Efficient aeronautical information download coupled with ADS-B function

A computer system, comprising:

• at least one processor;
• and
• a non-transitory computer readable medium having instructions stored thereon executable by the processor to perform a method for downloading aeronautical data using an automatic dependent surveillance-broadcast (ADS-B), the method comprising:
• creating a first data sequence structure that includes a receive time for each of one or more ADS-B messages received from an aircraft;
• creating a second data sequence structure that includes a packet time for each of one or more weather data packets received from the aircraft and that are without aircraft position information;
• mapping the one or more weather data packets respectively to the one or more ADS-B messages by comparing the receive time for each of one or more ADS-B messages with the packet time for each of one or more weather data packets to produce a correlation between the one or more ADS-B messages and the one or more weather data packets;
• and
• deriving aircraft position information for each of the one or more weather data packets from each correlation between an ADS-B message and a weather data packet.

A method for downloading aeronautical data from an aircraft, the method comprising:

• determining whether automatic dependent surveillance-broadcast (ADS-B) messages are receivable from an aircraft;
• wherein when ADS-B messages are receivable from the aircraft, the method comprises:
• sending a message to the aircraft to stop transmission of aircraft position information with one or more aeronautical data packets;
• receiving one or more ADS-B messages, and one or more aeronautical data packets without aircraft position information and each with a packet time;
• storing a receive time for the one or more ADS-B messages, and the packet time for each of the one or more aeronautical data packets;
• and
• mapping the one or more aeronautical data packets respectively to the one or more ADS-B messages.
