Data link technology for contingency management in super density airspace operations

•Contingency management in SDO is achieved by combining: 1. existing technologies, concepts and software (ERAM, ADS-B, AAR, Biomimicry), and 2. newly developed models (DFDI, Conflict Resolution and Mixed-mode communications for Flight Formation). •The proposed concept is demonstrated in 2D and 3D environments in strategic and tactical situations. •Improvements in efficiency, safety and aviation operations are achieved by enhancing usage of DataComm in the NextGen environment.
