Aircraft Takeoff Configuration Alerting System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft take-off warning systems fail to specifically identify which control surfaces are incorrectly configured, leading to unclear warnings for crew members during take-off, potentially causing incidents and accidents.
Innovation Solution
A system that includes a processor, user input for desired control-surface configuration, a control-surface sensor to provide current configuration, and aircraft position data to generate alarms and visual displays indicating specific control surfaces requiring adjustment before take-off, ensuring accurate identification of configuration discrepancies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a general take-off configuration warning horn is used, then the system is simple and provides basic warning functionality, but it fails to identify which specific control surfaces are incorrectly configured, leading to unclear warnings for crew members
Solution Approach 1:
The patent divides the control surface monitoring into discrete segments by providing individual sensors for each control surface (flaps, spoilers, trim). Each sensor independently monitors its specific control surface and provides distinct signals to the processor, enabling identification of which specific surface is misconfigured rather than providing a general warning only.
2Measurement precision
If individual sensors are installed for each control surface to identify misconfigurations, then specific control surface identification is achieved, but the device complexity and cost increase
Solution Approach 1:
The patent employs a single multi-functional processor that handles multiple tasks: receiving signals from multiple different control surface sensors, comparing configurations against the flight management system, determining aircraft position, and generating warnings. This centralized processing approach allows one component to perform what would otherwise require multiple specialized components.
Solution Approach 2:
The patent combines the take-off configuration warning system with the existing flight management system and aircraft position determination systems. The processor utilizes already-available aircraft position data and integrates control surface monitoring into the existing operational framework, reducing the need for completely separate systems.
3Ease of operation
If the warning system only provides general alerts without specific configuration details, then the system is easy to operate, but crew members cannot quickly identify and correct the specific problem during take-off preparation
Solution Approach 1:
The patent implements a feedback mechanism where the processor continuously compares actual control surface configurations (from sensors) against desired configurations (from the flight management system). When a discrepancy is detected, the system provides immediate feedback to the crew through distinct warnings that identify the specific misconfigured surface, enabling rapid correction before take-off.

AI summary
A system implementable in an aircraft for generating a warning includes a processor (36), a first component (35) configured to receive from a user a desired aircraft control-surface takeoff configuration, a second component (32) configured to provide to the processor a first signal indicative of a current control-surface configuration of the aircraft, and a third component (30) configured to provide to the processor a second signal indicative of the position of the aircraft. The processor may be configured to compare the aircraft position to the contents of a database (39), determine, based on the comparison, whether the aircraft is on a departure runway from which the aircraft is to depart, and generate an alarm if the aircraft is on the departure runway and the current control-surface configuration is different from the desired control-surface takeoff configuration.
