Aircraft Landing Gear Controller Failure Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft landing gear control systems require significant pilot intervention and time to troubleshoot failures during take-off and landing, increasing workload and potentially delaying operations when landing gear systems malfunction.
Innovation Solution
An aircraft landing gear control system with a controller that autonomously determines failure reasons through sensor data analysis and initiates remedial actions, such as changing operation procedures or executing maneuvers, to quickly address landing gear system malfunctions, reducing the need for flight crew intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional landing gear control systems are used, then the system structure is simple, but pilot workload increases and response time delays when failures occur
Solution Approach 1:
The controller automatically detects landing gear failures, diagnoses the cause, and executes remedial actions without pilot intervention. The system monitors sensor data, compares it against expected parameters, and autonomously determines whether to retract, extend, or hold the landing gear based on the detected failure mode, enabling the system to service itself during critical operations.
Solution Approach 2:
The system continuously monitors landing gear operation through multiple sensors and provides feedback to the controller. When a failure is detected, the controller uses this feedback to diagnose the problem and adjust the landing gear operation accordingly, creating a closed-loop control system that responds dynamically to actual system conditions.
2Loss of time
If manual troubleshooting procedures are used, then the control system remains simple, but operation time increases during failure conditions
Solution Approach 1:
The controller is pre-programmed with multiple failure scenarios and corresponding remedial actions. When a failure occurs, the system immediately matches the detected condition against stored failure modes and executes the predetermined appropriate action, eliminating the need for pilots to manually diagnose and decide on corrective measures during high-stress situations.
Solution Approach 2:
The system autonomously performs the troubleshooting and corrective actions that would traditionally require pilot intervention. The controller monitors system parameters, identifies failures, and executes remedial procedures without requiring the flight crew to manually troubleshoot, thereby reducing both the time lost and the operational burden on pilots.
3Reliability
If automated failure detection and remedial actions are implemented, then response time decreases, but system complexity increases
Solution Approach 1:
The controller automatically detects landing gear failures, diagnoses the cause, and executes remedial actions without pilot intervention. The system monitors sensor data, compares it against expected parameters, and autonomously determines whether to retract, extend, or hold the landing gear based on the detected failure mode, enabling the system to service itself during critical operations.
Solution Approach 2:
The controller serves multiple functions: normal landing gear control, failure detection, failure diagnosis, and automated remedial action execution. By consolidating these diverse functions into a single control unit, the system achieves high reliability without proportionally increasing overall system complexity.

AI summary
Disclosed is an aircraft landing gear control system (1000) configured to be operably connected to one or more landing gear systems (30, 40) of an aircraft. The aircraft landing gear control system comprises a controller (20) that is configured, in use, to: send at least one output for initiating operation of the one or more landing gear systems; determine whether at least one landing gear system of the one or more landing gear systems has failed to operate correctly in response to the at least one output; and determine at least one remedial action to be taken, when the controller determines that the at least one landing gear system has failed to operate correctly.
