KFC 225 Autopilot 

Pilot Handbook 

 

- 25 – 

For use with Microsoft Flight Simulator only. Not to be used in real world aviation. 

3. Terminology 

 

AP Master Key

 

 

Fig. 1a, #2. Toggles between Active and Standby modes. Autopilot will 

only control the aircraft in Active Mode. Key will illuminate when in 

Active Mode. 

 

Active Mode

 

Indicates that the autopilot is in control of the aircraft's control surfaces, either by 

control servos (Servo Control Modes) or by trim control motors (Fixed Trim Modes). 

 

 

Altitude Preselect Mode 

Aircraft is configured to seek and maintain a preselected (indicated) altitude, in 

feet. 

 

 

AP Servo Annunciator 

  Annunciator that illuminates when one of the Servo Control Modes is 

active. 

 

Back Course 

A runway approach where the HSI needle is set to the outbound rather than the 

inbound track, for the aircraft to fly in the opposite direction of the runway. 

CDI Indicator 

Course Deviation Indicator - an avionics instrument used in aircraft navigation to 

determine an aircraft's lateral position in relation to a track. If the location of the 

aircraft is to the left of course, the needle deflects to the right, and vice versa. 

Control Center 

Utility for configuring your FlightSim Developers Bendix King radios and autopilot in 

your specific Flight Simulator panels. You can find it within your Flight Simulator 

directory structure in the folder: 

FlightSim Developers\Bendix King\Control Center.exe 

Course Mode 

Servo Controlled Mode for the autopilot roll axis. Sets a microprocessor defined 

course heading, determined by the HSI/Gyro heading bug, in HDG Mode, or by data 

input from the NAV radio in NAV, APR or REV modes. 

Dutch Roll 

A type of aircraft motion, consisting of an out-of-phase combination of "tail-

wagging" and rocking from side to side. This yaw-roll is an indication of poor 

directional stability, introducing a sideslip into the relative wind in the direction of 

the rolling motion. Dutch Roll can be excited by any use of aileron or rudder. 

Fixed Trim Modes

 

Autopilot will configure the aircraft in a Roll Mode and/or pitch, until instructed 

otherwise. 

Front Course 

A runway approach where the HSI needle is set to the inbound track (runway 

heading) for aircraft final approach 

Omnibearing Selector (OBS) 

A device capable of being set manually to any desired omnibearing, or its 

reciprocal, to control a course-line deviation indicator. Also known as radial selector. 

 

 

Roll Axis

 

Aileron and rudder control. Rotation along the longitudinal axis (nose to tail) of the 

aircraft. 

Roll Axis Function Keys 

Keys used in Course 

Mode: 

 

 

Roll Mode

 

Autopilot is configured to maintain a fixed roll, in degrees, until instructed 

otherwise. 

 

 

Servo Control Modes 

Autopilot will configure the aircraft in Course Mode and/or Altitude Preselect Mode. 

Standby Mode

 

Allows change of settings and control parameters, but the autopilot will take no 

action until the AP Master Key is pressed ON.
