Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft fuel management systems face challenges in reducing fuel reserves while maintaining flight safety, as existing methods do not effectively account for unforeseen flight conditions, leading to increased fuel consumption and weight.
Innovation Solution
A fuel management system that compares theoretical and actual fuel consumption values during flight, initiating measures such as reducing flight speed or adjusting on-board energy consumption to optimize fuel use, allowing for a reduction in reserve fuel without compromising safety.

Engineering Contradiction Analysis
1Weight of moving object
If the quantity of reserve fuel carried on board is reduced to lower the aircraft weight, then fuel consumption and operating costs are reduced, but flight safety may be compromised due to insufficient fuel reserves for unforeseen events
Solution Approach 1:
The fuel management system continuously monitors actual fuel consumption and compares it with planned consumption, providing feedback to the flight crew when deviations exceed thresholds. This real-time feedback enables dynamic adjustment of fuel reserves based on actual flight conditions rather than static pre-flight calculations, allowing reduced reserve fuel while maintaining safety through active monitoring and intervention capabilities
Solution Approach 2:
The system transitions from static fuel reserve calculations to dynamic fuel management by continuously adapting fuel consumption assessments to actual flight conditions. The fuel reserve requirement changes dynamically based on real-time monitoring of consumption patterns, enabling the system to optimize the balance between weight reduction and safety margins throughout the flight
2Device complexity
If traditional fuel management methods are used without real-time monitoring, then system complexity is reduced, but fuel consumption increases due to inability to detect and respond to deviations from planned consumption
Solution Approach 1:
The system implements continuous feedback loops that monitor actual fuel consumption against planned consumption, automatically detecting deviations and triggering alerts or automated responses. This feedback mechanism enables the system to respond dynamically to changing flight conditions, optimizing fuel usage without requiring overly complex manual intervention procedures
Solution Approach 2:
The fuel management system performs self-monitoring and self-assessment of fuel consumption patterns, automatically comparing actual consumption with planned consumption and initiating appropriate responses without requiring constant pilot intervention. This self-service capability reduces the operational burden on the flight crew while maintaining effective fuel management

AI summary
A computer implemented fuel management method and system for monitoring and minimizing a fuel consumption of an aircraft. The fuel management system and method determines, on the basis of model assumptions, a theoretical value relating to the quantity of fuel that is necessary for travelling along at least one sector of a flight route. Furthermore, the fuel management system and method determine a practical value relating to a quantity of fuel that is necessary for travelling along the same sector of the flight route, taking into account actual measured values. Moreover, the system and method compare the theoretical value with the practical value and to provide at least one measure in order to save fuel during a flight when the practical value differs from the theoretical value by a predeterminable amount.
