Aircraft Landing Alert Control Using Port Weather Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft alert systems cannot effectively control the behavior of alerts based on weather conditions at the scheduled landing location, leading to insufficient alerts in varying weather conditions.
Innovation Solution
A control device that acquires weather information related to the scheduled landing location and adjusts the alert behavior of an alerter accordingly, ensuring a sufficient alert is performed based on the weather conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed alert behavior is used regardless of weather conditions, then the device complexity is reduced and ease of operation is improved, but the reliability of the alert system deteriorates because the alert may not be sufficient in varying weather conditions
Solution Approach 1:
The patent applies parameter changes by adjusting alert behavior parameters (such as alert duration, intensity, or repetition) based on weather condition parameters. The control device receives weather information and modifies the alert output parameters accordingly, allowing the same alert device to adapt its behavior to different weather conditions without requiring fundamentally different systems.
Solution Approach 2:
The patent implements feedback by continuously monitoring weather conditions and using this information to adjust alert behavior in real-time. The control device receives weather data, processes it according to predetermined rules, and dynamically modifies the alert output, creating a closed-loop system that responds to environmental changes.
2Reliability
If weather information is acquired and processed to adjust alert behavior, then the reliability of the alert system is improved, but the device complexity increases due to additional acquisition and control components
Solution Approach 1:
The control device performs multiple functions: it receives weather information, processes the information according to predetermined criteria, and controls the alert device behavior. By consolidating these functions into a single control unit, the patent reduces overall system complexity while maintaining the ability to adapt alert behavior to weather conditions.
3Adaptability or versatility
If the alert behavior is dynamically adjusted based on weather conditions, then the adaptability of the alert system is improved, but the difficulty of detecting and measuring weather parameters increases the system complexity
Solution Approach 1:
The patent uses an intermediary approach by receiving weather information from external sources (such as weather stations or meteorological services) rather than directly measuring all weather parameters itself. This allows the alert system to adapt to weather conditions without requiring complex onboard weather detection equipment.

AI summary
A control device (900) includes an acquirer (910) that acquires information expressing weather related to a port that is a location at which a landing of an aircraft is scheduled, and a controller (930) that causes an alerter to perform a behavior corresponding to the weather expressed in the acquired information. The alerter performs an alert related to the landing of the aircraft.
