Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft avionics systems face challenges in promptly reporting faults to maintenance personnel, leading to delayed corrective actions, as information is not communicated expeditiously enough for efficient investigation and solution implementation.
Innovation Solution
An Electronic Flight Bag (EFB) system is used to communicate with a remote aircraft system data communications unit, receiving and identifying aircraft systems data, automatically reporting problems, receiving solutions, and implementing fixes, thereby facilitating real-time diagnostics and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual fault reporting by aircraft crew is used, then maintenance personnel can eventually receive fault information, but the reporting process is delayed and not expeditious enough for efficient investigation and corrective action
Solution Approach 1:
The aircraft systems automatically perform fault detection and reporting without requiring manual intervention from the aircraft crew. The system self-monitors its own status and autonomously transmits fault information to maintenance personnel, eliminating the delay associated with manual fault reporting while maintaining high maintenance efficiency
Solution Approach 2:
The system establishes a continuous feedback loop where fault information is automatically detected by aircraft systems and immediately transmitted to maintenance personnel. This real-time feedback mechanism ensures that maintenance teams receive expeditious notification of faults, enabling prompt investigation and corrective action, thus reducing both reporting time and improving maintenance productivity
2Productivity
If remote diagnostic capabilities are implemented, then maintenance efficiency and aircraft availability are enhanced, but system complexity increases
Solution Approach 1:
The Electronic Flight Bag (EFB) is utilized as a multi-functional device that serves both as a standard flight information system and as a remote diagnostic communication terminal. By leveraging the existing EFB infrastructure for dual purposes, the system achieves enhanced maintenance efficiency through remote diagnostics without proportionally increasing overall system complexity
Solution Approach 2:
The system employs an intermediary communication architecture where the EFB acts as a mediator between aircraft systems and remote maintenance personnel. This intermediary approach enables remote diagnostic capabilities by facilitating data transmission through an existing communication channel, thereby improving maintenance efficiency while minimizing the increase in system complexity
