  • Publication number: 20200312158
    Abstract: An embodiment of a communication management unit (CMU) includes emulator and data-mining circuits. The emulator circuit is configured to generate a data request having a same format as a data request from a vehicle communications center, to send the data request to a subsystem disposed on a vehicle, and to receive data sent by the subsystem in response to the data request. The data-mining circuit is configured to provide at least some of the received data to a determining circuit configured to determine information in response to the provided data. For example, such a CMU can request flight-plan data from a flight management subsystem (FMS) by sending, to the FMS, an emulated data-request message having the same format as a data-request message from a ground-based aircraft operations center. That is, the CMU can “fool” the FMS into “thinking” that the data-request message originated from the ground-based aircraft operations center.

  • Patent number: 10755490
    Abstract: Systems and methods are disclosed for brokering data exchanges between on-board and off-board systems of a vehicle. One method comprises receiving, at a data broker engine, one or more data requests from an origination system, wherein each of the one or more data requests specifies at least one or more of a request type and a target system. Then the data broker engine determines whether the request type is a one-time transmission, a periodic transmission, an event-triggered transmission, or a change-triggered transmission. Following the determination, the data broker engine retrieves data from the target system based on the determined request type and transmits the data to the origination system.

  • Patent number: 10710743
    Abstract: Enhanced landing light systems and methods are provided. The system determines that landing lights in a landing lights assembly are on and then proceeds to identify each of the following relevant contexts: landing, taxi, and takeoff. When the aircraft is in a relevant context, the system identifies an actual travelpath and determines whether the actual travelpath matches the intended travelpath. If it does, the system generates guidance information and begins projecting the guidance information onto a landing surface. The guidance information may be digital light and comprise alphanumeric information and symbology. When the actual travelpath does not match the intended travelpath, the system generates a guidance alert and begins projecting the guidance alert onto the landing surface.
