Aircraft Navigation Instrument Testing With Automated Error Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft navigation instrument testing systems are prone to human errors due to the need for manual reference to manufacturer specifications and charts, leading to potential inaccuracies in determining whether the instruments are within acceptable error margins.
Innovation Solution
A system comprising a test device connected to sensors, a wireless device with a human-machine interface and image acquisition means, and a database with predetermined values and error margins, allowing automated comparison and validation of instrument readings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual reference to manufacturer specifications and charts is used for testing navigation instruments, then the operator can verify instrument values, but human errors occur leading to potential inaccuracies in determining whether instruments are within acceptable error margins
Solution Approach 1:
The patent creates a digital copy of the manufacturer's specifications and charts in the form of a database stored in the wireless device. This digital copy contains predetermined values and acceptable error margins for various navigation instruments, allowing the system to automatically reference accurate specifications without relying on manual interpretation of physical documents or charts.
Solution Approach 2:
The patent replaces the manual mechanical process of referring to physical specifications and charts with an automated electronic system. The wireless device automatically retrieves predetermined values from the database, compares them with instrument readings, and determines compliance without human intervention in the measurement and comparison process.
2Productivity
If the operator manually compares instrument values with predetermined values and error margins, then the testing process can be performed, but the process is time-consuming and prone to errors
Solution Approach 1:
The wireless device performs self-service by automatically retrieving predetermined values from its internal database, comparing them with instrument readings, and determining compliance status without requiring the operator to manually perform these tasks. The system serves itself by autonomously completing the comparison and verification process.
Solution Approach 2:
The system provides immediate feedback by automatically comparing instrument readings with stored predetermined values and displaying the compliance status. This automated feedback loop eliminates the time-consuming manual comparison process and provides instant results to the operator.
3Adaptability or versatility
If the operator refers to manufacturer manuals and charts for each aircraft model, then the correct specifications can be found, but the complexity of the testing process increases due to the need to consult multiple documents
Solution Approach 1:
The wireless device is designed with universal functionality by incorporating a comprehensive database that stores specifications for multiple aircraft models and navigation instrument types. This single device can handle various aircraft models without requiring the operator to switch between different manuals or documents, as all necessary specifications are available within the unified system.
Solution Approach 2:
The patent merges the functionality of multiple manufacturer manuals, charts, and specification documents into a single integrated database within the wireless device. This consolidation combines what would otherwise be separate external references into one unified resource, simplifying the testing process while maintaining adaptability to different aircraft models.
