Solution Overview

Problem

Current flight management systems do not effectively adjust pilot workload during flights, leading to increased stress and workload peaks, which can impact safety and operational efficiency.

Innovation Solution

A method that uses a pilot tracking system to monitor workload and stress levels through sensors and biometric data, allowing for real-time adjustments during flights and predictive adjustments before flights by shifting tasks and optimizing crew rosters based on historical data analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If flight management systems generate detailed flight plans with multiple waypoints and parameters, then flight control precision is improved, but pilot workload increases

Engineering Contradiction:
Improveflight control precisionVSAvoidpilot workload
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The FMS automatically generates flight plans, calculates waypoints, and manages flight parameters without requiring manual pilot input for each parameter, allowing the system to serve itself in planning while pilots focus on execution and monitoring

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The FMS pre-calculates and stores optimal flight paths, waypoints, and parameters before the flight begins, so that during the actual flight, pilots only need to follow pre-prepared instructions rather than calculating everything in real-time

Inventive Principle:
Principle #10Preliminary action

2Productivity

If FMS automatically generates flight plans considering multiple parameters, then flight efficiency is improved, but pilot task load increases

Engineering Contradiction:
Improveflight efficiencyVSAvoidpilot task load
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system divides flight management into distinct segments: automated planning functions (route generation, parameter calculation) handled by FMS and manual execution/monitoring functions handled by pilots, allowing each to operate within their optimal capacity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The FMS acts as an intermediary between flight planning requirements and pilot execution, translating complex operational needs into simplified pilot instructions and alerts while handling the computational complexity itself

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If pilots manage complex flight plans with multiple constraints, then flight safety is improved, but stress levels increase

Engineering Contradiction:
Improveflight safetyVSAvoidpilot stress
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The FMS continuously monitors flight progress, compares actual position with planned path, and provides real-time feedback to pilots through alerts and notifications, reducing the cognitive burden of constant self-monitoring and lowering stress while maintaining safety

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-monitoring of flight parameters, automatic deviation detection, and constraint verification, freeing pilots from the stress of managing all safety-critical parameters simultaneously while maintaining high safety standards

Inventive Principle:
Principle #25Self-service

AI summary

A method (140) of adjusting (143) an operator workload during a travel segment including tracking (141) over a time period, using at least one sensor (103, 105, 106, 112, 117), one of inputs by an operator indicative of an operator workload or image sensor data or a biometric parameter indicative of an operator stress level during the travel segment. Determining (142), using a controller (120) that is operatively connected to the at least one sensor (103, 105, 106, 112, 117), a level of one of the operator workload or operator stress level. The method (140) also includes adjusting (143), using a controller (120) that is operatively connected to the control computer (22), the operator workload when the level of one of the operator workload or operator stress level exceeds a predetermined threshold.
