Aircraft Orientation Cue Integrating Roll, Pitch, and Yaw
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft display systems are cognitively demanding during zero-zero landings as they do not effectively integrate roll, pitch, and yaw information, which are crucial for maintaining situational awareness and aircraft control.
Innovation Solution
A display system that includes a sensor system, a processor, and a display device, which dynamically generates and displays an aircraft orientation cue as a symbolic polygon that visually conveys roll, angle of attack, and yaw information, allowing for integrated and intuitive presentation of these critical flight parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If disparate flight information (roll, pitch, yaw) is displayed in varying locations and formats on the display, then each parameter can be individually displayed with appropriate detail, but the pilot's cognitive demand increases and situational awareness becomes difficult to maintain
Solution Approach 1:
The patent combines roll, pitch, and yaw information into a single integrated aircraft orientation cue displayed as a unified graphic element. This merging of previously disparate information into one visual unit reduces the pilot's cognitive load by eliminating the need to mentally integrate separate indicators while preserving complete flight parameter information.
Solution Approach 2:
The aircraft orientation cue serves multiple functions simultaneously: it displays roll angle, pitch angle, and yaw information all in one graphic element. This multi-functional design allows a single visual indicator to replace what would traditionally require multiple separate displays, reducing clutter and cognitive demand.
2Loss of information
If multiple separate indicators are used for roll, pitch, and yaw information, then each parameter can be displayed independently, but the display becomes cluttered and information integration becomes mentally demanding
Solution Approach 1:
The patent merges roll, pitch, and yaw indicators into a single integrated aircraft orientation cue. This unified graphic element maintains complete flight information while dramatically simplifying the display layout from multiple separate indicators to one cohesive visual element.
3Ease of operation
If traditional head-up displays are used, then the transition from instrument flying to visual landing is helped, but all required information for zero-zero landing is not provided
Solution Approach 1:
The aircraft orientation cue provides universal flight information coverage by displaying roll, pitch, and yaw data simultaneously in a single integrated graphic. This multi-functional indicator supplies all necessary information for zero-zero landing while maintaining the ease of transition to visual landing through its prominent display.

AI summary
An improved aircraft display system and method that generates an aircraft orientation cue are provided. The aircraft orientation cue may be displayed in a variety of panoramic and landscape displays, and on head up and on head down display. The aircraft orientation cue has a symbolic form sufficient to visually convey, simultaneously, and in a predetermined manner, each of the AOA, roll, and yaw of the ownship A/C.
