Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auto-flight systems and flight management systems are complex, leading to unintended mode activations, pilot confusion, and safety concerns due to non-intuitive interfaces and rigid control modes, which increase pilot workload and reduce flexibility in flight operations.
Innovation Solution
A touchscreen flight mode control panel that simplifies flight operations by reducing the number of auto-flight modes, integrating mode feedback and flight management information, and providing contextually sensitive displays to align with pilot goals, allowing for variable control and graphical demonstration of automation effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional flight control panels with multiple flight modes are used, then comprehensive flight control capability is achieved, but device complexity and difficulty of operation increase significantly
Solution Approach 1:
The touchscreen display integrates multiple flight control functions into a single universal interface. The system provides speed control, vertical navigation, and lateral navigation modes through one touchscreen panel, eliminating the need for separate physical control panels for each function. This multi-functional integration reduces the number of discrete components while maintaining comprehensive flight control capability.
Solution Approach 2:
The patent replaces traditional mechanical flight control panels with a touchscreen-based graphical user interface. Instead of physical buttons, switches, and displays for each flight mode, the system uses a touchscreen display with graphical representations that can be manipulated through touch gestures. This substitution eliminates mechanical complexity while preserving full flight control functionality.
2Adaptability or versatility
If comprehensive flight mode options are provided, then flight control versatility is improved, but ease of operation deteriorates due to pilot confusion and training requirements
Solution Approach 1:
The touchscreen display uses color-coded visual indicators to represent different flight modes and their status. Graphical elements change color or appearance to indicate active modes, armed modes, and system states, providing intuitive visual feedback that reduces pilot cognitive load. The color changes help pilots quickly understand system status without requiring extensive training on mode indicators.
Solution Approach 2:
The system provides continuous visual feedback through the touchscreen display that shows pilots what flight modes are active, what modes are armed, and what actions the system is about to take. This feedback mechanism reduces pilot confusion by making system intentions transparent, allowing pilots to understand automation effects without intensive training on complex mode logic.
3Productivity
If traditional flight management systems are used, then complete flight management functionality is achieved, but loss of information increases due to poor annunciation of flight modes
Solution Approach 1:
The patent adds a visual dimension to flight mode annunciation by displaying graphical representations on the touchscreen that show flight mode status, navigation intercepts, and automation effects. Instead of relying solely on text-based or auditory annunciation, the system uses visual graphics to convey system state and intentions, reducing information loss and improving pilot awareness of flight mode changes.
4Ease of operation
If rigid all-or-none pilot modes are enforced, then system control simplicity is maintained, but adaptability to specific flight circumstances is reduced
Solution Approach 1:
The system dynamically adjusts control modes based on flight conditions and pilot inputs through the touchscreen interface. Rather than enforcing rigid all-or-none modes, the system allows pilots to select from multiple flight modes (speed control, vertical navigation, lateral navigation) and dynamically switch between them based on specific flight circumstances. The touchscreen interface enables flexible mode selection and adjustment without complicating the overall control scheme.
