Installation Manual - Kt 70
The KT 70 should be mounted in the radio stack within clear view of the pilot. While it features highly efficient solid-state circuitry, stacking multiple pieces of avionics creates tight thermal pockets. The manual emphasizes checking for or ensuring adequate passive airflow spacing to protect the internal power supply components. 2. Mounting Rack Deployment
The Bendix/King KT 70 Installation Manual (Part Number 006-00673-0002) is a technical publication that provides the essential engineering data and procedural instructions required to certify and install the KT 70 Mode S transponder into an aircraft's avionics suite. As the first panel-mounted Mode S transponder, the KT 70's installation manual serves as the bridge between advanced surveillance technology and practical airframe integration. Technical Specifications & Requirements
Connect the transponder to a dedicated circuit breaker ( Altitude Encoding: The Kt 70 Installation Manual
Only after confirming correct sensor reading, wire the load through the output device (SSR or contactor).
: Certified to function at pressure altitudes up to 50,000 feet within a temperature envelope of -20°C to +55°C . The KT 70 should be mounted in the
Ensure the antenna is mounted vertically down when the aircraft is in a normal cruise attitude.
Mounting on the fuselage exterior with specific separation distances from other avionics, such as DME or VHF antennas, to avoid electromagnetic interference. such as DME or VHF antennas
