Abstract: A system, method, and indicator for distributing, generating, and presenting relative locations of points of interest to a viewer are disclosed. A distribution system may include a discovery datagram generator and a flight navigation datagram generator for broadcasting a discovery datagram and flight navigation datagram, respectively, to a portable electronic device (PED), where the flight navigation datagram may be comprised of navigation data representative of flight navigation information. A generating method may be performed by the PED configured to listen for and receive the discovery datagram; listen for and receive the navigation datagram continuously; and generate a display data set representative of the indicator continuously, where the indicator includes a directional pointer, a first rounded indicator, a second rounded indicator, and one or more location indicators, where each location indicator indicates a relative bearing to a point of interest measured with reference to the directional pointer.

Abstract: Present novel and non-trivial system, device, and method for the distribution of in-flight information to a portable electronic device (“PED”) are disclosed. The system could be comprised of a cabin entertainment unit and one or more PEDs, where the cabin entertainment unit could be a device comprised of a discovery datagram generator, a flight navigation datagram generator, a file transfer protocol/hypertext transfer protocol (“FTP/HTTP”) server storing a custom map configuration file, and/or a trackline data generator. A discovery datagram could provide a plurality of network addresses from which the PED may listen for and receive flight navigation datagrams repeatedly, request and receive the custom map configuration file, and request and receive trackline data representative of the ground track already flown by the aircraft.
