Aircraft Map Display Unit with Periodic Own Ship Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft cockpit displays using electronic flight bags lack regulatory approval for primary navigation due to the misuse of own ship depictions on maps, which are not approved for continuous display, necessitating a transition from paper-based operational procedures to electronic systems while ensuring compliance with navigation standards.
Innovation Solution
A position indicating display system that includes a map display unit showing an aircraft's current position with an own ship depiction, controlled by user input or aircraft sensors, allowing temporary display to prevent misuse and comply with regulatory requirements, featuring a database, aircraft position receiver, display unit, processor, and input device for generating and overlaying the aircraft's position on a digital map.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If own ship depiction is continuously displayed on electronic enroute maps, then situational awareness is improved, but regulatory approval is lost due to misuse as primary navigation display
Solution Approach 1:
The system implements periodic display of own ship depiction by detecting pilot input actions (such as controller movements or button presses) and displaying the own ship symbol only during specific time windows after detected inputs, rather than continuously. This periodic display maintains situational awareness benefits while complying with regulatory requirements that prohibit continuous display.
Solution Approach 2:
The system uses the pilot's own input actions (controller movements, button presses, touchscreen interactions) as the trigger mechanism for displaying own ship depiction. The display is activated self-service style based on pilot behavior patterns, eliminating the need for separate control inputs while maintaining compliance through intelligent detection of when display is actually needed for situational awareness.
2Ease of operation
If own ship depiction is displayed on electronic maps, then ease of operation is improved, but device complexity increases to prevent misuse
Solution Approach 1:
The system implements feedback mechanisms by monitoring pilot inputs (controller position changes, button presses, touchscreen interactions) and using this feedback to control the display of own ship depiction. The system detects when the pilot interacts with the flight control system and automatically displays or hides the own ship symbol based on these detected actions, creating an intelligent feedback loop that simplifies operation while managing complexity through software-based control.

AI summary
Methods and systems for a position indicating display system for an aircraft are provided. The system includes a map display unit configured to display a map representative of an area being traversed by the aircraft, and an overlay comprising an own ship depiction, said overlay displayed on the map for a period of time in response to an input from at least one of a user and an aircraft sensor.
