Traffic information services-broadcast (TIS-B) automatic address detection and coverage indication
First Claim
1. A system configured for operation in an aircraft, the system comprising:
- a receiver assembly operable to receive a first transmission from a transponder associated with the aircraft, the first transmission including an identification address configured to identify the aircraft, and to receive a second transmission from an air traffic control ground station, the second transmission including air traffic information and a client list including identification addresses of aircraft included in the air traffic information; and
a processing system operable to;
retrieve the identification address associated with the first transmission; and
determine whether the aircraft is included in the air traffic information by comparing the identification address of the aircraft with the identification addresses in the client list.

Abstract
Techniques are described that allow a system, such as a portable ADS-B-enabled device, to automatically determine whether the aircraft in which the system is employed is included in air traffic information (e.g., TIS-B air traffic information) broadcast by an air traffic control (ATC) ground station. The system includes a receiver assembly to receive a first transmission from a transponder of the aircraft that includes an identification address (e.g., an ICAO address) that identifies the aircraft. The receiver assembly also receives a second transmission from the ATC ground station that includes air traffic information and a client list including identification addresses of aircraft included in the air traffic information. The identification address of the aircraft is retrieved from the first transmission and used to determine whether the aircraft is included in the air traffic information by comparing the identification address with the identification addresses in the client list.

9. A method comprising:
-
receiving a Mode S transmission from a transponder of an aircraft, the Mode S transmission including an ICAO address configured to identify the aircraft; retrieving the ICAO address from the Mode S transmission; receiving a TIS-B transmission from the air traffic control ground station, the TIS-B transmission including TIS-B air traffic information and a TIS-B service status list including ICAO addresses of aircraft included in the TIS-B air traffic information; determining whether the aircraft is included in the TIS-B air traffic information by comparing the ICAO address of the aircraft with the ICAO addresses of the TIS-B service status list; and causing an indication of whether the aircraft is included in the air traffic information to be displayed by a portable electronic device. - View Dependent Claims (10, 11, 12, 13)

14. A portable ADS-B-enabled device configured for operation in an aircraft, the portable ADS-B-enabled device comprising:
-
a receiver assembly operable to receive a Mode S transmission from a transponder of the aircraft, the Mode S transmission including an ICAO address configured to identify the aircraft, and to receive a TIS-B transmission from the air traffic control ground station, the TIS-B transmission including TIS-B air traffic information and a TIS-B service status list including ICAO addresses of aircraft included in the TIS-B air traffic information; and a processing system operable to; retrieve the ICAO address of the aircraft from the Mode S transmission; and determine whether the aircraft is included in the TIS-B air traffic information by comparing the ICAO address of the aircraft with the ICAO addresses in the TIS-B service status list. - View Dependent Claims (15, 16, 17, 18, 19, 20)
