I'm a total newbie to MFS. I don't even own a version yet(still researching FS9 & FSX).

If I add the Tahiti X expansion(or any expansion) will it be there when I fly to it, or do I have to start from one of the local airports?

For example, if I fly a jumbojet there, will I see the expansion, or will I see the default land that comes with FSX?

The reason I ask is, in the #59 issue of PC Pilot, in the review it says, "The area covered is an enormous two-and-a-half million kilometers, so your choice of aircraft is important."

Also, is there something I can read that explains add-ons(planes, scenery, missions, etc...) in MSFS 9 or X and how they are implemented by the sim?

TIA,

Cliff

Tahiti X is like every other scenery addon. Once it is installed, it will show up whether you start at one of the island airports or fly in from a thousand miles away.
