Travel Path Deviation Detection for Aircraft Crew Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft systems lack the capability to provide real-time awareness and assistance to flight crews regarding deviations from preprogrammed travel plans, which can lead to potential safety issues due to pilot distraction or system errors.
Innovation Solution
A system that includes a database to store a preprogrammed travel plan, a navigation system to monitor the aircraft's position, and a controller to detect deviations from the plan, generating notifications to the crew when specific parameters exceed thresholds, such as time or distance from the planned route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing aircraft systems (TCAS, TAWS, pilot state monitoring) are implemented, then overall safety is improved, but specific task awareness and assistance are not provided
Solution Approach 1:
The system segments the monitoring function into specific task-oriented components. Instead of general safety monitoring, the system divides functionality into: (1) flight plan deviation detection, (2) parameter threshold monitoring, and (3) targeted crew notification. This segmentation allows the system to provide specific task awareness while maintaining overall safety.
Solution Approach 2:
The system implements feedback by continuously monitoring flight parameters and providing real-time notifications to the flight crew when deviations occur. The controller receives data from the flight management system, compares actual parameters against thresholds, and feeds back alerts to the crew, creating a closed-loop information system that addresses specific task awareness.
2Measurement precision
If continuous monitoring of flight parameters is implemented, then deviation detection capability is improved, but system complexity increases
Solution Approach 1:
The system achieves multi-functionality by using a single controller that performs multiple roles: (1) receiving flight data from the flight management system, (2) comparing parameters against stored thresholds, (3) determining deviations, and (4) generating notifications. This universal approach improves deviation detection without proportionally increasing system complexity, as one component handles multiple functions.
Solution Approach 2:
The system employs self-service by automatically monitoring its own operational parameters and making decisions about when notifications are needed. The controller autonomously compares flight data against thresholds and determines when deviations occur, eliminating the need for manual monitoring and reducing overall system complexity while maintaining high measurement precision.
3Loss of information
If real-time parameter monitoring and notification systems are implemented, then flight crew awareness is improved, but loss of time for processing and responding increases
Solution Approach 1:
The system applies preliminary action by pre-establishing threshold values for critical flight parameters during system configuration. These thresholds are set in advance based on operational requirements and safety criteria. When flight parameters reach these pre-defined thresholds, the system immediately triggers notifications, eliminating the need for real-time analysis decisions and reducing response time while maintaining high crew awareness.
