  • Publication number: 20200035116
    Abstract: Methods and systems are provided for flight management system (FMS) familiarization training. The system comprises a user application programming interface (API) that receives a request for a training scenario from a user. A flight management engine (FME) generates the training scenario that simulates the flight mission of an FMS onboard a designated aircraft. The training scenario is generated using the same algorithms as the FMS. A database configuration module retrieves performance and condition data that is provided to the FME for use in generating the training scenario. An external API retrieves external third-party data that is provided to the FME for use in generating the training scenario.

  • Patent number: 10515554
    Abstract: Systems and methods for time-based viewing of clearance requests are provided. The system generates a time scale of substantially a same width as a displayed lateral image and renders the time scale on a periphery of the lateral image. The system receives a recommended change to an active trajectory from one or more on-board avionics or external sources, and then time-tag processes the recommended change to predict a clearance request and its associated relevant time. The system is configured to receive a user selected future time for viewing clearance requests. Responsive to the user selected future time, the system determines that the predicted clearance request is relevant at the future time, formats the predicted clearance request as a downlink message (DM), and renders, on the time scale, the formatted predicted clearance request alongside a symbolic indicator at the future time.

  • Publication number: 20190362567
    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: 10247574
    Abstract: A system and method for determining and displaying a minimum maneuverable altitude for an aircraft to turn back includes automatically processing aircraft characteristic data, aircraft flight trajectory data, and environmental/airport services data, in a processing system, to determine a rate of change of aircraft maneuverable altitude with respect to change in aircraft heading. At least the determined rate of change of aircraft altitude with respect to change in aircraft heading is processed, in the processing system, to determine the minimum maneuverable altitude at least engine out conditions. Terrain data is processed, in the processing system, to determine a terrain clearance height above which the minimum maneuverable altitude may be implemented. The minimum maneuverable altitude is rendered, on a display device, on the altitude tape, and a pseudo gate is rendered on the display device that represents a height above the terrain that corresponds to the minimum maneuverable altitude.
