SimLoad Manager – Realistic PAX, Cargo & Fuel Ground Operations

Simulate cargo, fuel and passenger loading/unloading times in X-Plane 12. With adjustable parameters for both boarding and deboarding, you can customize the time it takes to load or unload your aircraft in the .lua. This plugin integrates with SimBrief, allowing you to load your flight data and automatically set passenger and cargo numbers. It provides real-time updates on the progress of the loading process and a time estimate for completion in combiation with Simple Ground Equipment & Services.

Description

Bring your X-Plane 12 & X-Plane 11  flights to life with realistic cargo and passenger loading simulations. SimLoad Manager integrates seamlessly with SimBrief to auto-import your flight plan and instantly set passenger and cargo counts. Watch your aircraft load in real time with progress indicators and precise time estimates—adding immersion from the moment you start your flight.

Features ✈️

⏱️ Realistic loading and unloading for passengers, cargo, and fuel - Boarding now adapts dynamically to cargo and fuel progress, minimizing waiting time inside the aircraft and ensuring a smoother turnaround 
📦 Manual entry or SimBrief import for all load values
⚖️ Automatic unit detection (kg/lbs) from SimBrief – or choose manually
📊 Progress bars for each category + dynamic time estimates
Fuel loading simulation - Choose whether you wish to refuel before the rest of the operation or during it.
🎵 Ambient sounds and AI-generated voice alerts
🔊 Sounds that adapt to external/internal views
💾 Settings saved between sessions: SimBrief ID, units, timing presets
🚀 Choose between Realistic, Fast, Very Fast or Custom loading modes with one click
🛩️ Real weight and fuel integration – can be fully disabled if not compatible with your aircraft or add-ons.
🚚 Fully integrated with SGES: Automatically triggers stairs, belt loaders, fuel trucks, cones, and passenger flow depending on your stand type (remote, gate, or jetway)
🔄 Custom X-Plane commands: Start, Reset, Load SimBrief, etc.
🌐 Direct access to SimChecklist.eu for preflight support
📄 Loadsheet system (SLMLS) – Generates a complete and realistic loadsheet, available once SLM has fully completed the loading process.
📱 Flight Sim Deck integration – Native SLM integration developed in collaboration with Gordang enabling real-time interaction and data exchange through the Flight Sim Deck Android application.
✈️ Departure & Arrival modes – Two distinct operational modes, each with their own dedicated steps and workflow.
🔄 Turnaround & RON – Choose between a quick turnaround or a Remain Over Night handling sequence on arrival.
🛎️ Crew Briefing, Catering & Cleaning – New ground handling stages fully integrated into the departure and arrival flows.
🔇 Beacon-aware safety stop – All operations automatically halt when the beacon light is switched on.
🗺️ Automatic new flight plan detection – SLM automatically detects when a new SimBrief flight plan is available during turnaround and prompts for reload.
🌐 ACARS loadsheet uplink for ToLiss aircraft — the loadsheet is sent directly to the MCDU via the Hoppie network. A Hoppie account is required. 🆕
💾 Automatic flight save system. SLM automatically saves its state whenever the mode changes 🆕
💵 Low-Cost mode of quicker operations 🆕

⚠️ v3.0 is a particularly large update. Despite hours of testing, some issues may still slip through — don't hesitate to report anything you encounter in the comments, it's always appreciated and helps make SLM better for everyone.

 

Aircraft Management 🛩️

  • ✅ Laminar Research – Boeing 737-800, Airbus A330-300, MD-82 - should also work with most smaller Laminar aircraft
  • ✅ Zibo / Level Up – Boeing 737-800, 600, 700, 900, 900ER
  • ✅ ToLiss – All aircrafts
  • ✅ X-Crafts – E-Jets / ERJ Family
  • ✅ Flight Factor – Boeing 757-200, 757-300, 757-200F, 767-200, 767-300, 767-400
  • ✅ FPS – Boeing 747-800
  • ✅ Rotate - MD80
  • ❌ Q4XP – Excluded. SLM automatically disables its weight and fuel integration for this aircraft, as it requires the use of its own tablet for fuel and weight management.

Other aircraft should work in most cases, but compatibility may vary depending on how the add-on handles fuel and payload datarefs. If you'd like your aircraft to be added to the supported list, please provide the following:

📋 To submit an aircraft for compatibility testing:

  • Fuel:

    • ICAO type designator (e.g. B738, A320)

    • A screenshot from DataRefTool showing the m_fuel dataref with the aircraft fully fuelled, indicating:

      • Which tanks are present

      • Which index on m_fuel corresponds to which tank

      • The order of the tanks in the array

    • If m_fuel is not used by the aircraft, provide the equivalent custom fuel dataref used by the add-on.

    Payload:

    • A screenshot from DataRefTool showing the m_stations dataref with a full passenger and cargo load, indicating:

      • Which stations are present (seats, cargo holds, etc.)

      • Which index on m_stations corresponds to which station

      • The order of the stations in the array

    • If m_stations is not used by the aircraft, provide the equivalent custom payload dataref used by the add-on.

 

If m_fuel is not used by the aircraft, provide the equivalent custom fuel dataref used by the add-on.

Installation 🛠️

Before installing new version, you must delete the old files. 

  1. Extract the contents of the archive. 
  2. Place the following file into the FlyWithLua/Scripts/ folder of your X-Plane installation:  SimLoadManager.lua 
  3. Place the entire SLM-Data/ folder into the same directory (do not rename it or its contents)

Prerequisites ⚠️

Optional but still really good 👍

  • SimBrief account is required to import pax & cargo data.

Changelog

  • v4.3 14. Aug 2026
    🆕 Added:
    Top-Fuel command – New X-Plane command FlyWithLua/SimloadManager/TopFuel (bindable to any joystick/keyboard button or hardware panel), paired with a writable dataref (FlyWithLua/SimLoadManager/fuel_topup_target) to set the target fuel figure externally. Applies the fuel target exactly like the in-window "Fuel Top-Up → Apply" button — handy for external apps and companion tools.

    Adjustable plugin font size – New "Plugin font size" control in Settings → Units & Display. Choose between Default and 9 crisper font/size combinations (ProFontWindows / Roboto-Light / Roboto-Regular, 13/16/20px) for SimLoad Manager's windows. Fonts install automatically; requires FlyWithLua NG 2.8.15 or newer. ⚠️ Please note: This will change the font used for all Flywith LUA windows; this is a limitation.

    Walkaround V2 by Furax84 plugin integration – If the Walkaround plugin is installed, SimLoad Manager now mentions it during the crew briefing step and adds a "Start Walkaround" button to launch it directly.
  • v4.2 24. Jul 2026
    🆕 Added :
    Calculation of the ZFWCG for Toliss aircraft, integrated into the loadsheet
    Added the Rotate MD80 to the list of supported aircraft
    Adding new KO-FI donors

    ⚙️ Changed:
    A safety feature has been added to the flight phases to check whether or not the Beaconlights are present. This could have prevented the flight from proceeding smoothly.
  • v4.1 12. Jul 2026
    Correction of values in CDPLC/TELEX loadsheet submissions where the unit was in pounds.

After installing the plugin, whenever I try to open it while playing X-Plane 12, I get a “Lua stopped” warning, and the plugin gets stuck on a black screen.

A really good addon and much needed. Is it compatible with the Magknight 787?

@middi25 I tried it myself today and I don’t have that problem on those aircraft. Which simulator are you using? Please go here https://forums.x-plane.org/files/file/93858-simload-manager-realistic-pax-cargo-fuel-ground-operations/, it’ll be easier.
