Ground Collision Avoidance System Using Transceiver Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flight crews lack visual and aural indications of traffic, objects, or features on the ground, making it difficult to assess situational awareness and preventing collisions, especially in poor visibility conditions.
Innovation Solution
A collision avoidance system for host aircraft on the ground, comprising a processor, transceiver, and memory that generates alerts and displays information about nearby aircraft and ground features, using a transceiver to receive and transmit data, and employing geometric awareness shapes to determine potential collision risks and provide aural and visual warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight crews rely on visual sighting and VHF/UHF communications to detect traffic, then the system remains simple and costs are low, but situational awareness is insufficient and collision risk increases in poor visibility conditions
Solution Approach 1:
The patent introduces a transceiver as an intermediary device that automatically receives and transmits traffic information between aircraft and ground control. This mediator handles the complex communication protocols and data processing, relieving the flight crew of manual monitoring tasks while providing reliable, automated situational awareness without requiring complex manual systems
Solution Approach 2:
The patent replaces the mechanical/physical system of visual sighting with an electronic information system. Instead of relying on human eyes and VHF/UHF radio communications, the system uses automated transceivers to receive, process, and display traffic data electronically, substituting electronic automation for manual visual detection methods
2Measurement precision
If flight crews visually sight traffic on the runway, then no additional equipment is needed, but detection range is limited and traffic at long distances or in poor visibility cannot be seen
Solution Approach 1:
The patent transitions from two-dimensional visual detection (what can be seen with the naked eye) to a multi-dimensional information space where traffic data is received, processed, and displayed electronically. The system adds temporal dimension by continuously updating traffic positions and spatial dimension by displaying multiple aircraft simultaneously, overcoming the limitations of human visual range and conditions
Solution Approach 2:
The patent creates an electronic copy or representation of the actual traffic situation. Instead of directly observing physical aircraft, the transceiver receives data about aircraft positions, speeds, and trajectories, then displays this information as symbolic representations on a display unit, allowing the crew to perceive traffic beyond visual limitations
Data Source
AI summary
A delineated collision avoidance system may comprise a processor for executing one or more instructions that implement one or more functions of the collision avoidance system, a transceiver for transmitting information from and receiving information for the host aircraft, and memory for storing the one or more instructions for execution by the processor to implement the one or more functions of the collision avoidance system to: receive from the transceiver information from another aircraft, generate from the received information a track for the other aircraft, and determine whether the track will intersect within a predefined period of time a region of interest around the host aircraft. In a variation, the system may include a display and the memory may include instructions to: determine whether a predefined condition is satisfied and change an appearance of a symbol shown on the display to indicate that the predefined condition is satisfied.
