Aircraft Maintenance Information Management via Impact Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft maintenance systems do not effectively manage breakdowns that have economic impacts, such as delays and passenger discomfort, as these issues are not prioritized or reported, leading to inefficiencies and increased costs.
Innovation Solution
A method for managing maintenance information items that determines the economic impact of breakdowns using an impact attribute, allowing for prioritization and real-time processing of messages, enabling airlines to address significant economic impacts without disturbing pilots and optimizing maintenance operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If maintenance messages are transmitted in real time during flight, then the volume and cost of transmissions increase, but safety-critical problems can be addressed promptly
Solution Approach 1:
The patent applies local quality by assigning different transmission priorities to different types of maintenance messages. Safety-critical messages are transmitted in real-time during flight, while non-critical economic impact messages are deferred to ground-based processing. This selective approach ensures that only essential transmissions consume in-flight communication resources, resolving the contradiction between reliable safety monitoring and transmission cost control.
2Ease of operation
If all maintenance messages are processed during stopovers, then maintenance operations are simplified, but aircraft delays increase due to inability to prioritize critical issues
Solution Approach 1:
The patent implements preliminary action by pre-classifying maintenance messages into different priority categories (safety-critical and economic impact) before stopover processing. This classification enables the maintenance team to immediately identify and address critical issues during stopovers, while non-urgent economic impact messages can be handled subsequently. This resolves the contradiction by maintaining operational simplicity while preventing delays through advance prioritization.
3Loss of information
If pilots are notified of all breakdowns via cockpit warning system, then complete information is provided to maintenance team, but pilot workload increases and safety-critical warnings are diluted
Solution Approach 1:
The patent applies segmentation by dividing maintenance information into distinct categories: safety-critical breakdowns are communicated to pilots through the cockpit warning system, while economic impact breakdowns are handled separately through ground-based maintenance message processing. This segmentation ensures pilots receive only essential safety information, maintaining ease of operation, while complete maintenance information is preserved through separate processing channels.
4Reliability
If maintenance team responds to all logbook entries exhaustively, then all breakdowns are addressed, but processing time increases and efficiency decreases
Solution Approach 1:
The patent implements partial action by requiring exhaustive processing only for safety-critical logbook entries, while economic impact messages receive prioritized but not necessarily exhaustive processing. This approach maintains reliability for critical safety issues while improving overall maintenance efficiency by applying differentiated processing intensity based on message priority and impact level.
Data Source
AI summary
A method and a device for management of maintenance information items in an aircraft comprising a centralized maintenance system is disclosed. After a maintenance message has been received, the value of an impact attribute associated with the message received is determined according to predetermined configuration data. In response to the message received and to the value of the impact attribute associated with the at least one message received, the message received is processed. A determination of configuration data for the management of maintenance information items in an aircraft is also explained.
