Options

docs/OPTIONS.md

Everything that can be set, in one place:

  1. Options you can set now: L:vars of this rewrite.
  2. Troubleshooting switches: sign flips for a problem found in the sim.
  3. Zibo's options and their status: every option of Zibo's EFB / config file (B738X_*.cfg, written by B738.a_fms.lua), with what the rewrite does with it today.
  4. Cockpit model variants, fixed displays, diagnostics (read-only) at the end.

How to set an L:var. In MSFS developer mode: Tools → Behaviors, select the aircraft, LocalVariables tab, find the L:var and enter the value; or any tool that writes L:vars. The EFB settings page will write the same L:vars when the EFB is rewritten. Changes take effect immediately. An L:var that was never set reads 0, so 0 is always the default and the default is always Zibo's behaviour, unless noted otherwise. L:vars reset at each flight start except where Kept says otherwise.

Last updated: 2026-11-05 (systems module build 37).

1. Options you can set now#

L:var Values Default What it does Kept Since Details
L:LU737_THR_HW_MODE 0 / 1 / 2 0 Hardware throttle against the autothrottle (not a Zibo option: X-Plane keeps the joystick apart from the A/T's levers, MSFS has one throttle). 0 = last mover: while the A/T drives, axis noise is ignored and moving the hardware more than 3 % is a manual override relative to the A/T's lever (no thrust jump); the A/T takes the levers again 2 s after the hardware stops; without the A/T the hardware takes the levers once it reaches them (pickup). 1 = follow the A/T: the hardware is ignored while the A/T drives, otherwise it drives the levers directly. 2 = follow the hardware: the levers always follow it. The reverse range from the hardware always passes at once yes (\work\lu737_options.txt) build 36 wasm/src/core/thr/thr_arbiter.h, docs/AFDS_AUDIT.md A6
L:LU737_IRS_ALIGN_TIME 0 / 1 / 2 / 3 0 IRS alignment time (Zibo ALIGN TIME): 0 = real (by latitude: 300 s at the equator, 333 s at 22° N, 400 s at 40°, up to 1020 s at 82°), 1 = fast (60 s, Zibo SHORT), 2 = instant (NAV about 3 s after the selector reaches NAV; not Zibo), 3 = long (150 s, Zibo LONG). Read when an alignment starts no build 15 docs/specs/irs.md §4
L:LU737_EEC_HOTSTART_OFF 0 / 1 0 1 = no EEC hot-start abort (not Zibo): a wet start runs into the red until the start lever is cut; 0 = Zibo, the EEC aborts a ground hot start at about 711 °C no build 13 wasm/README.md
L:LU737_EICAS_FUEL_FORMAT 0 / 1 0 Upper EICAS fuel display (Zibo FUEL GAUGE): 0 = FUEL QTY box, 1 = three round gauges no M4b docs/EICAS.md
L:LU737_EICAS_FUEL_UNITS 0 / 1 0 Fuel units on the EICAS (Zibo UNITS): 0 = KG, 1 = LBS no M4b docs/EICAS.md
L:LU737_DU_PAGE_BUILD_OFF 0 / 1 0 1 = show DU pages at once (not Zibo); 0 = Zibo / LevelUp page build (lower DU ENG page drawn in stages over about 1.2 s after an MFD ENG / SYS press) no M4c docs/LOWER_DU.md
L:LU737_DU_GAIN > 0 0 (= 2) Emissive strength (brightness) of all display surfaces in MSFS; 0 or unset means 2 no M4a docs/TEST_PLAN.md M4a
L:LU737_SIM_GRAPHICS_VIEW_HIDE_YOKE 0 / 1 1 (set at load) Yokes shown (1) or hidden (0), as Zibo HIDE YOKE; a click on the yoke toggles it no build 31 below
L:LU737_FMS_HZ 0 / > 0 20 (set at load) Rate of Zibo's FMS scripts (M5c): how often per second they run (each run gets the elapsed time, Zibo's code is time based). Lower = less WASM time per sim frame, slower CDU response; 0 = the FMS stops (L:LU737_FMS_STATE 2), back above 0 = it resumes. Readouts: L:LU737_FMS_STATE (0 not loaded, 1 running, -1 failed to load, 2 stopped), _MS / _MS_MAX (ms per FMS run, average / highest), _LOAD_MS, _ERRORS (Lua errors), _MEM_KB no build 44 wasm/src/core/fms/fms.h, docs/M5C_PLAN.md
L:LU737_MANUAL_REVERSION 0 / 1 1 (set at load) Flight controls without hydraulics (A and B both below 1000 psi, e.g. cold & dark): the stick's elevator / aileron axes are masked and passed on at 60 % authority and 0.8 full scale per second, as the 737's manual reversion feels heavy and slow (MSFS cannot load the stick). Since build 54 the axes stay masked while this is 1 and the systems pass the stick on as it is when there is hydraulic pressure (adding the mask again after removing it did not mask, build 49). 0 = off (not masked). L:LU737_MANUAL_REVERSION_ACTIVE shows it; the console prints "manual reversion on / off"; whether the mask holds: §2 readouts no build 48 wasm/src/core/systems_sys.cpp updateReversion
L:LU737_NAV_REBUILD 0 / 1 0 1 = read MSFS's navdata again. Since build 55: the facility lists (the world's waypoints, navaids, airports: positions) are written at once and the FMS reloaded with them (L:LU737_NAV_STATE 2 within seconds); in the background, nearest first, the VORs' / NDBs' frequencies and names (L:LU737_NAV_DETAILS %, 100 = the files complete for the next load). On demand: an airway the FMS does not find (VIA): followed from the waypoint before it (L:LU737_NAV_AIRWAYS counts them); an airport's runways, transition altitude / level, localizers and procedures when it is entered (_PROCS, _PROCS_FAILED): Zibo shows NOT IN DATA BASE / INVALID ENTRY the first time, enter it again a moment later. Readouts: _FAIL (1 the list requests refused, 2 not answered, 3 files not written), _FALLBACK, _LISTED, _FOUND, _REQUESTS, _LOST, _RECV_LAST, _COUNTS. L:LU737_NAV_BATCH: requests in flight (default 200) no build 52 / 55 wasm/src/core/fms/nav_provider.h, docs/M5C_NAVDATA.md
L:LU737_ILS_REALISM_OFF 0 / 1 0 NAV receiver realism (not a Zibo option: X-Plane's radios are X-Plane's). 0 = on: the glideslope's false paths at 6° (reversed) and 9°, needles that wander and jump with flickering flags beyond the service volume, beam bends, the back course's reversed sense, the DME's 2–4 s lock-on and 8 s memory; the AFDS, the FMS and the PFD / ND all read it. 1 = MSFS's clean signal. Readouts L:LU737_NAVn_HDEF, _VDEF, _LOC_VALID, _GS_VALID, _DME, _DME_VALID, _GS_THETA, _GS_SIGN, _LOC_SIGN no build 71 docs/ILS_REALISM.md
L:LU737_AP_ROLL_GAIN 0 / 0.2–3 0 (= 1) Multiplier of the autopilot servo's bank gain (bank error → roll rate, 1.0 /s since build 45). Lower if the A/P rolls in too sharply or rocks the wings; 0.5 = the gain of builds 25–44 (S-turns on the localizer). Not a Zibo option (the servo is ours) no build 45 wasm/src/core/afds/servo.h, docs/AFDS_AUDIT.md A9
L:LU737_ENGINE_AIR_START 0 / 1 0 Ground air start cart connected (Zibo's EFB ground service) until the EFB is rewritten no M3 wasm/README.md

