The low range altimeter (LRA) is a landing radio altimeter that measures the distance from the aircraft to the ground during approach and landing phases of your flights. The LRA-900 delivers extremely high altitude accuracy. It includes enhancements to a digitally-controlled variable bandwidth filter which offers improved noise rejection and leading-edge tracking. It also features digital technology and proven frequency-modulated continuous-wave techniques.
In addition, the LRA-900 is designed to fulfill all new environmental requirements. The system has protection for Category K lightning and Category Y high-intensity radiated fields (HIRF). And it’s fully functional through 200 milliseconds of power interruptions.
