The manual covers the physical and electrical integration of the KT 70 into an aircraft's avionics stack. Target Device: BendixKing KT 70 Mode S Transponder.
Ensure the altitude transmitted matches the primary pilot altimeter within 6. Troubleshooting Common Installation Errors
Once the unit is mechanically and electrically secured, several checkout procedures are required to ensure compliance with aviation regulations. BendixKing KT-70 | SEAEROSPACE.COM
Guides the installer through programmable features, such as display brightness levels and dimming times. Testing & Alignment: Kt 70 Installation Manual
– Solid, not stellar. Gets the job done, but leaves room for improvement in visual design and beginner support.
By jumping specific configuration pins or utilizing a designated key sequence on the front panel during power-up, the unit enters its programming configuration menu. Technicians must define:
: Although the KT 70 utilizes solid-state technology, its 35W maximum draw generates modest thermal loads. Ensure adequate ventilation workspace behind the tray; forced-air cooling is highly recommended for tightly packed radio stacks. The manual covers the physical and electrical integration
(Note: Sections 1–3 are often relocated to the separate Installation Manual).
For sensor-based models (e.g., thermocouple or RTD input), the calibration steps assume you have a known reference source. The manual doesn’t explain how to simulate a sensor signal without extra equipment – leaving DIY users stuck.
Access the maintenance menu to set the aircraft address (hex code), flight ID, and altitude encoder type. Ground Test: Apply power and check for error messages. Verify the unit displays the correct altitude. Troubleshooting Common Installation Errors Once the unit is
A flawless installation relies entirely on the precision of the wire harness. The installation manual provides complete schematics detailing the specific pinout assignments on the rear connector block.
Use RG-58 or RG-142 coaxial cable to minimize signal loss.
Includes detailed dimensions for the mounting tray and location considerations, such as antenna placement relative to the engine and landing gear to ensure a clear ground plane. Electrical Wiring:
To transmit Mode C or Mode S altitude data, the transponder must receive a valid signal from an altitude encoder or air data computer. The manual outlines two primary methods for this:
Install the unit in a cool, dry area, typically in the avionics stack. Installation Procedure:
