Solution Overview

Problem

Runway incursions at non-towered airports remain a significant safety concern due to the high cost and complexity of existing prevention technologies, which have limited adoption and primarily focus on towered airports, leaving general aviation aircraft vulnerable.

Innovation Solution

A low-cost, low-complexity runway incursion avoidance system utilizing surveillance modules with processors and transmitters to predict occupancy states of runways and broadcast these predictions to status light modules, which control runway status lights using wireless communication protocols, ensuring safety without requiring pilot buy-in or complex infrastructure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing runway incursion prevention technologies are deployed, then runway safety is improved, but system cost and complexity increase significantly

Engineering Contradiction:
Improverunway safetyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system divides the runway into multiple surveillance zones with independent detection modules. Each zone operates autonomously to detect occupancy and communicate status, simplifying the overall system architecture while maintaining comprehensive coverage. This segmentation allows the complex safety function to be achieved through multiple simple, independent units rather than one complex centralized system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The surveillance modules and runway status light modules are self-contained units that independently perform detection, processing, and communication functions. Each module operates autonomously without requiring complex external control infrastructure, reducing system complexity while ensuring reliable safety monitoring through distributed intelligence.

Inventive Principle:
Principle #25Self-service

2Reliability

If existing runway incursion prevention technologies are deployed, then runway safety is improved, but implementation cost increases prohibitively

Engineering Contradiction:

Solution Approach 1:

The system employs inexpensive surveillance modules and status light modules that can be deployed at multiple locations along the runway. These modular units use cost-effective sensors, processors, and wireless communication components, making the overall system affordable for implementation while maintaining high safety standards through redundant coverage.

Inventive Principle:

AI summary

A runway incursion avoidance system includes a plurality of surveillance sub-systems that are configured to detect whether an approach and a surface of an aviation runway is currently occupied or will soon be occupied by an object, such as an aircraft, vehicle, pedestrian, wild animal, or other foreign object. The surveillance sub-systems each broadcast one or more occupancy states of the aviation runway. The runway incursion avoidance system further includes a plurality of runway status light sub-systems that control one or more runway status lights depending on the occupancy states broadcast by the surveillance sub-systems. The runway status lights may include Departure and Approach Warning Lights (DALs) to indicate runway status to aircraft taking off from the runway and landing on the runway, or Runway Entrance Lights (RELs) to indicate runway status to aircraft, vehicles, and pedestrians preparing to cross a runway.
