research has shown that sector loads and delays can be significantly reduced under very high traffic demands by creating very few corridors (8,9) . With regard to the required equipage and capabilities for aircraft, Automatic Dependent Surveillance-Broadcast (ADS-B) equipment, Performance Based Navigation (PBN) capability combining Area Navigation (RNAV) and Required Navigation Performance (RNP), Cockpit Display of Traffic Information (CDTI), and selfseparation with lane change manoeuvres have been suggested by many researchers (10,11) . With respect to the spatial configuration and optimisation, many methods including those based on Jet routes, Delaunay triangulation, traffic density, Hough transform, user-preferred vectoring and flow-based clustering are used to identify the potential corridors (12)(13)(14)(15)(16)(17)(18) .…”

Methodology for collision risk assessment of an airspace flow corridor concept

“…The aircraft shall be equipped with ADS-B to broadcast and receive state information (speed and position); the aircraft in the flow corridor shall be capable of RNP and equipped with automated separation assurance system [Alipio et al 2003, Kopardekar et al 2007, Hoffman et al 2008, Wing et al 2008, Yousefi et al 2009]. All references specify the same requirements except that Mundra and Simmons [2007] suggest that the flow corridor concept shall be capable of self separation. …”

“…Previous studies on the flow corridor concept-of-operations can be summarized into several categories: 1) Concept description, which presents the idea of flow corridors and how they operate [Alipio et al 2003, Yousefi et al 2004, 2) Geographical location, which identifies the potential routes for flow corridors [Sridhar et al 2006, Kopardekar et al 2007, Hoffman, et al 2008, Xue and Kopardekar 2009], 3) Aircraft equipage, which discusses the required equipment and capabilities of aircraft in the corridors [Mundra and Simmons 2007, Wing et al 2008, Yousefi et al 2009], 4) Regulations, which discusses the rules and procedures that aircraft should follow when flying in the corridor [Mundra andSimmons 2007, Yousefi et al 2009], 5) Benefit analysis, which shows the capacity gains that can be achieved using corridors [Wing et al 2008]. …”

Nextgen flow corridors initial design, procedures, and display functionalities

“…Many corridor concepts include the ability to specify periods of time during which a set of operational rules apply within the corridor, such as self-separation [7] or flying in formation. Clustering of aircraft or an area with increased airspace complexity may motivate the users of corridors; see [8] and [9].…”
