28 © 20xx, RTCA, Inc. An aircraft is on final approach while another aircraft is stopped at the hold short line, approximately 50 m from the runway edge. The stopped aircraft begins to accelerate at 1.0 m/ sec 2 and intrudes onto the runway. An alert should be generated approximately 5 seconds before the aircraft intrudes onto the runway. 2.2.1.1.9 Aircraft Needs for Self Separation – [Flow Corridors and Self Separation Applications] The long term roadmap for ADS-B In surveillance applications is the concept of self separation where the flight crew assumes the primary responsibility for separation assurance for a defined segment of the flight and ATC assumes a secondary monitoring function. As part of their responsibility, the flight crew is granted authority to modify their trajectory within defined degrees of freedom without renegotiating with ATC. The self-separation portion of the flight generally terminates with an agreed time of arrival at the point where separation responsibility is transferred back to the ATC. The application can be implemented in either a homogeneous environment, in which all aircraft are selfseparating, or in a mixed-operations environment, in which some aircraft are receiving a separation service from the ATC. In mixed operations, ATC is not responsible for separating any aircraft where any of the relevant aircraft includes a self-separating aircraft. Per Table 2-5, this concept could require increased performance requirements that would support this category of higher integrity airborne functions. It could also potentially require the broadcast of new classes of data such as intent data and/or wake vortex parameters that are not currently required for existing categories of ADS-B In applications. 2.2.1.2 ADS-B System-Level Performance—ATS Provider Needs for Separation and Conflict Management The following discussion focuses on ground ATS surveillance and automation systems that use ADS-B surveillance information pertaining to aircraft within the area of operational control (ADS-B Out). A summary of the current ATS surveillance system capabilities is provided in Table 2-9(a). While the individual parameter values in the table may not be directly applicable to the ADS-B system, the ADS-B System is expected to support equivalent or better overall system level performance for the cited applications. ADS-B Out requirements, developed for the regional mandates, are expected to satisfy the required surveillance performance for the ADS-B In air-to-air applications. For aircraft required to support ATS surveillance in en route and terminal airspace, a capability to independently validate the ADS-B surveillance information is likely to be required [6]. Alternative validation means are under study. An example of this independent validation would be in areas of radar coverage the use of radar ranging and azimuth data to validate the received ADS-B position messages. The current en route and terminal surveillance environments consist of primary radars and SSRs providing high altitude and terminal airspace coverage. While air carrier operations generally stay within en route and terminal radar coverage, commuter, corporate, and general aviation operators frequently conduct operations that extend outside radar coverage. Existing radar technology provides surveillance performance and
capabilities that fully support the current ATS operational concepts, but the benefits in some low traffic areas do not justify the cost of a full radar system. Improved surveillance capabilities, based on ADS-B, will provide in a cost effective manner, the extended coverage necessary to support advanced ATS capabilities. ADS-B broadcasts will be received, processed, fused with other traffic management information, and provided to the system having ATS jurisdiction for that airspace. © 20xx, RTCA, Inc. 29
