What Does it Do?

Self-Loading Cargo allows you to interact and work with a virtual cabin crew and ground crew to ensure the safety, security and satisfaction of your passengers throughout the course of your airliner flights.


Intercom, Public Address System & Ground Radio

Make realistic in-flight announcements to your passengers, work closely with your cabin crew to manage the aircraft during different phases of flight, deal with technical setbacks, medical issues or problematic passengers and manage the in-flight services provided throughout the flight.

You can work with your ground crew via the ground radio to manage loading the aircraft, pushback from the gate and disembarking your passengers after arrival - all with localised voices based on the airport locations.

Authentic Seating Arrangements and Inflight-Services

Using authentic aircraft cabin layouts to control the seating arrangement and facilities onboard the aircraft, Self-Loading Cargo simulates individual passengers in real-time using their own unique personalities and requirements to determine how much they enjoy your flights and how they react to any issues that may occur onboard or how well they are treated.

Pilot Grading & Passenger Satisfaction System

Throughout the course of your flight, Self-Loading Cargo continually monitors how well you control the aircraft and how effectively you communicate with the cabin crew and passengers in the back.

Additionally, your passengers are individually simulated in real-time and they will rate their flight based on how satisfied they are with the service levels, punctuality, communications and of course their flight comfort - all mixed with their own individual personalities and quirks.

Once you land, you'll receive a flight report showing any comments and a pilot rating to show how well you've done and where you can improve on your next flight.

What does it add to your simulator?

Developed from the ground-up to simulate airline protocols as realistically as possible, Self-Loading Cargo brings a whole new level of immersion (and workload!) to your airliner flights in Microsoft Flight Simulator, P3D, FSX and X-Plane1.

What Our Customers Say

Thousands of flight simulation enthusiasts like you have transformed their hobby into one of the most immersive and involving experiences available on a desktop computer - here are a few quotes from some of them:

Wow, this was definitely worth the wait. I can't fly without SLC nowadays - thank you for creating this wonderful app!

Fabian C., Italy.

I used to love FSPassengers back in the day but this is something else. Completely superior to any other product on the market when it comes to creating immersion and keeps getting better and better with every update.

Callum F., United Kingdom

I enjoy your work, Self-Loading Cargo makes me enjoy my simulator more because it means i have things to do while in the cruise and I won't fly without it any more.

Raheem Q., United Kingdom

It is the best addon I have owned for the price. I hope for more updates so it will get better and better!

Vasquez B., Portugal.

The Dev get's an A+ rating for creativity, thoughtfulness and consideration of subtle details of the processes of pilot, cabin and ground crews--stuff I really never thought about much prior to starting SLC

Noel, U.S.A.

I love how sassy the cabin crew are if I am a bit enthusiastic when I land - not to mention the shouting passengers! Thank you for the immersion I've been missing from my flight simulator, I can't fly without it any more.

Gareth A., Ireland.

Absolute gamechanger. This is something I've been missing for my entire "simming" career and now I can't imagine flying without it.

Neil R., United Kingdom

This is a work of art - now with the GSX integration it's like everything just works together and feels like a real flight.

Chris K., United Kingdom

Thank you for making it stay out of the way! Other programs I tried were up in my face distracting me from flying, but SLC sits to the side and doesn't break the immersion at all - while still being easy to use when I do need it. Great design!

Darrell J., U.S.A.

Wow, a huge amount of work gone into this addon, great job.

Brian M., Scotland
