Collins Aerospace, a unit of RTX, says it is upgrading radio altimeters to align with new FAA requirements

RTX’s Collins Aerospace said it is rolling out upgrades to its family of radio altimeters, positioning the updates as a way for business aviation operators to comply with new Federal Aviation Administration standards. The announcement, published Oct. 21, frames the work as a compliance pathway rather than a new product launch, and it targets aircraft already equipped with radio altimeter systems.

Radio altimeters are aviation instruments that determine an aircraft’s height above the ground using radio indicates. They are used to support approaches and landings, especially in conditions where pilots need accurate altitude information close to the runway. Collins did not specify in the announcement which radio altimeter configurations are covered, but it characterized the upgrade effort as applying across a “family” of units.

In its statement, Collins Aerospace said the upgrades are designed to help operators meet “new FAA standards.” The company did not outline what those FAA standards require in technical terms, such as the targeted measurement performance, approval pathway, or any associated installation rules. It also did not name specific aircraft types or show a list of eligible avionics configurations.

Because radio altimeters often sit within an aircraft’s broader avionics and flight deck systems, compliance changes can have ripple effects for operators. Upgrades may require engineering work to integrate revised software or hardware, plus coordination with avionics shops and aircraft maintenance programs. Collins did not provide guidance on expected lead times or the operational impact for customers, such as whether the upgrades are intended for line replaceable units, retrofit kits, or scheduled maintenance events.

Industry-wide, FAA standard changes can influence procurement planning and retrofit decisions. For business aviation operators, the practical challenge is aligning aircraft maintenance windows with certification and availability of compliant equipment, while ensuring that avionics performance remains consistent with flight operations requirements. Collins’ message suggests it wants to reduce that uncertainty by offering a clear route to compliance, but it stops short of providing operational specifics.

The company’s announcement did not disclose the depth of the modifications, the certification status of the upgrades, or which regulatory documentation supports the new FAA-alignment claim. It also did not say whether the updates require changes beyond the altimeter itself, such as related sensors, system wiring, or display/interface software within the cockpit. Those missing details are important for operators evaluating what it would take to certify and install the upgrades on particular fleets.

Looking ahead, the key information to watch is whether Collins or RTX publishes additional technical details after the initial announcement, including the exact FAA requirements addressed, the certification milestones for the upgraded altimeter configurations, and any customer-ready timelines. Operators will likely also look for clear eligibility guidance, such as which aircraft and avionics configurations are supported and what integration or maintenance steps are required.
