RDR-4B
RDR-4B was operating in X-band airborne navigation and weather radar with forward-looking windshear detection. Two antenna sizes were available. Honeywell introduced later the first weather radar featuring an automatic antenna tilt computation named “Autotilt”.
The radar was certified by the Federal Aviation Administration (FAA) in 1995. Over 6 000 units were in service worldwide. The successor was the RDR 4000 from Honeywell.
