The LRA-2100 is the first Collins Aerospace digital radio altimeter replacing legacy analog-based radio altimeters.

The LRA-2100 is used to provide extremely high altitude accuracy above terrain during approach and landing phases of flight. Accurate altitude information during approach and landing phases is crucial to autopilot and auto-landing systems that require high integrity accurate altitude information. The data is also a critical input to the Terrain Awareness and Warning System.

The LRA-2100 benefits from digital technology to provide 40% less power and 25% less weight. The latest digital technology eliminates legacy analog components and utilizes dual independent processing of all return components in range returns simultaneously. This enhanced capability for altitude reporting enables multi-target adaptation for fewer auto-pilot disconnects, bright spot rejection, and rejection of under-flying aircraft. This technology provides significantly improved performance over runway approach structures to better ensure integrity and safety.
