Per the installation manual:

However, finding a complete, clear 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.

: Operates on 14/28 VDC (approx. 0.7 AMP max) and 10 VAC, 430Hz (0.2 AMP max). Dimensions : Approximately 3.55" W x 3.37" H x 7.31" L. Weight : Approximately 3.3 lbs. ki 256 installation manual

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.

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 Per the installation manual: However, finding a complete,

The KI 256 is a 3-inch panel-mounted attitude indicator designed for use with the KCS 55/55A Slaved Compass System. It displays pitch (±85°) and roll (360°) via a internally gyro-stabilized sphere. The unit requires DC power and a remote gyro amplifier (KA 51B, KA 51C, or KC 235).

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. : Operates on 14/28 VDC (approx

The BendixKing KI 256 is a critical vacuum-driven used extensively in legacy flight control systems like the KFC 150, KFC 200, and KFC 225. It serves a dual role: providing a visual attitude display for the pilot and supplying pitch and roll attitude data to the autopilot computer.

Rear-mount configuration via four standard panel screws. Electrical Power

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
