Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft wake vortices pose a hazard to other aircraft due to turbulence, necessitating a system to detect and alert pilots of potential encounters.
Innovation Solution
A system that receives aircraft and environmental information to generate and modify a wake volume model, determining if the ownship aircraft will coincide with the wake vortex, and displays a representation to the pilot to facilitate evasive action.

Engineering Contradiction Analysis
1Reliability
If a wake vortex detection system is implemented to alert pilots of turbulence hazards, then flight safety is improved, but the system complexity and cost increase
Solution Approach 1:
The wake vortex detection system segments the monitoring task by dividing the airspace into multiple zones (first wake vortex zone, second wake vortex zone, third wake vortex zone) with different detection requirements and alert priorities. This allows the system to focus computational resources on specific regions where wake vortices are most likely to occur, reducing overall system complexity while maintaining safety
Solution Approach 2:
The system performs preliminary detection and classification of wake vortex conditions before they become hazardous. By continuously monitoring aircraft positions, velocities, and environmental factors in advance, the system predicts potential wake vortex formation and issues alerts before turbulence affects the ownship aircraft, improving safety without requiring complex real-time intervention systems
2Measurement precision
If continuous monitoring of nearby aircraft is performed to predict wake vortex encounters, then detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The system applies local quality by intensifying monitoring efforts in specific local zones where wake vortices are predicted to form or persist. Instead of uniformly monitoring all surrounding airspace, the system concentrates detection resources in the first, second, and third wake vortex zones based on environmental conditions and nearby aircraft characteristics, improving detection accuracy while reducing overall energy consumption
Solution Approach 2:
The system dynamically changes monitoring parameters such as detection sensitivity, update frequency, and zone boundaries based on environmental conditions (wind speed, temperature, humidity) and traffic patterns. When wake vortex conditions are unlikely, the system reduces monitoring intensity to conserve energy; when conditions favor vortex formation, detection accuracy is enhanced through increased parameter sensitivity

AI summary
A system for displaying wake information to a pilot of an ownship aircraft. The system includes a display and a receiver. Aircraft information is received, which includes an aircraft type, position and velocity data and aircraft configuration information for a nearby aircraft. Environmental information is also received. The system includes a processor module configured to generate, using the received aircraft information, a wake volume model for the nearby aircraft; and to modify, and using the received environmental information, the generated wake volume model; and to determine if the modified wake volume model will coincide with the ownship aircraft at a future time. When the processor module determines that the modified wake volume coincides with the ownship aircraft at a future time, the processor module is configured to cause the display to display a representation of the modified wake volume.
