Visual Flight Attitude Indicator Using Damped Earth Model
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern aircraft face safety risks when instrument failures occur, especially in low-visibility conditions, as pilots struggle to maintain control without reliable attitude indicators.
Innovation Solution
A visual model of flight attitude is introduced, comprising a cross-shaped LED lamp, a dome, a vertical tube, an earth model, and a laser pointer, which provides a reliable and independent means for pilots to determine the aircraft's attitude by mimicking the Earth's gravitational orientation, using a miniature dome with damping fluid and a diamagnetic earth model to eliminate external influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If pilots rely on advanced cockpit instruments for all-weather autopilot operation, then flight automation and operational capability are improved, but reliability deteriorates when instrument failures occur due to accidents or maintenance issues
Solution Approach 1:
The patent introduces a simple visual model as an intermediary device between the pilot and the aircraft attitude. This model provides a direct, intuitive visual representation of pitch and roll angles using mechanical indicators and colored zones, serving as a reliable backup when electronic instruments fail. The visual model acts as a mediator that translates complex instrument data into simple, easily interpretable visual cues.
Solution Approach 2:
The patent creates a simplified copy or replica of the aircraft's attitude information through a mechanical visual model. Instead of relying on complex electronic displays, the system creates a physical copy of the attitude data using moving indicators that replicate pitch and roll angles, making the information accessible even when electronic systems fail.
2Extent of automation
If pilots perform manual flight based on experience during instrument failure in low visibility, then automation dependency is reduced, but measurement precision of aircraft attitude deteriorates
Solution Approach 1:
The patent replaces reliance on pilot experience and memory with a mechanical visual indication system. The device uses mechanical linkages connected to the aircraft's actual attitude to drive visual indicators, providing objective, precise measurements of pitch and roll angles without requiring pilot interpretation or experience-based estimation.
Solution Approach 2:
The patent employs color-coded zones (green, yellow, red) on the visual model to indicate different attitude ranges. These color changes provide immediate, intuitive feedback about the aircraft's attitude status, allowing pilots to quickly assess whether the aircraft is within safe operating parameters without complex instrument interpretation.
3Device complexity
If a simple visual indicator model is installed in the cockpit, then device complexity is reduced and ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent divides the visual indication system into separate, modular components: pitch indication mechanisms, roll indication mechanisms, and reference markings. Each component can be calibrated and adjusted independently, simplifying the manufacturing and assembly process while maintaining overall system accuracy. The segmentation allows for easier quality control and simpler individual part manufacturing.

AI summary
An apparatus for visually indicating attitude of an aircraft in flight is disclosed. The apparatus includes an aircraft model, a cross-shaped LED lamp, a dome filled with damping fluid, a vertical tube, an earth model, and a laser pointer. The apparatus is installable into a cockpit of an aircraft and allows a pilot of the aircraft to see the flight attitude of the aircraft indirectly through the apparatus. Particularly, the apparatus is used under emergency conditions, such as when the internal attitude instrument is out of order and the external environment cannot be effectively visualized. Thus, the apparatus provides a safety guarantee in situations of manual flight in low visibility.
