- Gives ADS-B-equipped aircraft priority over non-equipped aircraft, including more flexible and continuous routing.
- Alleviates the requirement for position reports from ADS-B-equipped aircraft.
- Increases situational awareness, which reduces runway incursions.
- Communicates real-time traffic in the cockpit at an effective range of more than 100 miles.
- Uses both lateral and vertical guidance; transmits position and velocity data automatically for greater precision.
- Allows surveillance in remote areas that are not currently picked up on radar.
- Reduces aircraft separation, making departure and arrival times more predictable, so ATC can plan farther in advance.
- Reduces the cost of the infrastructure needed to operate air space in the United States.
- Enhances aviation safety.
- Scales and adapts for use in general aviation and in ground vehicles. Provides affordable, effective surveillance of all air and ground traffic, including on taxiways and runways.
With ADS-B, both pilots and controllers will see radar-like images with highly accurate traffic data from satellites. The images update in real-time and don't degrade with distance or terrain. Pilots with access to this information will have improved situational awareness so they're able to fly closer to other aircraft while maintaining safe distances, and they'll need less assistance from ATC.
Because ATC has a better picture of the traffic they are managing, they're able to eliminate wasted space between aircraft. This, in turn, increases aircraft capacity in the air and decreases the need for holding patterns. It will also allow the use of Continuous Descent Approach (CDA), which calls for an aircraft to descend at idle thrust from cruising altitude to landing. CDA procedures aim to reduce fuel burn and emissions. ADS-B, combined with the increased position precision of GPS RNP procedures, will save operators time and money by shortening their time in the air.
ADS-B was designed to be much less expensive to set up and maintain than the infrastructure currently in use, so our nation's air system can increase capacity and safety while staying on a budget. It also allows for full United States coverage as ground stations can be located in remote locations such as the Alaskan outback or on offshore oil rigs in the Gulf and Hudson Bay.
The gains in safety, capacity and efficiency that result from a satellite-based system will enable the FAA to meet predicted air traffic growth. And because ADS-B is a flexible and expandable platform, it can change and grow as needed.
