Q&A with Dr. Bedan Thendu

Q: Air navigation has evolved tremendously over the decades. If you could predict the biggest transformation in ANS over the next 10 years, what would it be?

Dr. Thendu: The biggest transformation in ANS over the next decade will be the actualization of Trajectory-Based Operations (TBO). This concept involves the continuous sharing and optimization of flight trajectories throughout all phases of a flight, enhancing predictability, flexibility, safety, and efficiency.

As global airspace faces increasing capacity and demand limitations, TBO will help accommodate traditional manned aviation alongside new entrants such as unmanned aircraft systems (UAS), high-altitude balloons, hybrid and electric aircraft, supersonic and hypersonic jets, and advanced air mobility (AAM) solutions. The integration of automation, robotics, artificial intelligence (AI), and the Internet of Things (IoT) will be instrumental in shaping the future of ANS.Aviation will increasingly rely on real-time access to aeronautical, flight, weather, and surveillance data. Tactical air traffic control instructions will evolve into strategic clearances issued via data communications, enabling a more coordinated and situationally aware air traffic management system. Key enablers like Flight and Flow Information for a Collaborative Environment (FF-ICE), Airport Collaborative Decision Making (ACDM), and System Wide Information Management (SWIM) will drive this evolution. While this transformation won’t happen overnight, it will significantly disrupt the industry over time.

Q: Having worked on multiple national air navigation master plans, what are the most common mistakes you see states making when designing or modernizing their ANS infrastructure?

Dr. Thendu: That’s a really good question. Some of the most common mistakes I’ve seen include:

• Lack of technical expertise: Master plans developed by non-specialists often fail to identify appropriate strategic objectives, leading to misplaced priorities and ineffective infrastructure investments.
• Poor stakeholder collaboration: Insufficient coordination with industry players results in a lack of user buy-in and misaligned priorities.
• Budget constraints and bureaucratic challenges: Even well-designed master plans may fail due to inadequate funding, government bureaucracy, or political interference.
• Neglecting workforce development: The absence of dedicated resources for training personnel undermines the implementation and utilization of modernized infrastructure.

To ensure long-term success, states must integrate technical expertise, foster collaboration, secure stable funding, and invest in workforce development as part of their ANS modernization efforts.

Q: With increasing AI, automation, and satellite-based navigation, do you think traditional air traffic controllers will ever become obsolete? Or will human oversight always be essential?

Dr. Thendu: While automation will significantly enhance efficiency, air traffic controllers will continue to play a vital role. In Trajectory-Based Operations, controllers will focus on negotiating optimized flight trajectories and issuing strategic clearances. While automation will reduce the need for tactical interventions, human oversight will remain critical, particularly in responding to abrupt weather changes, equipment failures, or unforeseen disruptions.

The rise of Digital Aerodrome Air Traffic Services (DAATS) will also enable remote air traffic management, extending controllers' reach beyond physical airport locations. Rather than becoming obsolete, air traffic control will evolve into a more strategic and data-driven function.

Q: What are the biggest bottlenecks to seamless Air Traffic Management (ATM) integration across different regions?

Dr. Thendu: There are several challenges players will face when trying to achieve a harmonized global ATM system.

• Diverging national priorities: States have different modernization timelines and investment strategies, creating inconsistencies in implementation.
• Political barriers: Regional disputes and governance issues can slow down integration efforts.
• Funding and resources: Many states struggle to allocate sufficient financial and technical resources to ATM projects.
• Regulatory misalignment: Inconsistent regulatory frameworks hinder interoperability across borders.

To overcome these challenges, states should strengthen regional cooperation, align national development plans with global initiatives, and establish multilateral frameworks to facilitate ATM integration.

Q: You were involved in Somalia's airspace transition. What were the biggest challenges in upgrading a country’s airspace classification, and what lessons can others learn?

Dr. Thendu: Somalia’s airspace transition improved safety and operational efficiency but came with key challenges:

• Inadequate infrastructure: Limited communication and navigation systems required significant upgrades.
• Lack of skilled personnel: Training programs were essential to developing local expertise.
• Coordination with neighboring FIRs: Effective collaboration with adjacent Flight Information Regions (FIRs) was necessary for seamless integration.
• Civil-military cooperation: Ensuring national security while enabling cost-efficient operations was a delicate balance.

The key takeaway is that successful airspace transitions require robust infrastructure investments, workforce development, regional cooperation, and regulatory alignment.

Q: With the rise of UAVs, cyber threats, and unpredictable weather patterns, what emerging risks keep ANS professionals awake at night, and how should the industry prepare?

Dr. Thendu: All of these are extremely valid risks. I always encourage folks to think about:

• Safe integration of UAVs: Unmanned aircraft must be incorporated without compromising existing airspace operations.
• Cybersecurity vulnerabilities: Increasing digitization makes aviation more susceptible to cyberattacks.
• Climate-related disruptions: More frequent severe weather events require enhanced predictive capabilities and adaptive air traffic management systems.

Regulatory frameworks must evolve to keep pace with technological advancements. Performance-based regulation, rather than prescriptive rules, will provide the flexibility needed to address emerging risks while maintaining safety and efficiency.

Q: How do you balance the harmonization of ICAO global standards with the unique operational, economic, and political realities of different states?

Dr. Thendu: ICAO provides a standardized framework, but states have flexibility in tailoring these regulations to fit their national priorities. The key to effective implementation lies in:

• Aligning global standards with national aviation policies.
• Leveraging ICAO regional offices and expert guidance.
• Seeking technical assistance to bridge capability gaps.
• Ensuring regulatory convergence to facilitate cross-border operations.

States that integrate ICAO standards into their national frameworks while adapting to local contexts will achieve both compliance and operational efficiency.
