Automatic Display Range Control for Airport Moving Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft cockpit displays require manual range control for moving maps, which distracts crew from primary responsibilities, introduces undesirable workload, and fails to optimally display important information due to discrete and fixed display range selections, limiting situational awareness and safety.
Innovation Solution
An automatic display range control system that adjusts display settings based on vehicle position, proximity, and orientation to objects and areas of interest, optimizing the view of approach runways, traffic, and other critical information without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual crew display range control is used, then discrete and fixed display range selections are provided, but crew workload increases and primary responsibilities are distracted
Solution Approach 1:
The system automatically adjusts display range based on aircraft position and operational phase without requiring manual crew intervention. The autorange function monitors aircraft state and autonomously selects optimal display ranges, eliminating the need for crew to manually control display parameters while maintaining situational awareness
Solution Approach 2:
The system dynamically changes display range parameters based on aircraft position, operational phase, and detected objects. Instead of fixed discrete selections, the display range continuously adapts to current flight conditions, providing optimal visualization automatically
2Ease of operation
If discrete and fixed display range selections are used, then manual setting is simplified, but optimum display of approach runway and important information is prevented
Solution Approach 1:
The display range transitions from static fixed selections to dynamic continuous adjustment. The system automatically varies display range based on real-time aircraft position and operational context, ensuring important information such as approach runways and traffic remain visible without manual intervention
Solution Approach 2:
The system continuously monitors aircraft position, operational phase, and detected objects to provide feedback for automatic display range adjustment. This closed-loop control ensures the display always shows optimal information for current flight conditions without requiring crew input
3Ease of operation
If manual display range setting is used, then crew has control over display content, but traffic and areas beyond display range are precluded from view
Solution Approach 1:
The system proactively detects objects and areas beyond current display range and automatically adjusts range to include them before they become critical. This preliminary action ensures traffic and important areas are visible in advance, enhancing situational awareness without requiring manual scanning or adjustment

AI summary
Methods and systems for presenting a current position of a vehicle on a moving map display are provided. The method includes determining a current position and a path of travel of the vehicle, determining a current position of at least one of a second vehicle, an object, and an area of interest wherein determining a current position of the second vehicle includes determining a path of travel of the second vehicle, and displaying a depiction of the vehicle and at least a portion of the at least one of the second vehicle, the object, and the area of interest at a first range setting. The method further includes automatically changing from the first range setting to a second range setting based on at least one of an approach autorange activation, an offscale traffic activation, and an offscale object or area of interest autorange activation, and displaying the ownship depiction and at least a portion of the at least one of the second vehicle, the object, and the area of interest at the second range setting.
