Navigation Procedure Display System for Aviation Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic flight bags (EFBs) struggle to replicate paper charts effectively on electronic displays, leading to overlapping symbols and reduced readability due to the limitations of two-dimensional navigation in aviation and underwater applications, which require four-dimensional concepts and critical procedural information depiction.
Innovation Solution
A data-driven navigation procedure display system that includes a dynamic information area and a moving map area, allowing for the display of current and successive procedure instructions in three dimensions, with situational awareness symbols and adjustable layout to enhance readability and clarity, using a computing device and input devices like touch screens or rotary dials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If paper charts are replicated on electronic displays, then electronic flight bags can provide navigation information digitally, but symbols may overlap and text leader-arrows may collide during rotation
Solution Approach 1:
The patent transitions from two-dimensional paper chart representation to three-dimensional spatial rendering on electronic displays. By incorporating depth perception and multiple display planes, the system eliminates symbol overlap and collision issues that plague flat electronic representations, while maintaining the digital adaptability benefits.
Solution Approach 2:
The system dynamically adjusts the display representation based on the aircraft's orientation and flight parameters. Rather than static rotated images that cause text and symbol collisions, the display continuously adapts its configuration to maintain optimal readability during all phases of flight.
2Adaptability or versatility
If traditional two-dimensional navigation displays are used, then electronic displays can be implemented, but they fail to provide adequate situational awareness for four-dimensional aviation navigation
Solution Approach 1:
The patent explicitly adds the fourth dimension (time) to the traditional three-dimensional spatial navigation display. By incorporating temporal information such as time of arrival predictions and dynamic procedure sequencing, the system provides complete four-dimensional situational awareness required for modern aviation navigation.
Solution Approach 2:
The display system nests multiple levels of navigation information within each other, from macro-level procedure overview to micro-level positional details. This hierarchical nesting allows pilots to access comprehensive four-dimensional navigation data without information overload, maintaining clarity while providing complete situational awareness.
3Ease of manufacture
If fixed format electronic displays are used, then implementation is simpler, but they cannot provide extended navigation capabilities beyond paper charts
Solution Approach 1:
The patent creates a universal display system that can present multiple types of navigation information in various formats depending on the phase of flight and procedural requirements. The same hardware platform adapts to display different navigation procedures, approaches, and departure routes, providing extended capabilities without requiring multiple specialized display systems.

AI summary
A navigation procedure display (200) is described. The navigational procedure display includes a dynamic information area (204), positioned within the flight procedure display, for displaying a current procedure (240) instruction and at least one successive procedure instruction (242). The navigational procedure display also includes a moving map area (202), positioned within the procedure display (200), for displaying a current position indication (206) in at least three dimensions and situational awareness symbols (210, 212).
