I was wondering, do VFR flights not give your vectors and directions to the arriving airport?  Also, I'm having trouble with add-on scenery.  I did one for YVVR, and it put only the jetways on.  It had them scattered all over the airport!  Some on runways, etc.  Only 2 attatached to the terminal.  Anyone?

Ok, anyone for the other question?  Also, where do I put misc downloads like ground trucks, etc.

Things like ground trucks are usually elements that you'd use when making your own scenery. They're not generally something you could just drop ito a folder and expect to subsequently see.

You'd need to design scenery that included them and inport the scenery itself.

In technical terms? You use SCASM code to create an object that you texture and place in the sim with a scenery design utility, LOL Not real technical, but you get the point. there are a few programs that help you design Macros (objects) EOD (easy object designer), NOVA, FSDS, GMAX (hardest, but best results) then you use a scenery design utility such as Airport or FSSC to create an overview of the location you are working on and then place the objects how you want, with other options as well.
It can be as simple as adding a house to an area to reworking the terrain code to allow for new roads and rivers, just depends on how much you want to put into it.

Hope that helps
