RealEnvironmentX or REX have released a short statement on the development of SimAir.
SimAir has been in development for quite some time now and since the REX developers had stopped putting out updates, status reports etc, people assumed that the project was dead, but a recent post on the REX forums clearly states “it is still very much alive“. A REX Developer also said that the project is simply on hold due to other focuses of other REX products. I personally have never heard of SimAir until now. Which goes to show that development has not been progressed well.
A little bit of background info on what SimAir is, since there has been very little info released lately. SimAir is similar to what FSPassengers is, but is much more complex then just creating an airline and flying. The way REX is describing this, makes it sound like a multiplayer online game where you compete against other pilots. You can create your own airline, whether that be a major world-wide airline, a small regional airline, or cargo operations. You can also hire, or be hired by other users to fly for their airline. Much like a virtual airline.
If you would like to checkout a full and detailed list of what SimAir is and how it can impact your simulation experience, the REX website will give you all the information you need. REX stated that there will be another update regarding SimAir on Monday, November 26th, 2018. If you want to be there for when this update is released, it will be available on the REX forums.
