The automatic dependent surveillance-broadcast system serves a dual role for general aviation operators, allowing integration with modern surveillance systems and providing an uplink of traffic, weather, and airspace information to participating aircraft. To obtain automatic dependent surveillance-broadcast uplink services, aircraft must be equipped with a portable or installed "automatic dependent surveillance-broadcast-in" receiver and display. This study used an online survey to assess pilot perception and valuation of automatic dependent surveillance-broadcast-in traffic and weather services, including flight information system-broadcast and traffic information system-broadcast. Of the 1407 pilot respondents to the survey, 56.3% indicated having used automatic dependent surveillancebroadcast-in traffic and weather services while operating an aircraft. Among pilots who reported using automatic dependent surveillance-broadcast-in traffic services regularly, 64.5% reported that it helped them visually acquire traffic and 42.2% felt that the automatic dependent surveillance-broadcast uplink had provided information that helped prevent a midair collision. A strong link was observed between pilot satisfaction with automatic dependent surveillance-broadcast-in traffic information and concurrent equipage with "automatic dependent surveillancebroadcast out." Pilots also reported using automatic dependent surveillance-broadcast-in weather and airspace services to improve inflight decision making, such as evaluating options for rerouting, changing altitude, or diverting to alternate airports.
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.
