Solution Overview
Problem
Existing aircraft navigation systems lack the ability to quickly and accurately identify and assess relevant visual information in the environment, particularly for general aviation applications, necessitating improved display systems for pilots.
Innovation Solution
Aircraft navigation systems that translate audible aviation broadcasts into text form and display this information graphically, with features like highlighting out-of-ordinary conditions, user-actuatable interfaces, and customizable annotations to enhance pilot awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If audio broadcasts are converted to text and displayed graphically, then information accessibility is improved, but processing complexity increases
Solution Approach 1:
The system uses speech-to-text conversion as an intermediary process between audio broadcasts and visual display. The audio signal is first converted to text data, which is then processed to extract information elements. This intermediary step enables pilots with visual impairments or those preferring text-based information to access broadcast content effectively.
Solution Approach 2:
The system replaces traditional audio-only information delivery with an automated speech-to-text and graphical display system. Instead of relying solely on auditory processing, the system uses automated conversion and visual presentation to deliver information, reducing the need for manual note-taking or audio monitoring.
2Reliability
If multiple information elements are extracted and displayed, then situational awareness is improved, but display complexity increases
Solution Approach 1:
The system segments broadcast information into distinct information elements such as airport identifiers, weather conditions, runway information, and NOTAMs. Each element is extracted and displayed separately with appropriate labeling, allowing pilots to quickly scan and understand specific aspects of the broadcast without being overwhelmed by a wall of text.
Solution Approach 2:
Different information elements are displayed with different visual characteristics based on their importance and type. Critical information may be highlighted or positioned in prominent locations on the display, while less critical information is presented in a standard format. This allows the display to adapt its quality and presentation based on the local requirements of each information element.
3Loss of time
If real-time conversion and display is implemented, then information timeliness is improved, but processing speed requirements increase
Solution Approach 1:
The system performs preliminary processing of the audio broadcast by converting it to text and extracting information elements in real-time as the broadcast is received. This preliminary action ensures that the information is ready for display immediately, minimizing any delay between the original broadcast and its presentation to the pilot.
Data Source
AI summary
A method for operating a computing system including one or more processors to provide a visual display of received audible broadcast information on an aircraft. Embodiments include receiving an audible aviation broadcast, translating the broadcast into text data, extracting one or more information elements from the text data, and displaying the one or more information elements in graphical form on a visual display in the aircraft. Some embodiments include displaying the information elements in text form along with associated descriptors of the information elements. Examples of the audible aviation broadcasts include an Automatic Terminal Information Service (ATIS) broadcast, Automated Weather Observing System (AWOS) broadcast, Automated Surface Observing System (ASOS) broadcast, Notice to Air Missions (NOTAM) broadcast, Significant Meteorological Information (SIGMET) and Airman's Meteorological Information (AIRMET) broadcast.
