ADS-B is an automatic dependent surveillance-broadcast system used to transmit information about an aircraft or airport vehicle’s identity, position, and other related details from onboard systems. The technology enables air traffic control and pilots to have situational awareness and separation, thus improving flight safety and efficiency.
Benefits of ADS-B
ADS-B offers numerous advantages, including:
- Improved safety and efficiency for pilots and air traffic control
- Automatic surveillance without external constraint
- Reliance on onboard systems to provide surveillance information
- Transmits data without knowing who is receiving the data
- No mutual interrogation or contract
- Key technology for achieving Single European Sky and next-generation performance goals
- Less expensive to install and operate compared to primary and secondary radar systems
- No subscription fees charged in the U.S. for ADS-B services
ADS-B In enables pilots and air traffic control to view traffic information about surrounding aircraft. The information includes altitude, heading, speed, and distance to the aircraft. ADS-B Out subscribers provide position reports, while TIS-B can provide position reports on aircraft not equipped with ADS-B Out if suitable ground equipment and ground radar are available.
UAT ADS-B In technology-equipped aircraft can receive weather reports and information related to temporary flight restrictions and NOTAMs. The Flight Information Service (FIS-B) transmits weather radar information in the U.S.
The aircraft owner pays for the equipment and installation costs, while the FAA manages and transmits all ADS-B services in the U.S.
Frequently Asked Questions (FAQ)
What is the difference between ADS-B In and ADS-B Out?
ADS-B Out is the transmission of data from an aircraft’s onboard systems, while ADS-B In is the receipt of ADS-B Out information by other aircraft or air traffic control.
Why is ADS-B vital for achieving performance goals in aviation?
ADS-B is seen as key to the future ATM network on both sides of the North Atlantic and elsewhere, and is critical to achieving Single European Sky (SES) and next-generation performance goals, including safety, capacity, efficiency, and environmental sustainability.
Is there a subscription fee for ADS-B services in the U.S.?
No, there is no subscription fee. The aircraft owner pays for the equipment and installation, while the FAA manages and transmits all ADS-B services.
Conclusion
ADS-B is an innovative technology that provides pilots and air traffic control with vital information, including identity, position, and other aircraft-related details. The system improves safety and efficiency, making it a critical component for achieving Single European Sky and next-generation performance goals. ADS-B is much less expensive than traditional radar systems and is a cost-effective solution for both pilots and air traffic control.
