Aircraft Incapacity Detection and Autopilot Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircrafts face challenges in maintaining safe operation when flight crews become incapacitated due to hypoxia or unauthorized control, leading to potential unsafe flight paths and loss of control, which existing systems fail to address effectively.
Innovation Solution
An on-board system that automatically takes control of the aircraft by detecting absence of heuristic human behavior, requesting crew acknowledgment, and engaging autopilot if necessary, while transmitting alerts and attempting to descend to safe altitudes or redirecting the aircraft to safe areas to prevent collateral damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flight crew becomes incapacitated due to hypoxia or unauthorized control, then the aircraft operation safety deteriorates, but existing systems lack the capability to automatically take control and redirect the aircraft to safe areas
Solution Approach 1:
The system performs preliminary actions by monitoring crew status continuously and preparing automated control protocols in advance. When incapacity is detected, the system has pre-programmed sequences to engage autopilot, request acknowledgment, and redirect to safe areas without requiring real-time human decision-making during the critical response phase.
Solution Approach 2:
The aircraft system serves itself by automatically detecting crew incapacity through sensor data analysis, autonomously engaging the autopilot system, and executing pre-planned redirection to safe areas. The system uses its own onboard sensors, processors, and control mechanisms to maintain safety without external intervention.
2Reliability
If the system automatically takes control of the aircraft upon detecting crew incapacity, then the aircraft can be redirected to safe areas, but the complexity of the control system increases
Solution Approach 1:
The existing autopilot and flight management systems are extended to perform multiple functions: normal flight control, crew status monitoring, incapacity detection, automated acknowledgment requests, and emergency redirection. This multi-functionality reduces the need for entirely separate emergency control systems.
Solution Approach 2:
The system continuously monitors crew status through sensors and feedback loops, comparing data against incapacity thresholds. When incapacity is detected, the system provides feedback by engaging the autopilot and executing pre-programmed redirection sequences, creating a closed-loop control system that adapts to the detected condition.
3Reliability
If the system monitors crew status continuously to detect incapacity, then early intervention is possible, but the energy consumption and system resource usage increase
Solution Approach 1:
Instead of continuous monitoring, the system periodically samples crew status data at predetermined intervals. This periodic action reduces energy consumption and processing requirements while still providing timely detection of incapacity conditions, balancing monitoring effectiveness with resource conservation.

AI summary
A method for automatic control of an aircraft in event of flight crew incapacity may include determining any incapacity of the flight crew. The method may also include providing a message requiring acknowledgement from the flight crew in response determining incapacity of the flight crew. The method may additionally include commanding an auto pilot to control the aircraft in response to not receiving acknowledgement from the flight crew.
