“The Standard Edition will cost $59.99, and will let you fly 20 different planes, and land (and takeoff) from 30 different airports. The Deluxe Edition ($89.99) will include 25 aircraft and 35 airports, and the Premium Deluxe Edition ($119.99) will include 35 aircraft and 35 airports.”
You can actually fly to every single airport in the world, (takeoff and land). There are even 37,000 of the world airports that have been manually edited so that they are more detailed/realistic. These 30 (standard), 35 (deluxe), and 40 (premium edition) airports are just handcrafted international airports that are even more detailed than all of the others. The standard edition will still have these same 15 airports as the premium edition does, but they just won’t be the more detailed/realistic versions .
The new 'sensitivity' setting in the last 2 MSFS updates which allow cutting off the ends of extreme controller position allows better control of the Deluxe and Premium aircraft.
This was an issue because while the Standard planes had flight_model.cfg files that you could modify the 'effectiveness' of your controllers. But the Deluxe and Premium planes had these files hidden (in code).
But now the new sensitivity settings in MSFS itself (Controls window) allow controlling the effectiveness not just sensitivity, one place for all planes, much easier. And it works on all Standard, Deluxe, Premium, and all 3rd party planes.
If you need more than one adjustment because a particular plane needs a different setting, just save a new profile with a name that reminds you it is for only a certain plane (or planes).
This makes the Deluxe and Premium editions much more valuable now because those planes will be as easy to set to fly as are the Standard edition planes.
