066-01127-1602 – Honeywell TRA 67A Mode S Transponder
Available now on the Airparts.aero Marketplace.
Overview
The Honeywell TRA 67A, part number 066-01127-1602, is a full-featured Mode S digital transponder designed for the demanding operational environment of transport category and high-performance business aircraft. This transponder is a cornerstone of modern avionics, providing the critical link between the aircraft and the global air traffic control (ATC) system. It is engineered to meet the stringent requirements for TCAS II (Traffic Collision Avoidance System) integration and is a key component for worldwide ADS-B Out compliance. The TRA 67A provides robust, reliable performance, ensuring seamless data communication with both ground-based radar and other Mode S equipped aircraft.
Key Features
- Mode S with Enhanced Surveillance (EHS): The TRA 67A goes beyond basic Mode S capabilities by supporting Enhanced Surveillance. This allows the transponder to automatically downlink a rich set of aircraft-derived parameters (DAPs)—such as indicated airspeed, Mach number, selected altitude, and roll angle—providing ATC with superior situational awareness and enabling more advanced air traffic management.
- TCAS II Integration: Designed to work as an integral part of a TCAS II system (like the Honeywell TPA-100 or CAS-67A). The Mode S datalink is essential for the coordination between aircraft to issue Traffic Advisories (TAs) and life-saving Resolution Advisories (RAs).
- ADS-B Out Foundation (1090ES): Serves as the high-integrity broadcast platform for ADS-B Out. When paired with a certified GPS position source, the TRA 67A broadcasts the required "extended squitter" messages on the 1090 MHz frequency, providing precise position, velocity, and status information to ATC and other aircraft.
- Full Diversity Operation: Utilizes both top and bottom directional antennas to ensure reliable, 360-degree signal transmission and reception, eliminating airframe "shadowing" and guaranteeing continuous contact with ATC and TCAS interrogators.
- ARINC 718 Compliant: Built to the ARINC 718 standard for ATCRBS/Mode S transponders, ensuring standardized form, fit, and function for seamless integration into a wide range of aircraft avionics racks.

Applications
The TRA 67A is a flight-critical component at the center of aircraft surveillance and safety:
- Air Traffic Control Surveillance: Provides the primary means for ATC to identify and track the aircraft using both traditional Secondary Surveillance Radar (SSR) and advanced Mode S selective interrogation.
- Collision Avoidance: The essential datalink component for TCAS II, enabling aircraft-to-aircraft communication to deconflict traffic and prevent mid-air collisions.
- ADS-B Out Mandate Compliance: The core transponder required to meet FAA, EASA, and other global mandates for Automatic Dependent Surveillance-Broadcast.

The Honeywell TRA 67A's support for Mode S Enhanced Surveillance (EHS) is a key technological feature. While standard Mode S provides basic flight data, EHS allows for the downlinking of a much richer data set directly from the aircraft's flight data computer. This gives ground-based ATC systems a more complete picture of the aircraft's intent and current state without relying solely on radar tracking updates. This improved data quality enables more efficient routing, reduced separation minima in certain airspaces, and enhanced safety monitoring tools for air traffic controllers. The TRA 67A acts as the secure, high-integrity radio gateway that makes this advanced level of air-ground data integration possible.
Note: This is a flight-critical avionics component. Installation, configuration, and testing must be performed by a certified Part 145 repair station or a qualified avionics technician in strict accordance with the manufacturer's installation manual and all applicable airworthiness regulations. Proper configuration of the ICAO 24-bit aircraft address is mandatory.
