UAS Flight Boundary Limiting Control for Restricted Airspace
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for unmanned aerial systems (UAS) lack reliable means to prevent midair collisions with manned aircraft, as they cannot physically prevent UAS from entering restricted airspace, posing a catastrophic risk.
Innovation Solution
A flight limiting controller (FLC) system that determines the UAS's position relative to flight boundaries and activates limitations such as warnings, autopilot commands, parachute deployment, or propulsion device adjustments to prevent crossing of prohibited areas, ensuring a high system integrity of at least 1*10−7 to prevent collisions.

1Reliability
If flight limitation functions are made highly reliable with system integrity of at least 1*10−7 to prevent catastrophic midair collisions, then safety is improved, but the cost and complexity of the UAS system increases
Solution Approach 1:
The supervisory controller is segmented into distinct functional modules: GPS position acquisition module, boundary data storage module, position comparison module, and flight limitation control module. This segmentation allows each component to be independently designed, tested, and validated for reliability while maintaining overall system integrity of at least 1*10−7 without excessive complexity.
