Mapping Every Understaffed Air Traffic Control Tower In The US

Earlier this year, the U.S. experienced one of its deadliest air mishaps in two decades.

An American Airlines passenger plane collided with a U.S. Army Black Hawk helicopter sending both into the Potomac River.

ℹ️ For reference: American Airlines has one of the worst track-records when it comes to crashes.

In the immediate aftermath, officials mentioned that short-staffed air traffic control towers may have played a role. This was later deemed not the cause, but air traffic control staffing shortages are plaguing 44% of all FAA regulated towers, latest data shows.

Visual Capitalist's Pallavi Rao maps out every single tower that is below the 2024-guideline staffing threshold (85%) per the latest available data current to September 2023, published by the FAA.

Ranked: All Short-Staffed Air Traffic Control Towers

128 of the 290 FAA-operated air traffic control towers across the country are short-staffed.

Rochester Tower, located in Minnesota has less than half the required controllers per 2024 requirements.

Of particular interest are the short-staffed TRACONs (Terminal Radar Approach Control); these are bigger facilities that assist with landing and departure for larger areas.

In fact, these numbers are a more optimistic view of the staffing shortage. They include fully-certified controllers, those that have transferred from a different facility and getting familiar with a new environment, and those just out of academy who are picking up on-the-job skills.

If looking at just the fully certified controllers, these rates drop even further.

For reference, it takes roughly 2–3 years for an academy graduate to become fully certified.

Why is There an ATC Staffing Shortage?

There are a few interlinked reasons.

As a mentioned earlier, it’s a difficult (and long) training process, which takes a minimum of 2-3 years. The COVID-19 pandemic interrupted or paused training and now the system is playing catch-up.

The attrition rate of employees is high due to long hours and on-the-job stress. And finally, there’s a mandatory retirement age (56) which leads to a yearly employee loss.

This shortage is pushing controllers into 60-hour workweeks, in turn leading to a higher burnout rate.
