KFC 200-style autopilot controller
The KFC 200's two panel units, each 2 x 1: the mode controller with its six keys (HDG, FD, ALT, NAV, BC, APPR), the DN / UP rocker, AP ON and TEST; and the annunciator panel with its amber legends, the BC lamp, the marker lamps and the red TRIM. The controller drives the simulator's autopilot modes; the annunciators show them.

UNIT > Annunciators
Features
- Mode controller: black box with a thin white line round its face; HDG, FD, ALT, NAV, BC and APPR keys in their white-framed block, each toggling its mode
- AP ON rocker, its top pressed in while the autopilot is engaged; TEST, a small round button
- DN / UP rocker: the vertical trim (the pitch, or the altitude held), stepping while held
- Annunciators: FD, NAV, ARM, ALT, AP / HDG, APPR, CPLD, GS, GA in amber; NAV and APPR show ARM while the needle is beyond two dots and CPLD once captured; GS with the glideslope
- BC lamp, the marker lamps (A white, O blue, M amber) from the simulator, the red TRIM
- TEST (on the controller, seen by the annunciators): everything lit, TRIM flashing, then AP flashing; AP flashes a while when the autopilot lets go
- GA has no simulator counterpart: it lights only in TEST
- Keys sink and click; at night both take the red flood light, the legends keep their amber
On the iPad
- Tap HDG, FD, ALT, NAV, BC or APPR to toggle that mode
- Tap AP ON to engage or disengage the autopilot
- Press the top (DN) or bottom (UP) half of the rocker; hold it to keep stepping
- Tap TEST to run the annunciators' test
Settings
- Unit: Mode controller or Annunciators (picker variant)

Simulator data
What the Hub reads from the simulator for this instrument, and what the instrument sends back. Names are the simulators' own: MSFS SimVars and events, X-Plane datarefs and commands.

Add-on aircraft with their own systems may use other variables; the Hub reads the standard ones.
Changes
The instrument's version counts what its faces share (the case, the mechanism, the data, the sounds); a face's own version counts that face alone.
