Expands the single-page CDU into a Collins/Boeing-style FMS per the X-Plane FMS
manual: FPLN (origin/dest/flt-no), LEGS (waypoints, insert/delete/activate),
DEP/ARR (SID/STAR/approach from the CIFP parser, with transitions), DIR
(direct-to), VNAV (cruise/target-speed/path-angle; VPA feeds the shared descent
profile), and MENU (load/store .fms). Page keys + scratchpad + LSKs + keypad.
All edits flow through the shared flight plan, which fms-sync.lua mirrors two-way
into the in-sim FMS — so the app CDU and the aircraft CDU stay synchronized
(no new Lua needed; reuses the existing sync + procedures.js).
