Harmonizing code from independent airborne aircraft identification systems
First Claim
1. An Automatic Dependent Surveillance-Broadcast (ADS-B) system for an aircraft comprising:
- a transponder decoder comprising an input adapted to receive a mode A/C transponder transmission from a transponder positioned aboard the aircraft, a decoder adapted to decode the mode A/C transponder transmission and an output for outputting the decoded mode A/C transponder transmission to determine a transponder Squawk code;
a Squawk code input that is adapted to set an ADS-B Squawk code;
a message formatter that is adapted to generate a message including the ADS-B Squawk code;
a comparator that is adapted to compare the transponder Squawk code and the ADS-B Squawk code and to inform the pilot whether the transponder Squawk code and the ADS-B Squawk code are the same; and
a wireless transmitter in communication with said message formatter, said wireless transmitter adapted to wirelessly broadcast said message including the ADS-B Squawk code.

Abstract
An Automatic Dependent Surveillance-Broadcast (ADS-B) system, and method of harmonizing a transponder Squawk code and an ADS-B system, ensures that a Squawk code broadcast by the ADS-B system matches the transponder Squawk code. The transponder Squawk code is transmitted from a transponder positioned onboard an aircraft and the transmitted transponder Squawk code with a device positioned onboard the aircraft. A Squawk code input of an ADS-B Squawk code to be transmitted with the ADS-B system is received. The ADS-B Squawk code is compared with the received transmitter Squawk code using a comparator and the pilot is informed whether the transmitter Squawk code matches the ADS-B Squawk code. A message formatter generates a message that includes the ADS-B Squawk code. A wireless transmitter broadcasts the ADS-B Squawk code generated by the message formatter.

20. A method of harmonizing a transponder Squawk code and an ADS-B system such that a Squawk code broadcast by the ADS-B system matches the transponder Squawk code, said method comprising:
-
transmitting said transponder Squawk code from a transponder positioned onboard an aircraft; receiving the transmitted transponder Squawk code with a device positioned onboard the aircraft; receiving of an ADS-B Squawk code to be transmitted with the ADS-B system; comparing the ADS-B Squawk code with the received transmitter Squawk code; informing the pilot whether the transmitter Squawk code matches the ADS-B Squawk code; and broadcasting the ADS-B Squawk code using the ADS-B system. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
