Big Capability in a Small Package

ACSS offers this full-featured ICAO Level 3 Mode S diversity transponder in a small, lightweight package optimized for regional, corporate aircraft and helicopters. The RCZ-852 is a stand-alone implementation of the Mode S technology integrated into the radio suite currently flying on more than 2,500 regional and business aircraft.

The RCZ-852 is designed to meet environmental requirements of unpressurized aircraft to 55,000 feet, with vibration profiles that meet the requirements for turbojets, fixed wing propeller aircraft and helicopters. When compared with ARINC Mode S transponders, the RCZ-852 is smaller, lighter and requires less power. The RCZ-852 is designed for compatibility with all currently available TCAS I and TCAS II systems.

The RCZ-852 Mode S transponder has been designed for reliable performance and ease of maintenance. Highly Accelerated Life Testing (HALT) was performed on all engineering models of the RCZ-852. Each production RCZ-852 unit is subjected to Highly Accelerated Stress Screening (HASS) before being shipped to customers to ensure the highest product quality.

High dependability of our Mode S transponder greatly enhances the overall TCAS system reliability by reducing Mode S transponder-induced TCAS no-fault-found failures. Extensive BIT (Built-In Test) ensures that approximately 90 percent of the circuitry is tested during system operation.

The RCZ-852 Mode S Transponder is easily upgradeable for tomorrow's technology requirements. It has all of the required functionality for ICAO ACAS II mandate compliance, European Elementary and Enhanced Mode S Surveillance Downlink of Aircraft Parameters (DAPs), and ADS-B 1090ES extended squitter, as defined in the Aeronautical Information Circulars (AICs) and ICAO SARPS.
