Aircraft Flight Profile Display Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flight profile display systems suffer from low readability of vertical profiles due to automatic adjustment of the vertical scale resolution, which becomes less legible at higher altitudes, preventing the observation of certain details.
Innovation Solution
A method and electronic device that compute a reference altitude and range of altitudes for the vertical flight profile, adapting to the current altitude and estimated altitude evolution, allowing for dynamic adjustment of the displayed range based on the selected display mode (tracking or flight plan) to enhance readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vertical scale resolution is automatically adjusted to vary inversely with the maximum altitude, then the display can accommodate higher altitudes, but the resolution becomes lower and the vertical profile becomes less legible
Solution Approach 1:
The patent applies dynamics by making the reference altitude movable and adjustable rather than fixed. The reference altitude can be dynamically modified based on flight parameters such as current altitude, vertical speed, and flight phase, allowing the display to adapt to different flight conditions while maintaining optimal readability of the vertical profile
Solution Approach 2:
The patent changes the parameter of reference altitude from a static value to a dynamically adjustable parameter. By modifying the reference altitude based on flight conditions (climb, descent, level flight), the system maintains appropriate vertical scale resolution across different altitude ranges, preventing the resolution degradation that occurs with automatic inverse adjustment
2Ease of operation
If the reference altitude is fixed according to standard barometric altitudes, then the display system is simple to operate, but it cannot adapt to different flight conditions and estimated altitude evolution
Solution Approach 1:
The system performs self-service by automatically computing and adjusting the reference altitude based on flight parameters without requiring manual intervention from the pilot. The electronic display management device continuously monitors flight conditions and dynamically modifies the reference altitude to optimize the vertical profile display for current flight phases
Solution Approach 2:
The patent implements feedback by using flight parameters (current altitude, vertical speed, flight phase) to continuously adjust the reference altitude. This closed-loop approach ensures the display adapts to changing flight conditions, providing appropriate vertical scale resolution for climb, descent, and level flight phases

AI summary
This method for managing the display of a flight profile of an aircraft is implemented by an electronic management device.It comprises computing a reference altitude for the display of a vertical flight profile; determining a range of altitudes for the display of said vertical profile, the range of altitudes being determined as a function of the computed reference altitude, the reference altitude being computed as a function of a current altitude, an altitude interval to be displayed and at least one property relative to an estimated evolution of the altitude of the aircraft from said current altitude.
