NASA Modernizes Commercial Airline Systems

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s researchers know that when you settle into your seat on a commercial flight, you expect a smooth takeoff, views over the clouds, a steady descent, and hopefully an early arrival at your destination. But when your flight gets delayed on the tarmac instead of lifting off, or it ends up in a holding pattern rather than landing on time, things start to change. Your experience goes from smooth to anxiety-inducing as you worry about making your connection or getting home in time for dinner.
Large airports are among the busiest, most complex environments in aviation, with aircraft, ground crews, and service vehicles sharing crowded taxiways. Researchers at NASA’s Ames Research Center in California’s Silicon Valley recently worked with Boeing to advance three types of field tests – digital taxi information, safe taxiway, and safe runways – that could lead to safer, more efficient runway environments at airports.
During the digital taxi tests, pilots were given taxiway guidance directly on cockpit displays or tablets, instead of verbally from air traffic controllers. Aircraft autonomously followed digital routes while researchers monitored a suite of sensors designed to identify vehicles or other aircraft impeding the taxi path and runway. The system reduced pilot and air traffic controller workloads and the risk of verbal errors.
Safe runway technology testing can also improve situational awareness for approaching aircraft. While preparing to land a Boeing aircraft during testing, the same sensors successfully flagged a vehicle on the runway, providing additional awareness to ensure pilots could avoid potential collisions or other safety concerns.
Together, these NASA capabilities aim to reduce miscommunication, ease pilot workloads, and keep airport traffic moving smoothly. Future testing will integrate the sensor and digital taxi systems into a simulated air traffic control environment to evaluate how the technologies can benefit overall management of the airspace.
For years, NASA has worked to improve your experience when flying by developing new technologies to modernize the commercial airline system. Key NASA technologies streamline and digitize the flying experience – from the departure gate, to the skies, to your safe arrival at your destination.
“Aviation safety is key to NASA’s research,” said Parimal Kopardekar, director of NASA’s Airspace Operations and Safety project. “Technology that can provide additional autonomy and support a future airspace with multiple aircraft operating in harmony is key to advancing the National Airspace System.”
NASA’s research innovations continue after your flight takes off. Modern flights constantly respond to shifting weather, turbulence, and traffic. Even small changes in direction or altitude can affect when a plane arrives. These changes can force flights into holding patterns while air traffic controllers attempt to rebalance the busy airspace.
NASA’s air traffic management researchers have been working for years to reduce those situations. In a 2025 collaborative effort with Boeing, United Airlines, and international partners, NASA evaluated real‑time trajectory sharing on domestic and transoceanic flights.
During that testing, a United Airlines Boeing 737 aircraft shared frequent flight information with airline operations centers and air traffic control. NASA used the data to understand how frequently those updates should be sent and what details matter most for generating accurate arrival predictions. Better information helps controllers sequence traffic more precisely, which means fewer holding patterns and more direct descents for passengers.
Pre-departure rerouting technology and digital exchange tools developed at NASA allow dispatchers and controllers to see the same digital picture of flights preparing to depart.
When a better route becomes available, controllers could coordinate the change digitally instead of relying on verbal communication between pilots, controllers, and dispatchers. The technology could lead to fewer delays, reduced fuel consumption, and more predictable operations for passengers.
NASA has now transferred the routing technology to the Federal Aviation Administration (FAA) and airlines will continue to test it. These tools build on decades of NASA contributions to national airspace modernization.
In coordination with the FAA, NASA has advanced automation concepts, improved how arrival and departure flows are managed, and introduced data‑driven software that commercial airlines use every day.
By working closely with airlines, manufacturers, and global partners, NASA is helping to improve every phase of flight to make air travel safer and more reliable, now and in the future.
