Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic dependent surveillance-broadcast technology is deployed to meet future aviation demands, then air traffic management efficiency and capacity are improved, but system vulnerability to natural and malicious disruptions increases
Solution Approach 1:
The simulation tool performs security assessments and vulnerability analyses before wide-scale ADS-B deployment. By introducing threats and disruptions into the simulation environment beforehand, the system identifies potential failure modes and enables preventive mitigation strategies to be developed and tested prior to actual deployment.
Solution Approach 2:
The system prepares contingency plans and backup communication protocols in advance based on simulation results. When disruptions occur in the actual ADS-B system, pre-developed mitigation strategies and alternative communication paths are already in place to maintain air traffic management functionality.
2Adaptability or versatility
If shared datalinks are used in automatic dependent surveillance-broadcast to enable aircraft-to-ground and aircraft-to-aircraft communications, then navigation capability in uncertain environments is improved, but exposure to malicious exploitation and data corruption increases
Solution Approach 1:
The simulation tool introduces malicious threats such as data corruption, spoofing, and wireless jamming into the ADS-B communication environment before deployment. By modeling these harmful actions in advance, the system identifies vulnerabilities in shared datalinks and enables development of countermeasures and authentication protocols to prevent malicious exploitation.
3Reliability
If security assessments of vulnerabilities are conducted before deployment, then system safety and reliability are improved, but deployment timeline and complexity increase
Solution Approach 1:
The simulation tool creates a virtual copy of the ADS-B air traffic management system that replicates communication protocols, aircraft behaviors, and airspace operations. This digital twin allows comprehensive security assessments and vulnerability analyses to be conducted in the simulated environment, identifying threats and testing mitigations without affecting the actual deployment timeline or adding physical complexity to the real system.
