How often does ADS-B broadcast an aircraft's position?

How often does ADS-B broadcast an aircraft's position?

• A. Every 10 seconds
• B. Periodically, based on satellite updates
• C. Continuously, without interruption
• D. Only during takeoff and landing

Answer: (B)

The Automatic Dependent Surveillance–Broadcast (ADS-B) system broadcasts an aircraft's position periodically, specifically based on updates from the aircraft's navigation systems. The system relays information such as the aircraft's location, velocity, and other crucial data to ground stations and other aircraft in the vicinity. The transmission interval can vary but is typically set to occur every 1 to 2 seconds during flight to ensure timely situational awareness for air traffic control and nearby aircraft. This periodic nature allows for efficient utilization of bandwidth and ensures that information remains current without overwhelming the system with continuous data. Options referring to fixed time intervals or exclusive broadcasting during specific phases of flight do not accurately reflect the operational characteristics of the ADS-B system.
