Solution Overview

Problem

Current aircraft systems are not designed to support a single pilot effectively, leading to increased stress and burden due to the concentration of flight responsibilities on one person, lacking the redundancy provided by a two-pilot crew.

Innovation Solution

A pilot notification system utilizing artificial intelligence to analyze the pilot's cognitive state, workload, and flight conditions, adjusting communication methods to accommodate these factors, similar to a co-pilot, by modifying a large language model (LLM) to provide tailored alerts and messages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single pilot operates the aircraft without redundancy, then crew size and training costs are reduced, but pilot stress and workload increase significantly

Engineering Contradiction:
Improvecrew efficiencyVSAvoidpilot stress
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an AI notification system as an intermediary between flight systems and the single pilot. This mediator processes flight data, monitors pilot cognitive state, and delivers tailored notifications, effectively sharing the mental burden and reducing pilot stress while maintaining single-pilot operation efficiency

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system continuously monitors pilot cognitive state through sensors and uses this feedback to dynamically adjust notification strategies. When pilot stress or cognitive load is detected, the system modifies alert delivery to prevent overload, creating a closed-loop feedback mechanism that maintains optimal pilot performance

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If flight responsibilities are concentrated on one pilot, then crew resource utilization is improved, but the loss of redundancy increases safety risks

Engineering Contradiction:
Improvecrew resource utilizationVSAvoidsafety redundancy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The AI notification system performs self-monitoring of flight conditions and pilot state, automatically detecting when interventions are needed without requiring a second pilot. The system serves itself by autonomously managing notification delivery based on real-time assessments of flight criticality and pilot capacity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical redundancy of a second pilot with an electronic/AI-based notification system that provides similar safety functions through automated monitoring, alert optimization, and cognitive state management

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If traditional notification systems are used without adaptation, then system complexity is minimized, but communication effectiveness with the pilot deteriorates under stress

Engineering Contradiction:
Improvenotification system complexityVSAvoidcommunication effectiveness
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The notification system dynamically adapts its behavior based on real-time pilot cognitive state and flight conditions. Alert timing, modality, and content are adjusted dynamically to match pilot capacity and situation criticality, transforming a static notification system into a dynamic, context-aware communication interface

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes multiple parameters including notification timing, delivery modality (visual/auditory), information detail level, and alert priority based on pilot cognitive state measurements and flight condition assessments, optimizing communication effectiveness across varying operational contexts

Inventive Principle:
Principle #35Parameter changes

AI summary

A pilot notification system includes multiple sensors, multiple modules, and a large language model (LLM (110)). The modules processes inputs to determine the cognitive state of the pilot, the current pilot workload, and the current flight conditions of the aircraft. These modules send this information to other modules which process this information and send the information to the LLM (110). The structure of the LLM (110) is modified to reflect the pilot's current cognitive state, the pilot's current workload, and the current flight conditions. The LLM (110) generates a pilot alert message to alert the pilot of import information while considering the current circumstances.
