The BendixKing KI 256 serves as a critical attitude and flight command indicator, requiring strict adherence to engineering standards for installation and integration with legacy autopilots. Key procedures include implementing Service Bulletin 11 for modified command bar boards and precise pneumatic calibration at 4.5 in. Hg. Detailed installation, modification, and maintenance, including Service Bulletin 11, can be found in the documentation provided by peter2000.co.uk KI 256 Flight Command Indicator

The electrical connections on the back of the KI 256 bridge the pneumatic unit to the digital or analog flight computer (such as the KC 295 or KC 192). Interfacing relies heavily on standard MIL-spec shielded wire to prevent RF interference from radiating into sensitive attitude loops.

The KI 256 is a 3-inch (ATI) panel-mounted electrically driven attitude gyro with built-in Flight Director command bars. It receives pitch and roll steering commands from an external Flight Director computer (e.g., KFC 150/200/250 series). The instrument requires both (or optional 14 VDC with converter) and a regulated vacuum source for gyro spin-up and rigidity.

The KI 256 is a sophisticated instrument designed for precise measurement and indication of various parameters. This report provides a comprehensive overview of the installation procedures for the KI 256, ensuring a successful and efficient setup.

The removal and installation of the KI 256 follow standard procedures for face-mounted instruments: Pre-Installation and Unpacking Leave a service loop of

The KI 256 is designed to fit standard aircraft instrument panels and is available in configurations for both zero-degree and eight-degree panel tilts.

As of 2025, the KI 256 is considered . Honeywell no longer manufactures new units, and repair costs (typically $1,500-$2,500) often exceed the value of the gyro. However, for vintage Beechcraft Barons, Cessna 340s, and Piper Navajos, keeping the KI 256 running is still common.

Maintenance procedures often involve specific Service Bulletins (SB), most notably SB KI 256-11
