This just like me. As a covid lockdown project I remodelled the office, purchased top of the range Monitor, OS and control devices. ( at least as much as I could, everybody was at it it and most of the well reviewed items were sold out all over the place or had ridiculous prices ).
I was pretty confident that I would soon be proficient as I had used the FS X version many years ago.
BIG MISTAKE.
MS2020 is NOTHING like anything you have experienced before. Start again with the FSX version and learn your trade.
The Training is better, but the scenery is not so good. If you are learning how to fly, the only scenery you will be interested in is the hills!
MS20 is breathtaking, especially on my Samsung curved 49" monitor. However it is better to be prepared for some longer distance viewing otherwise your head will swivel off.
The next issue is probably the most serious at the start. Downloading.
Even at my high spec and half decent down load speed, you are looking at 112 Gb and 6 hours to get it on the machine. IN addition, that is not all of it. You have further options to load up a whole load more, but be patient and leave everything else for the time you are confident with the system. The latest updates that you are offered AND more are offered every time you log on, take up a really long time to load which does destroy the need to just get it on and start flying.
A third issue, at least for me, is the mysterious failure of a chosen situation or play to perform correctly. In the absence of a manual, (and this will be a MASSIVE excersise), the best advice I get from the experts on this forum, and it is the only one worth a light, is to reload the software.
WHAT!!!
Another 8 hours. But it works.
My advice is to familiarise your basic skills with FSX, avoid the training and dive into a few simple demonstrations of individual flights. They are beyond compare.
I believe that the management release of this application was rushed through for marketing reasons and the hope that we will all learn on the job. Now where have we all heard that before?
But I am now another junior newbie, so I can only say how my experience has been and I'm in my mid-eighties!
