Kt 70 Installation Manual
The performance of the Mode S system depends heavily on a low-loss RF path. Antenna Placement
: The altitude readouts on the KT 70’s display must be explicitly cross-checked against the primary cockpit altimeter to verify flawless parallel Gray code transmission. Modern Regulatory Notice: ADS-B Out Compliance
Forced air cooling is highly recommended for longevity.
The KLORTNER KT-70 is a pinless meter that uses a microprocessor for signal processing. Its key features, which are explained in detail in the manual, are: Kt 70 Installation Manual
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
requires precise wiring for power, ground, and altitude encoding.
Proper installation requires a dedicated mounting rack and specialized connectors. Mechanical Installation The performance of the Mode S system depends
The performance of the transponder system is highly dependent on the integrity of the RF antenna and the specifications of the coaxial cabling. Antenna Placement Considerations
Use a transponder ramp tester (e.g., IFR4000) to confirm mode S replies and power output. 6.0 Post-Installation (Flight Check)
There’s no separate one-page “do this first” section. You have to read all safety warnings (important, but repetitive) before reaching the actual steps. A seasoned installer might skip ahead and miss critical grounding instructions. The KLORTNER KT-70 is a pinless meter that
Place the mounting tray in the instrument panel stack. Ensure it is perfectly level so the unit engages smoothly with the rear connectors.
Do not use a generic or all-zeros address code. Flying with an unprogrammed or incorrectly programmed Mode S address is a regulatory violation and disrupts ATC tracking. Ground Testing Checks
Turn on the avionics master. Verify that the KT 70 powers up, displays its self-test sequence, and does not trip the circuit breaker. Check that the display dimming responds correctly to the aircraft panel lighting bus.
