FAA Activates 100th Surface Awareness Initiative System

The Federal Aviation Administration (FAA) has activated its 100th Surface Awareness Initiative (SAI) system, marking a halfway point in a nationwide deployment aimed at reducing runway incursions and improving air traffic controller situational awareness. U.S. Transportation Secretary Sean P. Duffy and FAA Administrator Bryan Bedford announced the milestone on September 2, 2026.

In a press release issued by the agency, officials confirmed that the SAI technology is now operational at 100 air traffic control towers. The system leverages Automatic Dependent Surveillance-Broadcast (ADS-B) data to provide controllers with real-time tracking of aircraft and ground vehicles. This capability is particularly critical during periods of low visibility or when portions of the airfield are outside the direct line of sight from the control tower.

Accelerated rollout of surface safety technology

The FAA plans to install the SAI system at a total of 220 airports that previously lacked surface surveillance capabilities. According to the agency, an additional 44 facilities are scheduled to receive the technology by the end of 2026. Recent installations include Ann Arbor Municipal Airport (ARB), Billings-Logan International Airport (BIL), Gulfport-Biloxi International Airport (GPT), Greenville-Spartanburg International Airport (GSP), and Corpus Christi International Airport (CRP).

The accelerated deployment is supported by a $12.5 billion allocation for air traffic control modernization under the Working Families Tax Cut Act.

“We have doubled our deployment speed thanks to Republicans in Congress who delivered funding through the Working Families Tax Cut Act,” Duffy stated. “We’re going to continue fast-tracking our deployment so that all 220 FAA towers that did not have surface surveillance capabilities can now have a new tool at their disposal for controllers.”

Broader air traffic control modernization

The SAI milestone is part of a wider initiative by the U.S. Department of Transportation (DOT) and the FAA to upgrade aging aviation infrastructure. FAA Administrator Bryan Bedford emphasized the operational necessity of the new systems.

“SAI is vital for controllers. It gives them the big picture of the airport’s surface right at their fingertips,” Bedford said. “For our controllers to work at their best, they need the technology to match their expertise.”

The September 2 announcement follows a series of related infrastructure investments. In late August 2026, the FAA highlighted a $27.3 million project to modernize the air traffic control system at Norfolk International Airport (ORF). Duffy and Bedford also recently inaugurated a $40 million Rohde & Schwarz USA manufacturing facility in Frederick, Maryland. The plant will produce digital Voice over IP switches for the national airspace system.

The agency has also continued deploying Surface Movement Radar Model 4 (SMR-4) systems, with recent installations completed at Ronald Reagan Washington National Airport (DCA) and Newark Liberty International Airport (EWR).

AirPro News analysis

The rapid deployment of the Surface Awareness Initiative represents a pragmatic approach to a persistent safety challenge. Historically, advanced surface surveillance systems were limited to the nation’s largest and busiest hub airports due to high installation and maintenance costs. By utilizing existing ADS-B out data, which is already mandated for most aircraft operating in controlled airspace, the FAA can provide smaller and mid-sized regional airports with a digital picture of the airfield at a fraction of the cost. We view this 100-tower milestone as a critical step in closing the technology gap between major international hubs and regional facilities, ultimately creating a more uniform safety standard across the national airspace system.
