1. An aircraft radar system for maintaining airspace hazard data in a given airspace comprising:

  • airspace detection equipment;

    a communication interface for engaging in communications with one or more other radar systems;

    a navigation system interface for communicating with an aircraft navigation system;

    a user interface;

    a processor;

    data storage;

    airspace hazard data stored in the data storage; and

    program instructions stored in the data storage and executable by the processor to carry out functions including;

    breaking the given airspace into a first plurality of smaller airspaces and a second plurality of smaller airspaces, wherein each of the second plurality of smaller airspaces contains two or more of the first plurality of smaller airspaces;

    detecting local airspace hazard data for each of the plurality of smaller airspaces located within a detectable range of the aircraft radar system;

    receiving remote airspace hazard data from the one or more other radar systems;
