Plugin Helper Interface (PI_CockpitdecksFMSBrowser)

G1000-style FMS layout expects the following datarefs and commands.

Current (used by fms_fpl, fms_nav, fms_load pages)

fms_browser (plan browser / LOAD)

3-row paged list (same paging model as fms_legs on FPL): show plans 1–3, then 4–6, etc.

  • list_row_1_filename … list_row_3_filename — file basename without .fms
  • list_row_1_timestamp … list_row_3_timestamp — file timestamp label used on the LOAD page
  • list_row_1_index … list_row_3_index — 1-based index of that row’s plan in the full sorted list (empty if row blank)
  • list_row_1_route … list_row_3_route — departure / destination line for the row’s plan
  • list_row_1_wpt_count … list_row_3_wpt_count — waypoint count in file
  • list_row_1_max_alt_ft … list_row_3_max_alt_ft — max waypoint altitude in file (ft MSL; 0 if empty row)
  • list_row_1_distance_nm … list_row_3_distance_nm — total great-circle distance along parsed route (nm)
  • list_row_1_is_selected … list_row_3_is_selected — highlight when that row’s plan is selected
  • list_page — e.g. 1/4 (current page / total pages)
  • list_sel_count — which visible row (1–3) is selected on the current page, e.g. 2/3 or -/3 when none; use list_page + row list_row_*_index for global plan order
  • list_sort_key / list_sort_mode — NAME or TIME
  • list_sort_direction — ASC or DESC
  • list_snapshot — JSON for encoder binding (window + row indices + selection + sort_key + sort_desc)
  • Commands: list_scroll_up, list_scroll_down — move by one page (three plans), not one-by-one (Loupedeck SR22 Load binds these to E0; deck keys may use sort or refresh instead)
  • Commands: list_sort_toggle_key, list_sort_toggle_direction — toggle the browser sort key/direction
  • Commands: list_sort_filename, list_sort_timestamp, list_sort_asc, list_sort_desc — explicit setters if you want fixed-state actions

Legacy single-selection datarefs (reflect the tapped/selected plan, not the visible page):

  • plan_name, plan_filename, plan_departure, plan_destination
  • plan_distance_nm, plan_waypoint_count
  • plan_dep_runway, plan_dest_runway, plan_sid, plan_star
  • index, count, status
  • loaded_distance_nm — total distance of loaded route (nm)
  • Commands: previous, next — move selection within the current visible 3-row page only (no page change); load, refresh

fms_browser (live FMS)

  • fms_active_ident, fms_active_index, fms_active_altitude
  • fms_first_ident, fms_last_ident
  • fms_entry_count

fms_legs (FPL waypoint list)

  • row_1_index, row_1_ident, row_1_alt, row_1_is_active, row_1_is_selected, row_1_status
  • (same for row_2, row_3)
  • selected_index, entry_count, snapshot, window_start (read=page 1,2,3…; writable=set page)
  • Commands: scroll_up, scroll_down — move by page (1–3, 4–6, 7–9…), not 1-by-1
  • Commands: direct_to, select_row_1, select_row_2, select_row_3, clear_selected

Desired additions (for full G1000 parity)

Per-waypoint in FPL (row_X_)

  • row_X_dtk — desired track to that waypoint (°)
  • row_X_distance_nm — distance to that waypoint (nm)

NAV page

  • distance_to_destination_nm — remaining distance to last waypoint
  • ete_to_destination_min — ETE to destination
  • nav_source — "GPS" | "VLOC" (for SRC tile, future toggle)

X-Plane datarefs used (verify existence)

  • sim/cockpit2/radios/indicators/gps_dme_distance_nm — dist to next WPT
  • sim/cockpit2/radios/indicators/gps_dme_time_min — ETE to next WPT
  • sim/cockpit2/radios/indicators/gps_bearing_deg_mag — DTK
  • sim/cockpit2/radios/indicators/gps_nav_bearing_deg_mag — BRG to WPT
  • sim/cockpit/radios/gps_course_deviation — XTK (nm)
  • sim/cockpit2/gauges/indicators/ground_speed_kt
  • sim/cockpit2/gauges/indicators/ground_track_mag_pilot
  • sim/cockpit2/radios/indicators/fms1_act_eta_hour, fms1_act_eta_minute
