Installing a KI 256 is a significant avionics project requiring careful planning, technical skill, and strict adherence to regulations. This guide provides the essential framework, but it is not a substitute for the official installation manual. By following the procedures above and working with a qualified, certified avionics technician, you can ensure the integration of this flight instrument is safe, reliable, and compliant.
Installation of the KI 256 is an integrated process that requires coordination with the aircraft's autopilot computer.
: A highly popular two-axis autopilot system utilizing the KC 295 Flight Computer.
Before installation, verify:
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 has internal shock isolation. Do use additional rubber shock mounts. Mount the tray directly to the instrument panel substructure using #6-32 screws and lock washers. Torque to 8–10 in-lbs.
: After installation, a complete functional test must be performed according to Section VI of the maintenance manual to verify gyro erection, flag behavior, and command bar movement. ki 256 installation manual
