This helps the ATC understand the actual separation between airplanes and allows controllers to avoid inefficient vectoring. Helps maintain runway approaches using a cockpit display of traffic information in marginal visual weather conditions.Įnhances visibility of all airplanes in the area to allow more airplanes to use the same runway.Īllows 5 nmi of separation in non-radar airspace compared to current procedural separation, from 5 to 3 nmi in radar airspace.ĪDS-B improves flight efficiency, and also increases throughput.

Increases runway capacity with improved arrival accuracy to the metering fix. More aircraft can simultaneously occupy this airspace while changing the separation standards.ĪDS-B significantly reduces the separation standards while maintaining safety standards, improves the accuracy and integrity of reports. All participants in the flights have a common operational picture.ĪDS-B provides more accurate and timely information than radiolocation provides more frequent updates than radar.ĪDS-B significantly improves the detection of possible conflicts and their resolution compared to any other system.ĪDS-B can provide a significant increase in the number of flights that can be serviced by the ATC. ADS-B is also effective in remote areas where there is no radar coverage or where radar coverage is limited.Īdvantages of ADS-B are as follows (Richards, O'Brien, & Miller, 2010):ĪDS-B makes it possible to maintain or improve existing safety standards while increasing the efficiency and power of the system.ĪDS-B significantly improves situational awareness of the crews, sinceĪDS-B provides an overall picture of real-time monitoring and the ability to exchange information quickly if necessary, if other aircraft deviate from their prescribed flight paths.ĪDS-B offers more accurate and more frequently updated generalized information about traffic. Unlike conventional radar, ADS-B operates at low altitudes and on land, can be used to monitor traffic on taxiways and airport runways. Navigation satellites give the exact time. ADS-B uses a combination of satellites, transmitters and receivers to provide flight crews and ground control personnel with specific information on the location and speed of aircraft in the area. For NextGen and SESAR, ADS-B technology is one of the most important in terms of converting ATC from the use of radar surveillance to the satellite global positioning system GPS. The ADS-B allows ATC to control aircraft with greater accuracy and over a much larger portion of the earth's surface than ever before. ADS-B is a new surveillance technology and is designed to modernize aviation to next generation (NextGen and Single European Sky) transport systems.
