Ki 256 Installation Manual Work Jun 2026

After installation, comprehensive testing is required to verify the system's accuracy.

For systems like the KFC 200 , a full system alignment may be required during installation. This involves using specialized tools like a regulated 4.5 in. Hg. air source and connecting the gyro to the airplane harness via an extender cable to verify operation.

Before removing the KI‑256, verify that the replacement is approved under an STC for your specific autopilot model, and that the backup flight director display requirements are satisfied.

The Bendix/King KI‑256 Flight Command Indicator (FCI) is a highly respected attitude reference instrument that has served as the visual “heart” of many Bendix/King autopilot/flight director systems for decades. Installed in thousands of business and general‑aviation aircraft—including the KFC‑150, KFC‑200, KFC‑225, and KFC‑250 flight control systems—the KI‑256 combines a self‑contained vertical gyro with a single‑cue flight‑director command bar to present both aircraft pitch/roll attitude and computer‑generated steering commands in one compact unit.

The BendixKing KI 256 Flight Command Indicator (FCI) installation manual is a technical document that outlines the integration and setup of this self-contained vertical gyro into BendixKing flight control systems like the KFC-150, KFC-200, KFC-225, and KFC-250 Bendix/King Key Technical Aspects System Integration:

: Requires a regulated 4.5 in. Hg air source; proper filtration and regulation are critical for gyro operation. Installation & Maintenance Procedures Rear-mount configuration via four standard panel screws

: Post-installation, a functional test must be performed. Testing often involves specialized equipment like the KTS 150 Flight Control System Test Set .

is mandatory to prevent internal damage and ensure system precision.

: A highly popular two-axis autopilot system utilizing the KC 295 Flight Computer. a functional test must be performed.

Given the lack of specifics about "ki 256," the above is a generic guide. For accurate and detailed instructions, it's best to consult the official documentation or contact the manufacturer directly.

Use MIL-W-22759/16 wire. Shielded twisted pairs must be used for the 26VAC 400Hz excitation lines and the pitch/roll analog outputs to prevent EMI (electromagnetic interference) from leaking into the audio panel or GPS lines.
