In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.

Yes, there is an adapter available to upgrade to the new ART-2100. Please see Southeast Aerospace's upgrade solution - (ART-2100 Upgrade flyer)

The ART-2100 will replace the RS-861A with the incorporation of an adapter harness prescribed in Honeywell Installation Bulletin No. 445. The original IN-862A indicator (-00,01,30,31) are functional indicators that can be used with the ART-2100 sensor. The CM-2000 configuration module would need to be added in the radar system as well.

Southeast Aerospace provides complete retrofit packages for the Bendix RS series radar sensors to Honeywell ART sensors. Packages include equipment, adapter harness, programmed configuration module, and other instructions. Please contact Sales Dept for an exact quote.

The Bendix/King RDR 2100 Installation Manual (006-00648-0002), on page 1-1 states: "The RDR 2100 System consists of four modules: the Antenna/Receiver/ Transmitter (ART), the Radar Indicator, the System Antenna, and the Configuration Module. The system is positioned as a replacement for the RDS 86 ART."

In addition, there is a "RS-861A to ART-2100 Harness Connector Replacement" diagram in the RDR 2100 Installation Manual on page 2-107, Figure 2-50.
