Presented herein are systems and methods for simulating translated aircraft terminal procedures and comparing them to detect for errors in the translation of the terminal procedures. In one or more examples, one or more regulatory agency's routes and procedures for a given airspace are translated into one or more instructions that can be read by a flight computer that is configured to assist a pilot during a flight to adhere to those agency's procedures. A given terminal procedure can have multiple translations associated with it. In order to determine the accuracy of the translation process, in one or more examples, the translations provided by those vendors can be simulated by a computer that is configured to simulate an aircraft's traversal of an airspace using the instructions loaded on to the flight computer. The data generated by the simulations can be used to compare the translations to detect errors in the translation process.

A system and method provide improved remote turbulence measurement. The system includes an image capturing device that captures time-lapse images of a distant target anywhere from a km to more than a 100 km away. A processor of the system tracks relative motion due to atmospheric turbulence of some number of patches of definite size on each of these images using a subpixel accurate correlation technique. The processor computes differential tilt variances between every pair of patches from the image collection and evaluates the theoretical weighting functions between turbulence along the path and differential tilt variances. The processor determines weights to linearly combine the weighting functions such that the combined weighting function closely resembles the weighting function corresponding to a turbulence parameter of interest. The processor then combines the differential tilt variances using the determined weights to obtain the desired turbulence parameter.

The processor may be configured to: receive a lead aircraft assignment instruction, the lead aircraft assignment instruction instructing the aircraft to follow a lead aircraft; determine whether the aircraft is receiving sufficient lead aircraft traffic data from the lead aircraft to record a four-dimensional (4D) track of the lead aircraft; upon a determination that the aircraft is receiving the sufficient lead aircraft traffic data, output an acceptance of the lead aircraft assignment instruction; receive the lead aircraft traffic data from the lead aircraft, the lead aircraft traffic data including information at least one of associated with or of the track of the lead aircraft; record the track of the lead aircraft; and output commands configured to cause (a) the aircraft to follow the recorded track, or (b) guidance content for following the recorded track of the lead aircraft to be presented.

A system for extracting speaker information in an ATC transcription and displaying the speaker information on a graphical display unit is provided. The system is configured to: segment a stream of audio received from an ATC and other aircraft into a plurality of chunks; determine, for each chunk, if the speaker is enrolled in an enrolled speaker database; when the speaker is enrolled in the enrolled speaker database, decode the chunk using a speaker-dependent automatic speech recognition (ASR) model and tag the chunk with a permanent name for the speaker; when the speaker is not enrolled in the enrolled speaker database, assign a temporary name for the speaker, tag the chunk with the temporary name, and decode the chunk using a speaker independent speech recognition model; format the decoded chunk as text; and signal the graphical display unit to display the formatted text along with an identity for the speaker.
