  • Publication number: 20180335315
    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.

  • Publication number: 20180292954
    Abstract: Systems and methods for modifying multiple element request datalink messages in avionics system are provided. A method includes generating a plurality of downlink message element information at a verify screen displayed by a display. The method further allows for the changing of at least one downlink message element information of the plurality of downlink message element information within the verify screen. Moreover, the method concatenates the plurality of downlink message element information after the changing of the at least one element information in preparation of generating a concatenating downlink message element information message to be downlinked.

  • Publication number: 20180277116
    Abstract: A method for providing a flight display to an aircrew of an ownship aircraft includes receiving, at a radio communications module of the ownship aircraft, a voice transmission on an air traffic control first radio frequency from an air traffic controller, the voice transmission comprising a conditional clearance, wherein the condition clearance comprises a condition instruction and a clearance instruction, transcribing, using voice recognition software installed on the ownship aircraft, the voice transmission into an electronic, textual format, thereby generating a digital transmission record, and automatically, displaying, on a display device of the ownship aircraft, the condition instruction using a multi-format symbology and in a multi-step sequence over time, and waiting for and detecting an aircrew input corresponding to the clearance.

  • Patent number: 9886861
    Abstract: A system and method for dynamically validating uplink messages during flight are provided. The system comprises at least one processing unit in an aircraft, and at least one communication device in the aircraft that is operatively connected to the processing unit. The communication device is configured to receive uplink messages from a ground air traffic control (ATC) center, and transmit downlink messages to the ground ATC center. The system also includes a human machine interface (HMI) in the aircraft that is operatively connected to the processing unit. The HMI is configured to receive input from a user and display information to the user. One or more data sources that provide dynamic information are in operative communication with the processing unit. The processing unit is configured to determine whether an ATC uplink message is acceptable based on analysis of the dynamic information from the one or more data sources.