2. Troubleshooting switches#

Leave at 0. They exist to correct a direction found wrong in the sim without a new build; tell me when one is needed so the default can be fixed.

L:var Values What it does Since
L:LU737_AP_ELEV_SIGN 0 / -1 -1 reverses the autopilot's elevator command (A/P pitches the wrong way at once) build 25
L:LU737_AP_AIL_SIGN 0 / -1 -1 reverses the autopilot's aileron command (A/P rolls the wrong way at once) build 25
L:LU737_LOC_DOTS_PER_CDI 0 / 1 1 = the localizer deviation as MSFS's CDI, ±127 = ±2.5 dots (builds ≤ 44); 0 = by the measured beam width, 1 dot per degree (readouts L:LU737_NAV1_LOC_HALFWIDTH / NAV2_: the measured half-width in degrees, 2.5 until measured) build 45
L:LU737_AP_TRIM_SIGN 0 / -1 -1 reverses the autopilot's / electric pitch trim sent to MSFS (trim runs away) build 25

Manual reversion readouts (read only, build 49; wasm/src/msfs/gauge.cpp): whether the stick mask holds.

L:var Meaning
L:LU737_SIMCONNECT 1 = the systems module's SimConnect is open (throttle and stick masks possible); 0 = not
L:LU737_REV_MASKED 1 = the stick's AXIS_ELEVATOR_SET / AXIS_AILERONS_SET are in the masked group (reversion on); 0 = not (reversion off); -1 = SimConnect refused
L:LU737_REV_SC_EVENTS count of stick events SimConnect handed the module (it gets them when they are in the masked group)
L:LU737_REV_KEY_EVENTS count of the pilot's stick events the key event handler saw while reversion was on
L:LU737_REV_KEY_LAST the last of those: 1 AXIS_ELEVATOR_SET, 2 ELEVATOR_SET, 3 AXIS_AILERONS_SET, 4 AILERON_SET
L:LU737_SIMCONNECT_EXCEPTION the last SimConnect exception number (0 none); also in the console
L:LU737_SIMCONNECT_EXCEPTION_INDEX the parameter of the refused call (SimConnect's dwIndex)
L:LU737_SIMCONNECT_EXCEPTIONS how many SimConnect exceptions this session
L:LU737_NAV_REFUSED facility requests MSFS refused (a fix asked for as each type; an airport it does not know): ended at once, not in the exceptions above

2b. Failures (Zibo's failure items, X-Plane's failure menu)#

Set to 1 in the sim's L:var tool to fail, 0 to repair (applied when the value changes; not kept between flights).

