Integrated 3D Flight Attitude Display for Spatial Disorientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots face challenges in making quick and correct judgments about an aircraft's flight attitude relative to the sky and ground, leading to potential spatial disorientation and aviation accidents during emergencies.
Innovation Solution
An aircraft flight attitude display device is developed, comprising a central processing unit (CPU), a display unit, sky and ground obstacle data receivers, flight data receivers, and a power supply unit. The device displays an aircraft image with various flight attitude indicators, such as pitch, roll, and yaw angles, along with obstacle images and flight data, to aid pilots in making accurate judgments.

Engineering Contradiction Analysis
1Measurement precision
If conventional windshields and numerous instruments are used for flight attitude judgment, then the pilot can obtain flight attitude information, but the judgment procedure becomes very complex and time-consuming
Solution Approach 1:
The patent merges multiple flight attitude parameters (pitch angle, roll angle, yaw angle) and obstacle information into a single integrated display showing a three-dimensional aircraft model with visual indicators. This consolidation allows the pilot to obtain comprehensive flight attitude information from one unified interface rather than multiple separate instruments, thereby reducing judgment time while maintaining accuracy.
Solution Approach 2:
The patent transitions from traditional two-dimensional instrument panels to a three-dimensional visual display showing the aircraft model in spatial orientation. This dimensional enhancement provides intuitive visual feedback about flight attitude relative to the horizon and obstacles, enabling faster and more accurate spatial awareness without the complexity of multiple gauges.
2Reliability
If complex judgment procedures are required for flight attitude assessment, then comprehensive flight information can be obtained, but spatial disorientation occurs during emergencies
Solution Approach 1:
The patent employs color-coded visual indicators on the three-dimensional aircraft model to represent different flight attitude states and obstacle positions. Colors provide immediate, intuitive recognition of critical conditions without requiring complex interpretation, thereby maintaining reliability while significantly improving ease of operation during emergency situations.
Solution Approach 2:
The system pre-processes flight attitude data and obstacle information to generate ready-to-interpret visual indicators on the aircraft model. This preliminary processing converts raw sensor data into intuitive visual cues before presentation to the pilot, eliminating the need for complex real-time judgment procedures and reducing cognitive load during critical moments.
3Loss of information
If multiple separate instruments are used for flight parameters, then detailed flight data can be displayed, but the device complexity increases
Solution Approach 1:
The three-dimensional aircraft model display serves multiple functions simultaneously: it shows pitch attitude, roll attitude, yaw orientation, obstacle positions, and flight path information all in one unified visual interface. This multi-functional approach maintains complete flight data presentation while eliminating the need for multiple separate instruments, thereby reducing overall system complexity.
