We have two new friends: COS and TAN. It wasn't love at the first sight but finally we made friends


In theory these points should be the reference for the distortion-free projection. The tension increases. We are really excited if this will somehow work.


Calculation of coordinates for reference points

Simulation of front reference points at flat front looks promising:

Simulation of left and right side looks weired but remember we have some angles in the side walls

Nicola from Fly-Elise told us that our type of screen is not supported by Fly-Elise and therefore cannot be calculated by the program. For sure we don't blame this on the software. Our environment is indeed really tricky. To be honest - we did not expect that sort of trickyness.

Today we tried to do the first manual adjustments and quickly came to the conclusqion that this is a hopeless plan. So we went back to the desk and do some more theory.

We thought about the basic challenge. We think the major plan is to get the visual impression of a surround view on crazy angular walls. To start with a simply thought - we neglect the angled side walls try to project a round view on rectangular walls. To do so, we will need to calculate several positions of markers.

The sample below shows the different distance of markers on the wall based on this round view.

Today we had enough time to do great progress on our internal project.

We spent a lot of time finding the most suitable projectors for our very special room situation. It came out that Vivitek projectos with a throw ratio around 0.3 will do the job. At least in theory. We have been able to calculate the room in Fly-Elise but at the end a technicality made us change the plan. The projector data in Fly-Elise have been correct, but these projectors throw the light via a mirror as they are designed to generate a very wide view even if they are close to a wall.

So all angles had been wrong. The problem was easily to solve as we have a very high room cover. So we place projectors much higher which resulted in a really amazing full view. Actually better than we expected.

Now as we got the proof of concept we will need to do fine adjustments and then mark the projection area. We plan to paint the room in black/dark-grey color to avoid unwanted reflections so we need to define the max projection area. To be sure that everything will be properly adjusted we now will need for the computers before we can do further amendments to the room.

Admittedly. The picture looks a bit confusing. Due to the oblique walls, we do not want to fix the projectors on the ceiling, but on the side walls.For this we have thought of a combination of aluminum profiles and projector brackets. We'll see if it works like this.



Projectors have arrived. The excitement rises...

Now we import the projection area into Fly-Elise. Together with the 3D-model of our simulator we have the perfect workspace.

(Note: You can find our 3D-model in our Support Area in case you like to use it for your own calculation.)

We tried several types of projectors. Main issue even with short throw projectors was the necessary height for a proper positioning. We basically have enough space for a high positioning but due to the wall angles the picture will be quite flurry. So we needed to find projectors with an utltimate short throw.

We finally found a Vivitek DH758UST which looks good from a technical view. This projector is a bit more expensive than others but it has the advantage to be place right above the cockpit.

So we will order them and try it. While waiting we have enough to do with preparing the room...











As you have seen in earlier posts the projection area of our simulator in Bottrop will be a bit tricky to work with. Especially the angle of the roof will be a real challenge. But let's see how far we get.

We will try to confirm the possibility to use the walls as projection area with the help of Fly-Elise. To do so we firstly design a simple model of our projection area with 3D builder a program that's delivered with Windows 10 and easy to use.








So far so good. This will be our projection area.





The team is working on orders while we are looking for more space.... ;-)

Thanks to all customers who have visited us at this years FSweekend in Lelystad. It was again a real pleasure to see many of you again and to see new customers who are into flying an A320.

This time we showed a complete cockpit. The team managed to set the simulator up on a Friday night within 3 hours after a drive of more than 700 kilometers!

Setup almost done... ;-)

At the FSweekend 2016 in Lelystad we had the pleasure to welcome Tom David from Flight Sim Academy at the flight deck. Tom spontaneously set up our simulator and impressed the audience with his expertise.

Please note: Tom is not a real 320 pilot or a student pilot. His experience is based on flying A320 in the desktop and on reading the FCOM. Great job, Tom - even though some knobs did not respond as they should, due to previous customer "testing". ;-)

It was a pleasure having you with us.




Some of you plan their flight simulator location in an own 3D environment. To make your planning work easier we provide a basic 3D model of our A320 simulator. Of course this model does not have too much details but it should allow you to estimate required space at your event location or your home.

Furthermore you can use this 3D model to plan your projection. Our partner Fly-Elise has a great software for this and you can import our model directly into their software to calculate position of your projectors and minimize shadow throw.


To download the model please register to our support portal.



You may ask you why we partly show very little details of our products on our website. Well, you can see below a reason for this.

There are people outside that not only take our product ideas and pictures but also copy our text and claims word by word.

We really feel flattered. Only cool brands are copied by others. ;-)

We started in 2015 with the clear goal of building an A320 cockpit simulator for commercial use in Leipzig, Germany. At first we had to find a supplier for electrical parts and all required structural components. Ideally for a complete solution. Furthermore we needed a reliably partner who supports us and ensures that we can run our business continuously.

After some research we made contact with VIER IM POTT and after some kind email communication it became clear – we found the right partner for our project. On the pictures of their website everything looked very convincing and original but we wanted to see it in real before investing our money.

We took the chance to visit the production site in Dresden and we were quite impressed about quality of the cockpit components and the knowledge paired with enthusiasm of the VIER IM POTT team. All questions had been answered.

Once decision has been made we very excitingly looking forward to the delivery. Due to the distance to Dresden we picked up components ourselves and started building the simulator in Leipzig. As a very early customer we experienced some minor difficulties but the team was helping fast and solution oriented and we could clearly see that they wanted us to be successful.

Since October 2015 our simulator is on-duty now without any considerable problems. Our customers have a great flying experience and we receive 100 % positive feedback from our guests. Many thanks to VIER IM POTT! Our next simulator will be again from you guys – for sure…!

We received this feedback from Mario almost one year after installation. So we took the chance to visit his simulator in Leipzig. It was fantastic to see his business growing.

Mario has realized so many really great ideas to make a flying event a remarkable experience for his customers. We never saw a simulator build with so much love to details. Many thanks for this experience, Mario! It was a real pleasure working with you.

As the dream of a round 220 degree projection area seems not to come true, we plan to use walls and ceiling as projection area. The expected result will not be round of course, but also have the 220 degree view.

First we need to contruct the front projection area. Challenge here: we will need to access the outside door for cleaning and sometimes get fresh air.

As we will not be able to make the projection area movable we trust in our personal degree of fitness and provide a 50 cm high passage below the projection area. ;-)

BTW. Dimensions seem to be ok - despite of the sloping walls of course. In general we have around 4.5 meters width and height. A real benefit will probably be the high ceiling as we can place the forward projector very high not disturbing the light of the side projectors. But this will be math in a few weeks.

The access door to the room does not seem to be place properly. But due to the sloping walls there es no other chance to place it - and it's already there...
