RTX (NYSE: RTX) announced Collins Aerospace radio altimeter upgrades designed to help business aviation operators meet new FAA operational standards. The upgrades apply to existing variants and have demonstrated resilience to 5G interference without requiring replacement of existing systems.

Collins service centers will begin providing upgrades in 2027 as part of a multi-year compliance effort. Radio altimeters measure aircraft height above terrain and support flight controls, cockpit displays and warning systems. With tens of thousands of aircraft requiring updates, Collins recommends early scheduling to help operators avoid delays and meet upcoming deadlines.

"upgrades for its family of radio altimeters"
A radio altimeter is an aircraft instrument that measures the airplane's height above the ground directly beneath it by sending radio waves downward and timing the return signal; the time delay (or frequency shift) is converted into an altitude reading. It provides accurate low‑altitude height-above-terrain information used for landing systems, autopilot functions, and terrain-avoidance warnings, and it differs from barometric altitude (which references sea level). Its readings are reliable only within the device's operational altitude range and can be degraded by signal reflection, interference, or unusual ground surfaces.

Upgrades strengthen aircraft resilience as aviation adapts to increased wireless spectrum use

LAS VEGAS, Oct. 21, 2026 /PRNewswire/ -- Collins Aerospace, an RTX (NYSE: RTX) business, today announced upgrades for its family of radio altimeters, providing business aviation operators a clear path to meet new Federal Aviation Administration (FAA) operational standards.

Collins is providing simplified upgrade paths to its existing radio altimeter variants that meet the new FAA requirements and have demonstrated resilience to 5G interference without the need to replace existing systems.

"Business aviation operators are navigating important regulatory requirements that touch every aircraft flying in U.S. airspace," said Craig Bries, vice president and general manager of Airborne Electronics at Collins Aerospace. "By updating existing equipment, we're making compliance simple while delivering upgrades that enhance safety, strengthen connectivity and support precise navigation in the years ahead."

Collins' radio altimeters are engineered to provide precise, reliable measurements of an aircraft's height above terrain, supporting critical functionality such as automatic flight control, cockpit instrument displays and warning systems. The systems are designed to filter out false altitude returns caused by structures, nearby aircraft or ground features, helping maintain consistent situational awareness during critical stages of flight.

Collins service centers will begin providing upgrades in 2027, as part of a multi-year effort to bring business aviation fleets into compliance with the new standards. Because tens of thousands of aircraft will require updates, early scheduling will help operators avoid delays and ensure they meet upcoming deadlines.

Collins' radio altimeter upgrades are part of the company's broader airspace modernization efforts, introducing new capabilities while strengthening the proven systems on which airspace users and managers depend. This includes avionics that support increasingly capable operations and technologies that connect aircraft, controllers, infrastructure and data. Together, these efforts are designed to make aviation more resilient, connected and capable as traffic, technology and operational demands grow.
