AC-26-03729 - ASR-8 Weather Kit

The Federal Aviation Administration (FAA) has identified a requirement to procure conversion kits to support modifications to the Air Traffic Control Beacon Interrogator (ATCBI-5) configuration at Airport Surveillance Radar Model 8 (ASR-8) facilities as part of the Brand-New Air Traffic Control System (BNATCS) implementation under the Radar System Replacement (RSR) Program.
The rotary joints currently installed at ASR-8/ATCBI-5 sites do not provide the number of signal paths required to support integration with the RSR architecture. To achieve compatibility, the existing rotary joints must be converted to the configuration utilized at ASR-8 sites equipped with the Mode Select Beacon System (Mode-S). This conversion requires the installation of a kit developed by AJW-1433, which adds an additional signal path to accommodate Weather Signal transmission through the rotary joint.
