Charlotte Douglas just started construction on a 4th parallel ‘smart’ runway to both increase capacity and test out a new ‘digital twin’ technology in partnership with UNC Charlotte through its Aviation and Innovation Research Institute.
Sensors will be installed as concrete is poured on the new runway, located between existing runways 2 and 3. These instruments will track how pavement responds to aircraft traffic, weather, and long-term wear.
The data will feed into a digital twin, or virtual replica, of the runway. Engineers will use it to test scenarios, identify stress points, and predict maintenance needs before problems develop.
“By embedding technology directly into the runway, we aren’t just building infrastructure,” said UNCC Vice Chancellor John Daniels in a press release. “We are creating valuable data, models and insights that will inform the future of airfield design nationwide. Just as important, this work creates unparalleled, hands-on research opportunities for our students, who will be learning under the leadership of Dr. Cavalline.”
Airport officials say the technology will improve safety and efficiency. It could also guide daily operations, including de-icing and maintenance decisions.
The project stems from the airport’s 2016 Master Plan as Charlotte continues to grow. In 2025 alone, CLT recorded more than 574,000 aircraft operations, ranking seventh worldwide.
The digital twin portion of the project will cost about $6.5 million, including a $2 million grant from the Federal Aviation Administration.
Once complete, the 10,000-foot runway will include upgraded electrical systems, improved drainage, and a new fire station. The runway is expected to open in fall 2027.
