70 Installation Manual — Kt
Select a position in the avionics stack away from high-heat sources and heavy magnetic interference (such as compasses).
Ensure a flat, unpainted, conductive aluminum surface area of at least 12 square inches to act as a proper RF ground plane. Coaxial Cable Requirements
Must be interfaced with an encoding altimeter or blind encoder to report pressure altitude in AeroElectric 3. System Interconnects
The KT 70 operates on 13.75 VDC or 27.5 VDC. Ensure the circuit breaker is correctly sized and labeled. Kt 70 Installation Manual
The King KT 70 is a TSO’D Mode S transponder designed to provide air traffic control with aircraft altitude, identification, and surveillance data. Key Specifications
Signal and altitude encoder lines require 22 AWG or 24 AWG wire.
The unit typically includes the top cover, bottom base, and thread-forming screws. Select a position in the avionics stack away
Proper physical placement avoids premature component failure driven by heat dissipation or excessive airframe vibration. 1. Panel Location & Cooling
Secure the KT 70 mounting sleeve to the instrument panel structure using 6-32 flat-head screws. Ensure the rack is rigid and square.
Installation must be performed in accordance with applicable aviation authority regulations (e.g., FAA Advisory Circular AC 43.13-1B and AC 43.13-2A). System Interconnects The KT 70 operates on 13
For runs under 10 feet, RG-400 or RG-142 is recommended. For runs over 10 feet, use low-loss cable like RG-393 or LMR-400 to comply with the maximum allowable signal loss (typically 1.5 dB at 1090 MHz).
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:
Before beginning the installation, proper planning is essential.
The following guidelines should be followed during the installation of the KT 70 system:
