Sync (FlyWithLua companions in plugins/ + server/fmssync.js): - FMS flight-plan two-way sync (App <-> in-sim FMS) via fms-sync.lua - G1000 UI-state publish (page/range/inset) via ui-sync.lua + CDI source, baro, map-range follow - Terrain awareness: elevation grid probe (terrain-probe.lua) -> red/yellow MFD overlay vs aircraft altitude PFD: - AFCS mode annunciation bar from autopilot _status datarefs - CDI source GPS/VLOC colouring, BRG1/BRG2 pointers + DME windows, marker beacons - magenta speed/altitude trend vectors, selected-altitude alerting - time-based (frame-rate-independent) smoothing for attitude/heading/tapes MFD: - nav data bar (DTK/ETE/active leg), airways overlay from earth_awy.dat, compass rose anchored to the ownship Dialogs (NEAREST/FLIGHTPLAN/DIRECT-TO/PROCEDURES): - flat, square, embedded G1000 look (no shadow/rounded/transparency) - compact lower-right placement, no close X (softkey toggles), single window - NEAREST 2-line entries (ILS/VFR, COM freq, runway length), PROC action menu Service worker: network-first HTML so reloads pick up new builds (cache v2).

-- ============================================================================

-- The web MFD can't read X-Plane's scenery elevation over the Web API. This
|

-- script samples a grid of terrain heights around the aircraft with X-Plane's
|
||
-- terrain probe and writes them to terrain.json in the sync folder; the bridge
|

-- streams it to the tablets, which colour it red/yellow vs aircraft altitude
|

-- (G1000 TAWS). See terrain-sync in server/fmssync.js.

-- INSTALL: copy to <X-Plane>/Resources/plugins/FlyWithLua/Scripts/ (alongside
