Aircraft Audio Recipient Identification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft communication systems require crew members to constantly monitor and verify audio messages from air traffic control, leading to increased workload due to diverse accents, noise, and broadcast communication modes, which can be inefficient.
Innovation Solution
A method and device that automatically identify aircraft as recipients of audio communications by receiving, transcribing, analyzing, and comparing audio messages to flight data, reducing the need for crew verification through a reception unit, transcription unit, analysis unit, data generation assembly, processing unit, comparison unit, and indication unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If crew members manually monitor and verify audio messages from air traffic control, then communication accuracy can be maintained, but crew workload increases significantly
Solution Approach 1:
The system enables self-service by having the aircraft's own systems (reception unit, transcription unit, comparison unit) automatically perform message verification. The aircraft compares its own flight data with transcribed message content to autonomously determine if a message is intended for it, eliminating the need for crew manual verification while maintaining accuracy.
Solution Approach 2:
The patent replaces the mechanical human verification process with an automated electronic system. The reception unit captures audio messages, the transcription unit converts speech to text, and the comparison unit automatically compares this text with flight data, substituting the manual cognitive task of crew members with an automated information processing system.
2Reliability
If crew members constantly listen to all broadcast communications, then no relevant messages are missed, but time and attention are wasted on irrelevant communications
Solution Approach 1:
The system extracts only the relevant information from broadcast communications by comparing transcribed message content with the aircraft's flight data. The comparison unit identifies and extracts only those messages that match the aircraft's identifier, flight number, or other relevant parameters, filtering out all irrelevant communications automatically.
Solution Approach 2:
The patent introduces an intermediary automated verification system between the broadcast communications and the crew. This intermediary (comprising the transcription unit and comparison unit) acts as a filter that processes all incoming communications and presents only the relevant ones to the crew, saving their time and attention.
3Adaptability or versatility
If audio messages are received in broadcast mode, then all aircraft in the area can receive the communication, but the recipient aircraft cannot be automatically identified
Solution Approach 1:
The system performs preliminary action by pre-loading and storing the aircraft's flight data (identifier, flight number, route information) in the comparison unit before receiving communications. This preliminary preparation enables the system to quickly and automatically verify incoming broadcast messages against known aircraft parameters, enabling automatic recipient identification.
Solution Approach 2:
The patent uses copying by creating a digital text copy of the audio message through the transcription unit. This text copy can then be easily compared with the stored flight data copies in the comparison unit, enabling automatic identification of the recipient aircraft without manual intervention.

AI summary
A method and device for identification of a recipient aircraft of an audio communication. The device includes at least one reception unit, for example a VHF radio or an HF radio, for receiving an audio message on board the aircraft, a transcription unit for transcribing the audio message received into a text message, an analysis unit for analyzing the text message in order to extract interpretation data therefrom, a data generation assembly for determining flight data of the aircraft, a processing unit for determining discriminating data from these flight data, a comparison unit for comparing the interpretation data to the discriminating data so as to deduce therefrom whether the audio message received is indeed intended for the aircraft or not, and an indication unit for indicating to at least one crew member of the aircraft whether the aircraft is recipient or not of the audio message received.
