Aircraft Data Backup System Using Stable Flight Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data backup methods for aircraft systems require grounding, leading to increased operational costs and potential disruptions in aircraft systems, as they prioritize backup over other functions during stable flight conditions.
Innovation Solution
A backup system that utilizes flight information to predict stable flight periods, allowing data to be backed up during low system load times using a first and second storage configuration, with a detector providing altitude, position, speed, and weather data, and a controller initiating the backup process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data backup is performed on the ground with highest priority, then data protection reliability is improved, but aircraft system availability deteriorates and maintenance efficiency worsens
Solution Approach 1:
The backup system dynamically adjusts its operation based on flight conditions. The controller monitors flight state information and automatically activates backup operations only during stable flight phases, while disabling them during unstable phases. This dynamic adaptation allows the system to maintain data protection reliability when conditions permit, while avoiding disruptions to aircraft systems and maintenance operations when conditions do not permit.
Solution Approach 2:
The system changes the operational parameter of the backup function based on flight stability parameters. When flight stability exceeds a predetermined threshold, the backup function is activated with high priority. When stability falls below the threshold, the backup function is deactivated or lowered in priority. This parameter-based control resolves the contradiction by making backup reliability contingent on favorable flight conditions.
2Reliability
If data backup is performed on the ground, then data protection is improved, but aircraft operational cost increases due to extended parking time
Solution Approach 1:
The backup system performs data backup operations preliminarily during stable flight phases before the aircraft lands. By completing backup tasks during the flight itself, the system eliminates or reduces the need for ground-based backup operations, thereby reducing aircraft parking time and associated operational costs while maintaining data protection reliability.
Solution Approach 2:
The system continues useful backup actions during stable flight periods rather than interrupting flight for ground-based backup. This continuous operation during flight time eliminates the need to park the aircraft for maintenance-related backup tasks, reducing time loss and operational costs while maintaining data protection.
3Speed
If backup process is given highest priority during stable flight, then backup speed is improved, but aircraft system availability deteriorates
Solution Approach 1:
The system dynamically controls backup priority based on flight stability. During stable flight, the backup process is given high priority to execute quickly. During unstable flight, backup priority is reduced or suspended to maintain aircraft system availability. This dynamic priority adjustment resolves the contradiction by making backup speed contingent on favorable flight conditions.
Solution Approach 2:
The system takes preliminary action to prevent conflicts between backup operations and aircraft system availability by monitoring flight stability in advance. When instability is detected, the system proactively reduces backup priority before conflicts arise, thereby maintaining aircraft system availability while still enabling fast backup when conditions are favorable.

AI summary
A backup system (100) installed in an airplane comprises a controller (130), storages (140, 150), a detector (120), and an input apparatus (180). The first storage (140) stores a large amount of data needing to be backed up, such as software for on-board equipment and usage information for an entertainment apparatus (160) and a payment apparatus (170). Based on information from the detector (120) and the input apparatus (180), the controller (130) determines/predicts a transition to stable flight and determines a timing at which a backup operation will be carried out. In addition, an interruption of stable flight is predicted/determined and a backup process is interrupted. A priority is decided for each piece of data to be backed up, and a backup order is decided based on the priority. The backup system (100) predicts sections in which stable flight will be possible from meteorological information, etc., and performs backup.
