FEATURES

  • TCAS Computer Unit for the TCAS 2000 system
  • Contains the RF transmitter and receivers necessary to interrogate and receive replies from other transponder equipped aircraft
  • Dual microprocessors utilized to implement the surveillance and collision avoidance algorithms
  • Provides past and present LRU and system status through the front panel mounted TEST switch and PASS/FAIL annunciators 
  • Interface provided for an onboard Mode S transponder in order to communicate with other TCAS ll equipped aircraft
  • Software updates can be incorporated by an ARINC 603 or 615 data loader port through either the connector mounted on the front panel of the computer or the port provided on the LRU rear connector
  • Enhanced ATCRBS Range, Altitude and Bearing Tracker algorithms developed by ACSS provide greater than 99% track probabilities, while reducing false tracks to less than 0.5%

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.
