Air travelers are often the first to feel the effects when a federal shutdown or funding lapse disrupts the aviation system. 

The most visible symptoms include: 

• Longer lines
• Delayed flight
• Higher costs
• Renewed concerns about system strain 

But they tell only part of the story.

Behind what passengers see at the checkpoint and gate are the teams that keep the national airspace system operating safely and efficiently, such as: 

• Staffing
• Oversight
• Certification
• Infrastructure
• Security functions 

The most recent partial Department of Homeland Security shutdown offered a clear example. It lasted 11 weeks and disrupted airport-facing agencies, including the Transportation Security Administration (TSA), before ending on April 30 with legislation to fund key agencies through September 30. 

By that point, according to Reuters, more than 1,000 TSA officers had departed. 

Why aviation depends on continuity

Aviation cannot simply pause during a funding lapse and resume without consequence. It is an interconnected ecosystem, and a disruption in one area can slow the movement of people, goods and services across the entire system.

When appropriations break down, the disruption is not confined to one agency or one segment of the industry. The effects ripple through a complex infrastructure already working to keep pace with challenges like:

• Rising demand
• Workforce shortages
• Modernization needs
• Higher operating costs

Air traffic controller staffing is one of the clearest examples. 

The Government Accountability Office (GAO) reported that the Federal Aviation Administration (FAA) ended fiscal year 2025 with 13,164 air traffic controllers, about 6% fewer than in 2015, while total flights using the air traffic control system increased about 10% between fiscal years 2015 and 2024. 

That imbalance is significant because safety and efficiency depend on adequate capacity. When demand exceeds capacity, the system becomes less efficient, delays become harder to manage and overtime and fatigue add to operational strain. 

For the general aviation industry, the effects are not abstract. A funding lapse can cause issues like:

• Slowed inspections
• Delayed approvals
• Interrupted federal support
• Less planning confidence for businesses

The need for a more stable funding path is clear. 

Congress provided some certainty for FAA operations earlier this year by approving full-year Department of Transportation funding. But the more recent Department of Homeland Security funding lapse showed that aviation remains vulnerable when other airport-facing agencies, including TSA, are caught in separate budget fights.

That is why the Aviation Funding Stability Act of 2025 deserves serious consideration. The measure would provide continuing appropriations to the FAA from the Airport and Airway Trust Fund during a lapse in appropriations, allowing programs, projects and activities funded in the prior fiscal year to continue for up to 30 days or until regular appropriations are enacted. 

For an industry that depends on continuity, that kind of protection is a practical safeguard for the national airspace system and the communities, businesses and public services it supports. 

Why shutdowns leave lasting strain 

The FAA’s 2023 National Airspace System Safety Review Team found that the 2013 sequestration cuts and 16-day shutdown suspended controller hiring for 10 months and that training was also suspended during the shutdown. 

The 2018-19 partial shutdown again suspended hiring and training, followed by a four-month closure of the FAA training academy and an eight-month pause in training during the pandemic. Together, those disruptions halted hiring for more than a year and training for roughly two of the last 10 years.

That lost time cannot be recovered quickly. Training an air traffic controller is not a short-term staffing exercise but a multi-year process. 

Per the FAA’s  2026-28 Air Traffic Controller Workforce Plan, it can take more than two years to fully certify a new-hire controller depending on the complexity of the assigned facility. 

With approximately 11,000 certified professional controllers deployed across more than 300 FAA air traffic as of April 2026—and about 4,000 more controllers still in the training pipeline—the system depends on steady progress from recruitment to certification. 

Any interruption can slow that progress at the very time additional capacity is needed.

The FAA is working to rebuild that pipeline through a hiring plan for air traffic controllers that aims to increase the workforce by: 

• 2,200 new controllers in fiscal year 2026
• 2,300 in fiscal year 2027
• 2,400 in fiscal year 2028

It also focuses on expanding training partnerships with colleges and technical schools, improving placement of graduates in facilities with the greatest need and using simulator-based training to increase proficiency and reduce new-controller training times by up to 27%.

Still, hiring alone does not immediately solve the shortage. New controllers still must move through stages like:

• Academy training
• Facility training
• Certification
• Attrition

A funding lapse may delay start dates and slow an already limited training and certification pipeline that has high standards and little margin for further disruption. The same concern applies to other FAA safety and oversight functions. 

During the 2018-19 shutdown, the FAA took action to bring back furloughed employees for certain safety-related functions, including:

• Airman medical certifications
• Evaluations
• Audits
• Inspections
• Safety certification activities

Even when essential work continues, the system does not operate normally. The longer a lapse continues, the more pressure falls on FAA personnel, airports and aviation businesses to manage risk, prevent backlogs and keep critical timelines moving. 

For an airport sponsor, this can translate into spending more time managing uncertainty and less time advancing the safety, security and infrastructure priorities that strengthen the field for tenants, operators and the surrounding community.

How cost pressures affect access

Budget instability also affects infrastructure and modernization. Those disruptions may be less visible than long security lines, but they can erode capacity and resilience over time. 

General aviation often feels those effects early, in the form of: 

• Postponed projects
• Disrupted oversight
• Growing uncertainty around leases, capital improvements and operational investments

Airport economics add another layer of strain. Airports carry significant fixed and capital costs tied to areas like: 

• Safety
• Security
• Airfield maintenance
• Staffing
• Infrastructure

When activity levels shift or costs rise, those pressures must be managed through budgets, rates, fees and long-term capital planning. A major challenge is to preserve access while funding the infrastructure required for safe and efficient operations. 

As part of that cost-recovery equation, a growing number of airport sponsors are looking more closely at landing fees and other user charges. 

While these fees may be intended to support airport operations and infrastructure, they also affect the cost of doing business for airport tenants, users and operators already managing higher costs for:

• Labor
• Insurance
• Fuel
• Maintenance
• Compliance

Congress has every right to debate spending priorities, but essential aviation functions should not become collateral damage in unrelated political stalemates. 

For general aviation, the consequences are practical. General aviation works because thousands of people carry out their responsibilities every day with discipline and expertise. They keep airports safe, aircraft moving, businesses operating and communities connected. 

Washington should not make that work harder by allowing essential aviation functions to be disrupted by the next budget impasse.
