  • Patent number: 9921823
    Abstract: An improved integrated avionics system having a plurality of line replacement units (LRUs) is disclosed. At least one LRU stores in its memory software and configuration data stored and used by another LRU in the system. Upon detecting a new LRU installation, the at least one LRU may be configured to copy to its internal memory the software and configuration data loaded to the new LRU. The LRU may also store a table in its internal memory identifying each LRU that has been installed in the system, when each LRU was installed, and a copy of configuration and software data loaded to each LRU. If one of the LRUs in the system needs to be replaced, the LRU may determine which software and configuration data is applicable to the replaced LRU and load the determined software and configuration data to the new LRU, thereby improving the loading and installation process.

  • Patent number: 9437112
    Abstract: Techniques are described that allow an air traffic display of an aircraft to display the relative motion of air traffic proximate to the aircraft. The air traffic display may be switched between a first display mode in which absolute motion of air traffic is displayed (e.g., motion of air traffic targets relative to a fixed point on the earth's surface or relative to an apparently fixed celestial point is displayed) and a second display mode in which motion of air traffic targets is displayed relative to the aircraft. The techniques further facilitate the selection of individual traffic targets from a displayed traffic depiction to activate a third display mode in which additional information about the relative motion of the selected target, such as its estimated closest point of approach (CPA) to the aircraft and the estimated time it will take the selected target to reach the CPA are shown.

  • Patent number: 9418559
    Abstract: Techniques and systems are described that allow an air traffic display and/or avionics system of an aircraft to display and/or warn a pilot of aircraft targets for air traffic proximate to the aircraft or to suppress the display of on-ground air traffic targets. In some implementations, an integrated avionics system can use indirect information to determine whether an individual aircraft traffic target is to be presented to a pilot. For example, the integrated avionics system can determine whether an aircraft target is in proximity to the ground based on traffic tracking data corresponding to other aircraft.
