karim b05ffedbc1 Citation X cockpit profile: full Primus 2000 suite (PFD/MFD/EICAS/AP/RMU)
Add a switchable cockpit-profile selector (Garmin G1000 / Cessna Citation X /
GA steam) and recreate the Citation X Honeywell Primus 2000 avionics line-for-
line from the X-Plane Citation X + FMS manuals:

- CitPFD: attitude w/ FD command bars, speed tape (Vmo barber-pole, Vfe, low-
  speed red/amber bands), AOA index, altitude tape + trend, VSI, round HSI with
  CDI/course pointer + VOR/ADF bearing pointers, radar altimeter, minimums,
  STD/BARO/CRS/HDG bezel.
- CitEICAS: twin FAN%/ITT bar gauges, OIL °C/PSI, FUEL (flow/qty PPH·LBS),
  ELECTRICAL, HYDRAULICS, slat chevron, STAB trim, FLAPS, CAS message stack,
  softkeys NORM/FUEL-HYD/ELEC/CTRL-POS/ENG + control-position overlay.
- CitMFD: Honeywell heading-up arc map, FMS route (magenta active/white future),
  TCAS, terrain/WX, range arc, ETE/SAT/TAS/GSPD block, clock + ET/FT timer,
  V-SPEEDS reference card, MFD-setup overlays (TRAFFIC/TERRAIN/APTS/VOR).
- CitAP: HDG/NAV/APP/BC · ALT/VNAV/BANK/STBY · FLC/C-O/VS · pitch wheel ·
  AP/YD/M-TRIM/PFD-SEL, FMA bar + lamps from per-mode *_status datarefs.
- CitRMU: COM/NAV active+standby tuning, transponder, ADF, TCAS range/mode,
  IDENT + Nav Source Selector (NAV1/2/FMS, VOR/ADF/FMS bearing source).

Integration: all avionics stream live via the X-Plane Web API (new datarefs for
N1/N2/ITT, radar-alt, AOA, hydraulics, trim, flaps/slats/gear, control
positions, ADF, mach, yaw-damper); the existing fms-sync.lua drives the
Citation's built-in FMS (aircraft-agnostic XPLM FMS SDK). Demo seeds added so
every panel renders offline. Verified headless via Playwright (no console
errors; G1000/GA profiles unaffected).

FlyWithLua companion — FMS two-way sync

X-Plane's Web API can't write a flight plan into the FMS. fms-sync.lua runs inside X-Plane (via FlyWithLua, which has the FMS SDK) and syncs the shared cockpit plan ↔ the in-sim FMS through two files in Output/fms-sync/.

Install (sim PC only)

  1. Install FlyWithLua NG+ (free): copy its plugin folder into <X-Plane>/Resources/plugins/FlyWithLua/.
  2. Start the bridge (desktop app or node server/bridge.js) on the same PC as X-Plane. On startup it auto-copies these three scripts into <X-Plane>/Resources/plugins/FlyWithLua/Scripts/ and keeps them up to date on every launch (it only writes changed/missing files):
    • fms-sync.lua — flight-plan two-way sync
    • ui-sync.lua — G1000 UI state (page / range / inset)
    • terrain-probe.lua — terrain-awareness elevation grid for the MFD
  3. In X-Plane: FlyWithLua → Reload all Lua script files (or restart). The log shows [glass-cockpit] FMS sync active.

No manual copying needed. If you install FlyWithLua after the bridge is already running, trigger a re-install without restarting via POST /api/lua/install. The current install state is reported under lua in GET /api/health. The bridge must run on the same PC as X-Plane so both see <X-Plane>/Output/fms-sync/. (The auto-install honours LUA_SRC_DIR — the desktop app sets it to the bundled scripts; otherwise it finds plugins/ itself.)

What you get

  • App → Sim: load/build a plan in the web cockpit → it appears in the 3-D G1000 and the autopilot can fly it.
  • Sim → App: build/edit the plan in the real FMS → it shows on every tablet.
  • Terrain: the MFD TERRAIN map colours real scenery elevation red/yellow relative to your altitude (probed live by terrain-probe.lua).

A 3-decimal lat/lon signature de-dupes the round-trip, so the two sides never loop. Waypoints are pushed as lat/lon legs (exact route; in-sim idents are generic — route accuracy over cosmetics).

Cessna Citation X (Honeywell Primus 2000)

The app ships three switchable cockpit profiles (sidebar dropdown): the Garmin G1000, the Citation X, and a GA steam panel. The Citation profile recreates the Primus 2000 suite line-for-line from the X-Plane Citation X manual — PFD (attitude, speed/alt tapes with Vmo barber-pole + Vfe + AOA, HSI with VOR/ADF bearing pointers, CDI, VSI, FD bars, radar altimeter, minimums), MFD (Honeywell arc map, FMS route, TCAS, terrain/WX, ETE/SAT/TAS/ GSPD, ET/FT timer, V-SPEEDS card), EICAS (twin N1/ITT/oil, fuel, electrical, hydraulics, slats, stab-trim, flaps, CAS), the autopilot/flight-guidance controller (HDG/NAV/APP/BC · ALT/VNAV/BANK/STBY · FLC/VS · AP/YD/M-TRIM/PFD-SEL

  • pitch wheel), the Radio Management Unit, and the Nav Source Selector.

Integration:

  • Avionics (PFD/MFD/EICAS/AP/RMU): every value is a universal X-Plane dataref / command streamed live by the bridge over the Web API — no Lua needed (N1/N2/ITT, radar-alt, AOA, hydraulics, trim, flaps/slats/gear, control positions, ADF, mach, yaw-damper, the per-mode *_status AFCS annunciation…).
  • FMS / CDU: the same fms-sync.lua bridges the web CDU ↔ the in-sim FMS. It uses the aircraft-agnostic XPLM FMS SDK, so it drives the Citation X's built-in FMS exactly as it does the G1000's — load/build a plan on a tablet and the Citation flies it; build it in the sim and it shows on every tablet.
