is a critical flight command indicator that integrates a self-contained vertical gyro to provide pilots with essential pitch and roll attitude data. Because it serves as the primary attitude source for various BendixKing Flight Control Systems—including the KFC-150, KFC-200, and KFC-250—following its installation and maintenance protocols is vital for flight safety and autopilot reliability. Core Technical Overview
is designed to be more than a simple display; it is a complex electro-mechanical unit that supplies real-time data to the aircraft's flight computer.
Gyro Functionality: It contains a vertical gyro that drives the horizon mask and provides attitude signals to the autopilot system.
Command Bars: A single-cue command bar displays computed flight director commands, helping the pilot follow the autopilot's intended path.
Panel Compatibility: Units are specifically calibrated for either zero-degree or eight-degree instrument panels to ensure accurate visual alignment during flight. Installation and Modification Protocol Proper handling of the ki 256 installation manual
is mandatory to prevent internal damage and ensure system precision.
Static Protection: All disassembly and assembly must occur at a static-safe workstation. Components removed from the unit should be stored in static-safe bags to prevent electrostatic discharge damage.
Alignment Procedures: 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.
Component Replacement: When updating internal parts, such as the Command Bar Board, technicians must verify that wire connection points match the original layout, though specific pin locations (like E114) may shift between board revisions. Verification and Compliance
After any installation or internal modification, the unit must undergo rigorous validation.
Functional Testing: Technicians must perform a complete functional test as outlined in Section VI of the KI 256 Maintenance Manual to ensure the indicator responds correctly to pitch and roll inputs.
Identification: Completed modifications must be documented by marking the Unit Serial Tag. If space is unavailable, a new Mod Tag must be applied nearby to maintain a clear service history.
Operational Checks: During initial power-up, a distinct "whine" from the gyro's power supply should be audible, indicating the internal motor is spinning up to operational speed.
⚠️ Note: Always consult the most current version of the official BendixKing Downloads & Manuals or professional aviation documentation sites like Scribd before performing any work.

For decades, the King KI 256 has been a cornerstone of the general aviation panel. As the primary attitude indicator for the KCS 55 and KCS 55A compass systems, this 2-inch, remote-mounted vertical gyro provides pitch and roll data to flight instruments and autopilots like the KAP 150 and KFC 200.
However, finding a complete, clear ki 256 installation manual can be a challenge. Honeywell (which acquired Bendix/King) has moved much of this legacy documentation to paid archives. This article serves as a comprehensive technical reference, covering the essential installation data, wiring pinouts, rack mounting, alignment procedures, and post-installation testing derived from the original King manuals.
