Aircraft Piloting Display Window Positioning for Stable Flight Path Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current piloting assistance methods for aircraft, particularly in the military domain, are inadequate as they fail to provide a stable and continuous display of the aircraft's position and flight path during transitional phases, such as between climbs and descents, leading to difficulties in monitoring the upcoming path and potential disorientation for pilots.
Innovation Solution
The method involves determining the current flight phase and altitudes to adjust the positioning of the display window and the aircraft symbol on a vertical plane representation, ensuring the lowest point of the vertical section is always visible on the y-axis, maintaining continuous transitions and optimal path monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the usual information presentation is used for tactical flights, then the display shows the vertical plane along the flight path, but the position of the display window and aircraft symbol jumps during transitions between flight phases
Solution Approach 1:
The patent applies dynamics by making the reference altitude adaptive rather than fixed. The reference altitude automatically adjusts based on the current flight phase and the altitude of the aircraft, ensuring that the display window and aircraft symbol maintain stable positions during transitions between different flight phases (climb, cruise, descent). This dynamic adjustment prevents the jumping effect observed in static display systems.
Solution Approach 2:
The patent changes the parameter of reference altitude from a fixed value to a variable that depends on flight phase and aircraft altitude. By modifying this key parameter dynamically, the system maintains continuous and stable visual representation of the aircraft position and flight path across all flight phases, eliminating the discontinuities that occur with fixed reference systems.
2Device complexity
If the aircraft symbol position is based on selected or destination altitude, then the display is simple, but it is difficult to monitor the future path during tactical flights with multiple altitude changes
Solution Approach 1:
The patent segments the flight path into different phases (climb, cruise, descent, low-altitude flight) and applies specific positioning logic to each phase. This segmentation allows the system to maintain simplicity within each phase while providing comprehensive visibility of the upcoming path across all phases, as each phase has its own optimized reference altitude calculation.
Solution Approach 2:
The patent adds the dimension of flight phase awareness to the altitude-based positioning system. By incorporating flight phase information into the reference altitude calculation, the system moves beyond simple altitude-based positioning to a more sophisticated two-dimensional approach (altitude + flight phase) that maintains both simplicity and comprehensive path visibility.
3Ease of manufacture
If the display window and aircraft symbol positions are fixed, then the system is simple to implement, but positional jumps occur during transitions between climb and descent phases
Solution Approach 1:
The patent transforms the static positioning system into a dynamic one by making the reference altitude dependent on the current flight phase and aircraft altitude. This dynamic approach maintains ease of implementation through automated calculations while ensuring continuous and stable display composition during transitions between climb and descent phases.

AI summary
A device to assist in the piloting of an aircraft includes a display unit to present, in a display window of a screen, an information presentation illustrating a vertical plane along a flight path which represents a flight plan and which is formed so as to position the display window altitude-wise, and to further position a symbol illustrating the aircraft vertically in the display window, where the positioning of the display window and the symbol are based on the current flight phase, the current altitude and an altitude relative to the flight path.
