Solution Overview

Problem

Pilots face challenges in accurately memorizing and executing taxiing instructions from air traffic control, leading to potential aircraft damage due to restricted taxiways not being clearly communicated.

Innovation Solution

A method that converts audio communications between pilots and air traffic control into text, uses a look-up table to check for obstructions in the taxi path, and issues warnings if obstructions are detected, displayed on cockpit displays or through audio alerts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pilots rely on memorizing taxiing callouts from air traffic control, then the system remains simple and requires no additional equipment, but pilots may mistakenly enter restricted taxiways leading to aircraft damage

Engineering Contradiction:
Improvetaxi path accuracyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary system (electronic device with obstacle data database) that mediates between the pilot and the taxi environment. This intermediary automatically checks taxi paths against stored obstacle information, eliminating the need for pilots to manually memorize restricted areas while providing automated safety verification.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary actions by pre-storing obstacle and restricted area data in an electronic database before taxiing operations. This allows the system to proactively identify and warn about potential hazards before the aircraft actually enters restricted areas, rather than relying on pilot memory or reactive measures.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If pilots are provided with detailed taxiway restriction information, then safety improves, but the information load on pilots increases and may lead to confusion

Engineering Contradiction:
Improvetaxi path safetyVSAvoidpilot workload
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The electronic device performs self-service by automatically accessing its internal obstacle database, processing taxi path information, and generating warnings without requiring pilot intervention. The system independently manages the complex task of cross-referencing current position with restricted areas, freeing pilots from information processing burdens.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback by providing real-time warnings to pilots when potential taxi path conflicts are detected. This closed-loop feedback mechanism continuously monitors taxi progress and immediately alerts pilots to hazards, enabling corrective action before mistakes occur.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If real-time taxi path monitoring is implemented, then obstruction detection improves, but system complexity and computational requirements increase

Engineering Contradiction:
Improveobstruction detection accuracyVSAvoidmonitoring system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system creates a simplified digital copy of the physical taxi environment by storing obstacle and restricted area data in an electronic database. This virtual representation allows for efficient computational comparison with actual taxi paths without requiring complex real-time sensing or processing of the physical environment.

Inventive Principle:
Principle #26Copying

AI summary

A method includes converting audio to text, converting the text to a taxi path, and using a look-up table (LUT) to check for obstructions in the taxi path. The method includes issuing a warning if there are one or more obstructions in the taxi path based on the LUT or else refraining from issuing a warning if there are not one or more obstructions in the taxi path based on the LUT. Converting audio to text can include using a machine learning model. Before converting the audio to text, the method can include checking communications between a pilot and air traffic control (ATC) for keywords relevant to taxiing. Converting audio to text can be performed upon detecting the keywords in the audio. The audio can include words spoken by ATC to the pilot and/or words spoken by the pilot to ATC.
