is a critical flight instrument, installation must be performed by an FAA-approved mechanic .
The KI‑256 is available in two primary mounting configurations:
Advanced analog and digital legacy systems requiring valid gyro reference voltage. Technical Specifications Overview

The KI‑256 requires an uninterrupted supply of filtered, regulated vacuum (or pressure) to spin its gyro rotor to between .
Disconnect the aircraft battery before handling any electrical wiring.
Electrical items, including the KI 256, must be installed by a licensed repairman or installer to be eligible for any return policies. Always disconnect the aircraft’s battery before working on any electrical connection. is a critical flight instrument, installation must be
Standard avionics hand tools (wire strippers, crimpers, pin extractors). Vacuum/Pressure gauge calibrated for aircraft systems.
Once the KI‑256 is physically installed and wired, the real work begins: integrating it with the autopilot/flight director computer and calibrating the pitch/roll pick‑off signals.
Insert the KI 256 from behind the panel and secure it using standard 6-32 brass or non-magnetic screws to prevent interference with nearby magnetic compasses. 3. Electrical Wiring and Pinout Configuration The KI‑256 requires an uninterrupted supply of filtered,
The dedicates five pages to wiring. Below is the essential pinout for a standard KFC 150 autopilot integration. Always verify against your specific serial number.
Use spring bands or approved zip-ties to secure connections. Avoid over-tightening plastic fittings, which can crack and cause vacuum leaks. 5. Post-Installation Alignment and Calibration
The KI‑256 contains LVDT‑type pick‑off coils that produce AC signals proportional to pitch and roll. These signals must be aligned with the autopilot computer’s expectations. This calibration requires a or an approved equivalent.
Tighten the rear locking mechanism or front-mounting screws until secure. Do not overtighten. 3. Electrical Wiring and Pin Connections
Receives steering commands from the computer to drive the single-cue command bars.
