is a core component of many legacy flight control systems, including the KFC-150, KFC-200, KFC 225, and KFC 250. It functions as a self-contained vertical gyro that displays aircraft pitch and roll attitude while supplying these reference signals to the flight computer. Core Technical Specifications

Power Inputs: +14VDC or +28VDC (0.7AMP max); 10VAC at 430Hz (0.2 amp max). Weight: Approximately 3.3 lbs.

Panel Tilt: Available for zero-degree or 8-degree instrument panels.

Display Features: Single cue command bar for flight director pitch and roll commands. Installation & Maintenance Requirements Because the Go to product viewer dialog for this item.

It looks like you’re looking for the KI 256 Installation Manual.

The KI 256 is a King (Honeywell Bendix/King) KI 256 Flight Director Indicator / Attitude Gyro, often used with KFC 150, KAP 150, KFC 200, or KAP 200 autopilot systems.

The official installation manual is typically:

• P/N 006-10593-0000 (or later revisions)
• Title: KI 256 Installation Manual
• Published by Honeywell / Bendix/King

2. Section 2: Installation Considerations

• 2.1 Location: The KI 256 should be mounted in a standard 3-inch instrument panel cutout. It should be located in the pilot's primary field of view, typically to the left or right of the Airspeed Indicator.
• 2.2 Mounting: The instrument must be secured using the provided mounting screws. Ensure the instrument is aligned with the vertical axis of the aircraft.
• 2.3 Lighting (If Applicable): If the unit is the backlit version, verify the aircraft electrical system voltage matches the instrument label. Connect to the dimmer circuit if available.

KI 256 Installation Manual — Quick Installation Guide

Procedure (Abstracted from the Official Manual):

1. Power up the aircraft’s avionics master. Allow gyro spin-up for 3 minutes.
2. Cage the gyro using the front panel push/pull knob (pull to uncage, push to cage). You must cage during installation.
3. Adjust the pitch null – Using a non-metallic screwdriver, adjust R121 (access hole on the rear of the unit) until the pitch reference flag aligns with the index marks.
4. Roll null adjustment – Same procedure, adjust R105 until the roll attitude display reads 0° ±0.25° with the aircraft level.
5. Slip/Skid centering – With the aircraft stationary and level, the slip ball must be centered. If not, mechanically adjust the remote sensor (KG 258) per its manual.

From the field: A common mistake is skipping the 3-minute warm-up. Doing so leads to false nulls and autopilot “porpoising.”