L:var Zibo item What happens (build 46)
L:LU737_FAIL_APU_OVERSPEED engine[20] On a running APU: the governor fails, N1 runs up past 100 % at the spool-up rate and the ECU trips at 107 % (about 3.7 s; owner's model, 1680b1d; Zibo trips at once): APU off, generator off, OVERSPEED light (stays lit up to 300 s after OFF, Zibo's light memory), APU six-pack
L:LU737_FAIL_APU_LOW_OIL_QTY engine[21] APU shuts down, LOW OIL PRESSURE
L:LU737_FAIL_APU_LOW_OIL_PRESS engine[22] LOW OIL PRESSURE while starting / running, the running APU shuts down
L:LU737_FAIL_APU_START engine[19] The APU does not start (X-Plane's APU failure): FAULT
L:LU737_FAIL_APU_FIRE engine[18] No effect yet (the fire detection is not rewritten)
L:LU737_FAIL_APU_BLEED_VALVE pressurisation[6] APU bleed valve frozen
L:LU737_FAIL_APU_PRESSURIZATION pressurisation[15] Zibo's APU pressurisation failure

3. Zibo's options and their status#

Every option Zibo's FMS script writes to its config files, with Zibo's default (its preset / flight start value). Status:

  • L:var: settable now (section 1).
  • fixed: the rewrite uses Zibo's default; it becomes an EFB setting when the EFB is rewritten. Options the ported zibomod code (AFDS, Systems, hydraulics) reads are given Zibo's default by the integration (systems_afds.cpp, systems_sys.cpp); before build 37 several read 0 (marked).
  • not yet: the system or feature behind it is not rewritten yet (FMS, sound, EFB, ground services, model variants, failures).
  • n/a (MSFS): X-Plane-specific (joystick axis mapping, X-Plane plugins and hardware, rendering): MSFS's own settings do this.

Cockpit model variants set at load (build 31)#

The systems module sets these once when it starts, to the values Zibo loads with (they choose which parts of the cockpit model are shown). Writing another value afterwards changes the model at once.

L:var Set to Meaning
L:LU737_SIM_GRAPHICS_VIEW_HIDE_YOKE 1 Yokes shown (0 hidden); a click on the yoke toggles it
L:LU737_HUD_DISABLE 1 HUD (HGS) not installed
L:LU737_RAAS_NOT_INSTALLED 1 No RAAS panel
L:LU737_RMI 1 RMI instead of the standby navigation display
L:LU737_ALT_INTV_BUT, L:LU737_SPD_INTV_BUT 1 MCP with ALT INTV / SPD INTV buttons
L:LU737_LAYOUT_1_HIDE 1 Cabin layout 1 hidden

L:LU737_TAB_* 1 EFB tablet parts and click zones shown

Diagnostics (read only, for bug reports)#

Not settings: counters and states to read in Behaviors → Variables when reporting a problem.

L:var Meaning Since
L:LU737_WASM_BUILD Build of the loaded systems module (must match the latest release notes) M1
L:LU737_DU_UPPER_PWR, L:LU737_DU_LOWER_PWR Display unit power (bus power and Zibo's 32 s warm-up) M3a
L:LU737_LOWER_DU_PAGE, L:LU737_LOWER_DU_PAGE2 Lower DU page: 1/0 ENG, 0/1 SYS, 0/0 blank, 2/0 compact on the upper DU M4c
L:LU737_WASM_ALIVE, L:LU737_WASM_FRAME, L:LU737_WASM_TIME The systems module runs (frame counter, sim time) M1
L:LU737_THR_HW_STATE_1, _2 Hardware throttle state per lever: -1 throttle events not masked (SimConnect unavailable), 0 waiting for the hardware to reach the lever (pickup), 1 A/T has the lever, 2 manual override, 3 hardware has the lever build 36
L:LU737_AP_SERVO_PITCH_ON, _ROLL_ON, _ELEVATOR, _AILERON, _PITCH_CMD, _ROLL_CMD Autopilot servo: channels engaged, the elevator / aileron sent, the commanded pitch / bank build 25
L:LU737_MSFS_BUS_VOLTS MSFS's own electrical bus voltage (the coupling to MSFS's electrics) M3

Adding an option#

  1. Name it L:LU737_<WHAT> with 0 = Zibo's behaviour (default), so an unset L:var changes nothing.
  2. Add a row above (values, default, effect, since, details) and to the component's own doc.
  3. Add a test of both values.
