Hey, my friend… I share your frustration, but from a commercial perspective, this is how it must be for now.
Consider this… MS markets and sells MSFS and features a beautiful C700 Longitude with a modern G5000 showing embedded charts. Some individual out there sees that native implementation of charts in the G5000 then spends their good money to purchase MSFS Deluxe.
Now, after they’ve been enjoying it for some time, Navigraph goes out of business and the charts go away. What is MS to do? They marketed an avionics suite with embedded charts and now their default product doesn’t work as advertised. They are not willing to take that chance, and again, I get it. MS need a solution where they can ensure the “thing” they sell works like the “thing” they advertised. It really is as simple as that.
And rather than thinking MS “mucked this up”, they made a business decision to add a 3rd party developer to their team to provide a significant improvement to their default aircraft. They have enhanced the MSFS SKU. I can’t blame them for that because it sure has made the Longitude (and the other affected aircraft) much more enjoyable (immersive) to fly.
We shall see what the future brings, but until then, I am enjoying the Longitude immensely with Navigraph charts sitting pretty on my second monitor. Blue skies, my friend.
