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 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.

⚠️ 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
  • ❌ 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

  • v3.4 11. Mar 2026
    🐛 Bug Fixes and changes:
    Revision of the Arrival > In Flight > Departure cycle for greater consistency.

    Correction of the system's operation in lbs, which was incorrect.
  • v3.3 08. Mar 2026
    🐛 Bug Fixes and changes:
    The flight plan is no longer deleted between stages.
    Data for unloading the aircraft is based on the loadsheet and no longer on the flight plan.
    Once loading has started, it is no longer possible to load a flight plan before the new flight plan at Turnaround.
    The interface better corresponds to the stages.
  • v3.2 05. Mar 2026
    ✨ New Features & Improvements
    Manual & Flight Sim Deck data sources: You can now load a flight without SimBrief. Select your preferred data source in Settings — Manual lets you enter PAX, cargo and fuel directly in SLM, while Flight Sim Deck pulls your data automatically from the app in one click. The Flight Sim Deck option only appears if the app is installed (Please be patient for a few days; the Flight Sim Deck feature has not yet been released).

    Adaptive loadsheet: The loadsheet now adapts to your data source. In Manual and Flight Sim Deck modes, a simplified version is displayed showing only the relevant information — weight calculations requiring SimBrief data are hidden.

    Captain name: A new Captain field has been added to the settings. Your name will appear on the loadsheet under Approved by and persists between sessions.

    XCraft Embraer — Real Payload Fill (R)enabled: After extensive testing, Real Payload Fill is now fully supported for the entire XCraft Embraer family (E135, E140, E145, E45X, E170, E175, E190, E195, E19L, E35L).

    Don't call jetway / stairs: The existing Do not call stairs checkbox has been extended — it now also prevents SLM from triggering the jetway, useful if another plugin such as AutoDGS is already handling it.

    Improved arrival detection: Arrival mode is now triggered by beacon light state rather than altitude, making detection more reliable across all aircraft types. The old system could cause a LUA Stopped error when changing aircraft.

    Turnaround — new flight plan prompt: During turnaround, SLM now clearly prompts you to load your next flight data regardless of your data source, before proceeding to next steps.

    🐛 Bug Fixes
    ToLiss payload weight: PAX distribution is now correctly initialized to 50% at the start of each boarding sequence.

@ibrahimlamis I can't test it, but some people tell me it works, best to test it with the FlywithLUA version on xp11.

Sucks that this wouldn't work on XP11

Hi @captainwalker As for GHD, I haven't had time to look into it yet, but it's on my to-do list. As for accounting, I've started digging into it and even written some code. But the more I dig... the deeper I get myself into trouble. It's very complicated to have something versatile between planes when it comes to loading.

I was wondering if we can get a compatibility with ground handling deluxe. So it calls the GHD vehicles instead of SGES. And maybe we can get actual loading in the future so I don't have to set any weight in the aircraft

@NoorTheAviator PLease read the description 👀 "✈️ 100% aircraft-compatible – no weight changes, works with all add-ons - No aircraft data modified"

Fuel doesn’t go up after refueling is in progress also please make cargo and passengers load at the same time
