# FAA expands SMART traffic planning across U.S. airspace

> A broader role for human-reviewed traffic planning.

The FAA said on November 10 that SMART would expand to airspace managed by all 22 U.S. centers. This describes geographic use, not separate local installations.

SMART stands for Strategic Management of Airspace, Routes and Trajectories. In its September launch, the FAA described an AI-supported engine that combines information to anticipate congestion and weather problems. Its purpose is to help people plan, rather than fly an aircraft.

### The big change

- Nationwide expansion follows limited Washington-area use. The relevant change is where the planning advice can be used; a claim about airspace coverage does not establish installation at every facility.
- The September announcement leaves decisions with people. Local air traffic leaders can accept or pass on suggestions, and SMART cannot replace controllers or take control of an aircraft.
- Reported averages need a comparison to be useful. Without knowing how the reference case was chosen, a reader cannot tell whether an apparent improvement would hold under different conditions.

### How advice reaches a decision

The [November statement](https://www.faa.gov/newsroom/statements/general-statements) describes 200 data streams, including weather, flight paths, traffic and staffing. Washington specialists analyze and validate data, sending scheduling recommendations to the command center in Warrenton, Virginia, which passes them to local leadership for consideration.

The FAA's [September explanation](https://www.faa.gov/newsroom/trumps-transportation-secretary-sean-p-duffy-delivers-state-art-air-traffic-control) describes why advance planning matters: when scheduled demand exceeds available airspace capacity, congestion builds. Weather can reduce that capacity further. The agency says SMART helps staff anticipate these constraints rather than waiting for disruption.

Consider a forecast storm that reduces the space available for a planned flow of flights. An alternative route might be considered before congestion develops. This is an illustration of the planning problem, not an observed SMART recommendation or a guarantee that a delay can be avoided.

### Reading the early figures

Since September 21, the FAA reports 180 reroutes and average savings of 10 minutes and almost 80 gallons per flight. Its statement gives no comparison baseline or calculation method; these are agency claims, not independently verified nationwide effects.

An average is a summary of a particular set of observations. It does not tell a traveler what will happen on a future journey, and a change in routing is not the same outcome as a change in ticket price. Understanding the comparison requires knowing which observations were included and what would otherwise have happened.

### Oversight and earlier plans

In an [October 9 letter](https://www.vanhollen.senate.gov/news/press-releases/van-hollen-joins-mcclain-delaney-colleagues-in-call-to-pause-faas-ai-tool-at-washington-area-airports), lawmakers asked for a pause while the FAA and Transportation Department answered questions about safety testing, staff training and oversight. They described a planned 90-day evaluation before nationwide deployment and asked what measures would determine success. Those are oversight requests, not a finding that SMART caused an incident or is unsafe.

The letter's timetable is the lawmakers' account; the November statement does not explain how that evaluation relates to expansion.

The FAA's [June plan](https://www.faa.gov/newsroom/modern-skies-trumps-transportation-secretary-sean-p-duffy-selects-air-space-intelligence) placed SMART within its proposed flow-management system. It described coordinating schedules and trajectories before departure, drawing on weather, airport capacity and operational constraints. The concern is therefore broader than drawing a different line for one flight: changes in demand and capacity can affect traffic elsewhere in the network.

A useful evaluation needs to separate the quality of a forecast from what people do with it. The lawmakers specifically asked how accepted or overridden recommendations would be tracked, what training staff received and who would provide oversight. Recording those steps would make it possible to examine how advice becomes action, rather than treating the presence of a human reviewer as the end of the assessment.
