645. Is the Air Traffic Control System Broken?

Key Takeaways

U.S. air traffic control is remarkably safe but relies on outdated 1950s-era technology.
The system faces severe strain from staffing shortages and increasing air travel demand.
Congressional funding processes and political dynamics hinder modernization efforts.
Proposals to corporatize air traffic control aim to enable business-like investment and operations.
General aviation interests actively resist reforms to the funding structure.

The U.S. air traffic control system manages approximately 5,000 planes in the sky at any moment, with roughly 45,000 flights and over 3 million passengers daily.
The global fatality risk is one in 13 million boardings, significantly lower than 50 years ago.
Recent incidents include a January midair collision (67 dead) and June equipment outages at Newark Liberty Airport, causing communication failures.
The system is analogized to an iPhone 5 compared to other countries' iPhone 18, suggesting it is significantly behind.

The current air traffic control system relies on technology from the 1950s and 60s, including older radar systems instead of satellite navigation.
Congressional funding cycles and political processes hinder necessary modernization, causing a massive backlog of investment needs.
Ed Bastian, CEO of Delta Airlines, describes the system as relying on aging technology and states it is "one day closer to breaking."
The FAA was established in 1958 after a deadly mid-air collision, with early methods progressing from bonfires to post-WWII radar technology.

The shortage of air traffic controllers stems partly from the 1981 PATCO strike, where President Reagan fired 11,000 controllers, and many replacements are now nearing retirement.
Training a new controller takes four to five years, and a lengthy, difficult process, exacerbated by delays like those during COVID-19.
Understaffing at 19 facilities causes 40% of delays, with economists estimating annual costs from shortages at $135 million to $160 million.
Transferring controllers between facilities is complicated by the need for site-specific training.

Economist John Strong explains that 1980s airline deregulation led to lower airfares and increased air travel, but infrastructure development, particularly air traffic control technology, lagged.
The aviation industry recognized problems with outdated ATC infrastructure for decades but was slow to act until recent safety events spurred action.
The FAA's next-generation air traffic control system aims to transition from 1950s ground-based radar to a satellite-based navigation system using GPS, with estimated costs of $40 billion to $50 billion.
Modern compute power, including AI and machine learning, could provide controllers with better, more timely information for air traffic management.

The single FAA training academy in Oklahoma City serves as a bottleneck, though increasing its capacity and utilizing university partnerships could help.
The FAA's $18.5 billion budget is primarily funded (80-85%) by a trust fund generated through ticket taxes and fees, with the remainder from the general fund.
Approximately two-thirds of the budget supports FAA operations, with half allocated to air traffic control, including controller salaries.
Only about 10% of the FAA's $4-5 billion annual budget for air traffic control is allocated for new investment; 90% goes to repairs and maintenance.

Polly Trottenberg explains the complexity of the federal budgeting process, where discretionary funds for the FAA's Facilities and Equipment Account are subject to annual appropriation caps.
This process has led to stagnant funding of around $3 billion for 15 years, hindering necessary modernization efforts for air traffic control.
Despite this, the air traffic control system is described as not in crisis but in urgent need of attention, with recent funding providing a "down payment" for changes.
A comparison is drawn between the highly controlled federal aviation system and the decentralized roadway system's safety challenges.

Dorothy Robyn, a senior fellow at ITIF and former White House economic policy advisor, conducted dissertation work on trucking deregulation, noting similarities to airline deregulation.
Economists advocated for trucking deregulation, which Congress passed due to a coalition of liberals and libertarians, despite opposition from labor and industry.
Airline deregulation in 1978 strategically preceded trucking deregulation in 1980, as the airline industry lacked a powerful union comparable to the Teamsters.
Airline deregulation, initiated by economist Alfred Kahn, led to lower fares and increased demand, which subsequently strained the air traffic control system.

The U.S. air traffic control system, particularly at Newark Liberty International Airport, is facing issues described as "third world," including outdated technology, equipment outages, and fried copper wires.
Dorothy Robyn proposes corporatizing or privatizing air traffic control, noting that nearly 100 countries have adopted such models since the 1990s.
These government corporation models, similar to utilities, allow ATC to operate like a business, secure loans, and avoid federal regulatory constraints.
Photographs reveal outdated radar systems cooled by desk fans and the continued use of paper flight strips in some facilities.

NAV Canada is highlighted as a successful non-profit, user-run air traffic control system that improved efficiency and technology by aligning incentives.
Repeated failures of air traffic control reform efforts are attributed to congressional district interests, past FAA capital investment management struggles, and reluctance to change a system perceived as safe.
General aviation, including private pilots and business jets, obstructs reform, fearing loss of benefits or increased costs for system usage.
Business jets, which use the same airspace as commercial flights, contribute a fraction of the fees while imposing identical costs on the air traffic control system.
