In current air traffic operations in the U.S., closely spaced parallel runways (CSPRs) separated by less than 2500 feet (ft) can be used to conduct simultaneous parallel operations using visual separation. Once below visual approach minima, such dual runway operations are no longer possible.
The Aircraft Surveillance Applications System (ASAS) consists of an Airborne Surveillance and Separation Assurance Processor (ASSAP) and Cockpit Display of Traffic Information (CDTI). While supporting generation of the Minimum Operational Performance Standards (MOPS) for ASAS, the MITRE Corporation developed a high level functional architecture and low level algorithms for the ASSAP subsystem. The sample ASSAP algorithms have been implemented in MATLAB, along with a high fidelity representation of the CDTI. The cumulative ASAS simulation has been tested and refined with a number of data sources, including operational surveillance data from flight tests performed at the William J. Hughes [FAA] Technical Center in July of 2007 and synthesized data derived from Area Navigation (RNAV) tracks recorded at Hartsfield -Jackson Atlanta International Airport in 2006. This paper describes an abbreviated ASSAP architecture in detail and presents simulation results used to formulate the subsystem standards.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
