Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft flight information display systems experience a harmful loss of reference for pilots during abrupt transitions between three-dimensional and two-dimensional perspectives, disrupting the pilot's situational awareness and decision-making process.
Innovation Solution
A system that generates and displays successive three-dimensional transition synthesis images, centered around an intermediate central point of interest, with varying observation distance and opening angle as functions of the transition moment, to smoothly transition between three-dimensional and two-dimensional perspectives, maintaining pilot reference and situational awareness.

Engineering Contradiction Analysis
1Speed
If abrupt transition between three-dimensional and two-dimensional perspectives is implemented, then switching speed between perspectives is improved, but pilot reference stability deteriorates causing harmful loss of reference
Solution Approach 1:
The system dynamically adjusts the perspective transition by progressively modifying the opening angle and observation distance parameters. Instead of abrupt switching, the transition is made dynamic and continuous, allowing the display to adapt smoothly between 3D and 2D perspectives while maintaining pilot reference stability throughout the transition process.
Solution Approach 2:
The invention resolves the contradiction by changing key display parameters (opening angle and observation distance) during the transition. By progressively adjusting these parameters from their initial values to final values, the system enables smooth perspective transitions that maintain reference stability while achieving the desired switching between 3D and 2D views.
2Stability of the object's composition
If three-dimensional synthesis images are displayed with fixed observation distance and opening angle, then image consistency is improved, but adaptability to different transition moments deteriorates
Solution Approach 1:
The system makes the observation distance and opening angle dynamic rather than fixed. These parameters are continuously adjusted as functions of the transition moment, allowing the image to adapt to different stages of the transition while maintaining overall consistency through controlled progression from initial to final parameter values.
Solution Approach 2:
The transition process is structured as a periodic sequence of parameter adjustments. The opening angle and observation distance are systematically modified at different transition moments, creating a structured progression that maintains image consistency while adapting to the specific requirements of each transition stage.
3Stability of the object's composition
If perspective transition is made smooth by progressive parameter adjustment, then pilot reference stability is improved, but transition time increases
Solution Approach 1:
The system optimizes the balance between stability and time by strategically changing parameters (opening angle and observation distance) as functions of the transition moment. This allows the transition to be smooth and stable while controlling the overall transition time through efficient parameter progression.

AI summary
A system for displaying information related to a flight of an aircraft and an associated method are provided. The display system comprises a dynamic synthesis image generating module, configured to generate at least two successive transition synthesis images between an image according to a first type of perspective and an image according to a second type of perspective, or between an image according to a second type of perspective and an image according to a first type of perspective, respectively, and to command the display thereof at successive transition moments. Each transition image is centered around an intermediate central point of interest, seen from an intermediate point of view situated at an intermediate observation distance from the intermediate central point of interest, which is an increasing function, a decreasing function, respectively, of the transition moment at which the image is displayed, and seen from an intermediate opening angle, which is a decreasing function, an increasing function, respectively, of the transition moment at which this image is displayed.
