I didn't realize it was an older communication. However I went onto youtube and indeed found the live stream they mentioned so they have been accurate. I just watched some of it and this sim is looking quite impressive to me and as I listen to the gentleman doing the live stream, he seems to be saying all the right things. From what I can see too, this is not some budget "farm and construction simulator" on Steam. This looks like a serious effort and appears to have a lot of quality and also a level of immersion that not many sims have.
The gentleman, when asked about realism vs. assessibility, stated that he is a pilot and that they are looking for a balance but with the emphasis on simulator. The video shows their interactive component system. Looks like most things are modeled and can be interacted with. For example, while doing a walk around and wanting to check his stall warning indicator, he had to get into the plane and turn the master switch on. Also there is a wear and tear system part of which is based on your own flying and ability to take care of the plane. For example if you let your starter motor degrade, you may have to get out and hand start your propeller. Also cargo loading has an effect on aircraft performance. When he takes off it looks like its having a hard time climbing on take off because of the barrel he put in the back.
The world is also a truly open world. So from a first person perspective while in your home hanger, you could actually walk out the hanger doors and walk across the map if you wanted. He also showed the crash model which looks really good. It looks similar to Rise of Flight in that its dynamic. No switching out to a damage model. Aircraft skin can actually crunch and in his crash his wing came off and the prop got bent. Also, when he opened the hatch and got out, the change in weight distribution caused the aircraft to roll over.
There's a real tangibility to this one that looks great. Looks like most switches are clickable. He says there will also be Track IR and VR support.
