Abstract: The technology generally relates to determining a status of an optical channel between two components. For example, the components may be connected via an optical link including a plurality of optical channels. A first portion of the optical channels may be in use such that a second portion of the optical channels may be redundant channels. The component may include a test generator that transmits and receives a data pattern over each channel. The test generator may determine, based on the received data pattern, a status of each of the channels. If the status of a given channel is a failure status, the component may divert data for the given channel to a redundant channel.

Abstract: Methods and systems are provided for assisting operation of an aircraft by automatically using a specified value contained in a message. One method involves obtaining a first set of one or more attributes associated with a runway from a first data source, obtaining status information associated with the aircraft from a second data source, obtaining, over a network, a message relevant to the runway from an external data source, analyzing the message to automatically identify a second set of one or more attributes associated with a condition of the runway, determining a location of a reference point associated with the runway based at least in part on the status information in a manner that is influenced by the second set of one or more attributes from the message, and providing, on a display device, an indication influenced by the location of the reference point.

Abstract: Systems and methods for calibrating a synthetic image on an avionic display. The method includes receiving a synthetic image frame generated by an avionic display system and a sensor image frame from a forward-facing onboard sensor system. Object recognition is performed on the sensor image frame to generate a first search region for a first Federal Aviation Administration (FAA) marking, defined as a first search region-FAA marking pair. The sensor image frame and the first search region-FAA marking pair are processed using a deep learning method (DLM) to determine for the first FAA marking of the first search region-FAA marking pair, each of: a position deviation calculation, an orientation deviation calculation, and a synthetic image distortion factor. The synthetic image frame is then updated and rendered in accordance with the position deviation calculation, the orientation deviation calculation, and the synthetic image distortion factor, thereby calibrating the synthetic image frame.

Abstract: Methods and systems of determining and displaying a taxiing route on an airport moving map. The methods and systems include computer implemented steps of: deriving a location of the ground traffic with respect to taxiways or runways at an airport and a direction of travel of the ground traffic, executing a route planning algorithm for determining a route including one or more taxiways and runways from an aircraft location to the taxi destination using, as inputs, airport data from an airport mapping database, the location of the ground traffic, the direction of travel of the ground traffic, and a taxi destination, and generating a display for the display device including an airport moving map based on airport data from the airport mapping database and including a graphical depiction of the route on the airport moving map.

Abstract: Methods and systems are provided for propagating a free-form user input across different displays. One method involves receiving a free-form user input on a navigational map display, assigning a geographic location to the free-form user input based on a position of the free-form user input on the navigational map display, and generating a graphical indication influenced by the free-form user input on a second display at a respective position on the second display corresponding to the geographic location assigned to the free-form user input.

Abstract: A method for displaying objects in an aerial vehicle is disclosed. The method includes: determining if sensed objects or calculated virtual objects around the travel path of the aerial vehicle are within a field of view of a three-dimensional view in front of the aerial vehicle displayed on a display screen in the aerial vehicle; selecting, for each graphical object representing an object within the field of view of the three-dimensional view, a graphical object display size for the object, wherein the display size of an object is determined based on a non-linear projection per distance between the object and the view point that is scaled based on a continuous, non-linear scaling function, which causes the object to be displayed smaller at certain distances and larger at other distances than it would if linear scaling alone were applied; causing the display of the one or more graphical objects with the selected display size.

Abstract: Systems and methods are disclosed that receiving ground traffic data from a traffic computer, and enhanced vision system, EVS, imaging data from at least one EVS camera. A target area is determined in the EVS imaging data based on position data of the ground traffic data. Graphics processing is performed that is confined to the target area to enhance visibility of ground traffic in the EVS imaging data in the target area, thereby generating enhanced EVS imaging data. The graphics processing is selected from at least one of contrast enhancement, edge detection and template matching and highlighting of an outline of the ground traffic. A display is generated that is to be displayed on the display device based on the enhanced EVS imaging data and the EVS imaging data.

Abstract: The present disclosure relates to aircraft display systems and methods for providing ground traffic collision threat awareness. Traffic data is received, optionally from an automatic dependent surveillance broadcast, ADSB, system, including location data for other vehicles. Threat level data is determined representing an urgency of a threat of a surface collision with another vehicle based on the traffic data. The threat level data and the location data for the another vehicle is encoded into graphical symbology for a primary flight display device and into graphical symbology for a navigation display device. The graphical symbology is displayed on the primary flight display device and on the navigation display device.

Abstract: Methods and systems are provided for adjusting a dynamic scale indicator on a flight display of an aircraft. The method comprises receiving an operational status parameter for the aircraft and generating the dynamic scale indicator located on the flight display of the aircraft. The dynamic scale indicator includes a positive value range that represents operational status parameter values greater than a selected setting value and a negative value range that represents operational status parameter values less than the selected setting value. The operational status parameter is translated into a value that is represented on the dynamic scale indicator. The value ranges shown on the dynamic scale indicator are adjusted by fading the negative value range when the operational status parameter value is positive, fading the positive value range when the operational status parameter value is negative, and fading the value range to the extent that the value range exceeds the operational status parameter value.
