FAA Launches Common Automation Platform to Modernize Air Traffic Control

The Shift Toward a Common Automation Platform

The Federal Aviation Administration (FAA) has officially launched a significant initiative to overhaul the technological backbone of the National Airspace System (NAS). In a move designed to modernize air traffic control, the agency is seeking a “Prime Integrator” to develop and implement a new Common Automation Platform (CAP). This initiative represents a strategic pivot away from the current segmented architecture, aiming to replace legacy systems with a unified, cloud-native solution capable of managing the complexities of modern Aviation.

For decades, the management of American airspace has relied on distinct systems for different phases of flight. High-altitude traffic is currently managed by the En Route Automation Modernization (ERAM) system, while traffic approaching and departing Airports is handled by the Standard Terminal Automation Replacement System (STARS). While these systems have served their purpose, the FAA has identified the need for a singular, integrated environment. We observe that this transition is not merely a software update but a fundamental restructuring of how air traffic data is processed, shared, and displayed to controllers.

The timing of this initiative aligns with broader infrastructure concerns. Following a comprehensive audit by the Government Accountability Office (GAO) in September 2024, the urgency to address aging infrastructure has become a focal point for the agency. The move toward a Common Automation Platform is intended to resolve Sustainability issues found in legacy hardware while preparing the NAS for the integration of new airspace entrants, such as commercial space vehicles and Advanced Air Mobility (AAM) operators.

Addressing Infrastructure and Sustainability Challenges

The impetus for this modernization effort is heavily supported by data regarding the current state of FAA technology. The September 2024 GAO report provided a critical assessment of the agency’s infrastructure, revealing that a significant portion of the systems currently in use are facing sustainability challenges. Specifically, the report noted that 51 of the FAA’s 138 systems, approximately 37 percent, are considered unsustainable. These findings highlight risks associated with aging hardware, a scarcity of spare parts, and reliance on legacy code that is increasingly difficult to maintain.

We see that the current reliance on separate systems for En Route and Terminal environments creates what is often described as operational fragmentation. Currently, a controller managing an aircraft at cruising altitude uses a completely different interface and command syntax than a controller handling the same aircraft’s approach to a runway. This disparity requires controllers to master two distinct operating systems, potentially increasing the training burden and creating friction during the transfer of control. The proposed CAP aims to eliminate this “balkanization” by providing a unified interface, streamlining operations across all domains of flight.

Furthermore, the resilience of the National Airspace System is a primary objective of the CAP initiative. Under the current architecture, physical facilities are often tied to specific blocks of airspace. The FAA’s vision for the new platform includes “location independence,” a capability that would allow air traffic control services to be provided from alternative facilities if a specific center goes offline. This redundancy is critical for mitigating the impact of outages and ensuring continuity of operations during technical failures or natural disasters.

The GAO report from September 2024 highlighted that 37% of the FAA’s systems are currently viewed as unsustainable, underscoring the critical need for a unified modernization strategy.

Integrating Future Airspace Entrants

Beyond fixing current infrastructure limitations, the Common Automation Platform is being designed with future scalability in mind. The aviation landscape is evolving rapidly with the introduction of non-traditional entrants. We are witnessing an increase in commercial space launches, the development of drone delivery networks, and the impending arrival of eVTOL aircraft. Legacy systems like ERAM and STARS were not originally architected to handle the dynamic trajectories and data requirements of these new vehicle types.

The Request for Information (RFI) issued by the FAA indicates a requirement for a system that can seamlessly integrate these diverse operations. A unified platform would allow for better trajectory modeling and data sharing, essential for the safe coexistence of traditional commercial airliners and new aerospace technologies. By moving to a cloud-native or open architecture, the FAA aims to create a system that is easier to upgrade, allowing for faster adoption of future technological advancements compared to the rigid cycles of the past.

This forward-looking approach also mirrors trends observed in global air traffic management. Other Air Navigation Service Providers (ANSPs) worldwide, such as Skyguide in Switzerland and NATS in the United Kingdom, have already begun exploring or implementing “Virtual Centre” concepts and unified platforms. These international examples demonstrate the feasibility of decoupling physical infrastructure from airspace management, a core goal of the FAA’s new initiative.

Market Implications and Implementation

The transition to the Common Automation Platform represents a substantial commercial opportunity within the aerospace and defense sector. The contract to become the Prime Integrator for this system is expected to be one of the most significant technological undertakings of the decade. Incumbent manufacturers, such as Lockheed Martin (manufacturer of ERAM) and Raytheon (manufacturer of STARS), are likely to be key figures in this transition, given their deep institutional knowledge of the current architecture.

However, the shift to an open, unified architecture may also open the door for other major defense contractors and technology integrators. Companies with expertise in cloud computing, large-scale systems integration, and cybersecurity will likely play pivotal roles. The FAA has set a response deadline for the RFI in December 2025, signaling a desire to move relatively quickly in identifying potential solutions and partners.

Implementing such a massive overhaul will not be without challenges. Industry experts have historically warned against “Big Bang” approaches to system replacement, where old systems are swapped for new ones overnight. Instead, a phased implementation is anticipated, where the CAP is introduced gradually alongside legacy systems to ensure safety and stability. The financial commitment required for this modernization is substantial, with estimates suggesting a need for significant congressional funding to fully realize the transition.

Conclusion

The FAA’s pursuit of a Common Automation Platform marks a critical turning point for the National Airspace System. By moving to replace the fragmented ERAM and STARS systems with a unified, resilient, and future-proof architecture, the agency is addressing both the immediate risks identified by the GAO and the long-term needs of a changing aviation industry. The success of this initiative will depend on the selection of a capable Prime Integrator and a carefully managed transition strategy that prioritizes safety above all else.

As the deadline for industry responses approaches in late 2025, the aerospace community will be watching closely. The outcome of this initiative will determine how US airspace is managed for generations to come, influencing everything from daily commercial flights to the integration of space travel and autonomous drones into the national skies.

FAQ

What is the Common Automation Platform (CAP)?
The CAP is a proposed unified air traffic control system intended to replace the FAA’s separate legacy systems (ERAM and STARS). It aims to combine high-altitude and terminal air traffic management into a single, seamless interface.

Why is the FAA replacing ERAM and STARS?
The replacement is driven by the need to address aging, unsustainable infrastructure, improve system resilience, and create a unified interface for controllers. It is also necessary to accommodate future airspace users like drones and commercial spaceflight.

What did the September 2024 GAO report find?
The Government Accountability Office report found that 51 of the FAA’s 138 systems (approximately 37%) are unsustainable due to issues such as lack of spare parts and reliance on outdated code.
