It does not matter which SIM you want to place a static object in there are a couple of ways you can do this.
One way you might be to create a AI flight plan that does not have a departure time. I am not sure if this will work or not
The other way is you will need to have a BGL COMPILER and there is one inside the FS SDK folder
You basically have to create a small scenery area consisting of the static object. Hangers and other airport buildings can be created using AFCAD for FS9 and below and Airport Design Editor for FSX
The hardest part of this process is you have to know the Longitude & Latitude to place the object and than you have to make sure there is nothing in that spot. You do that by using flatten commands and exclude commands.
Using these commands can be tricky. If you do not know what you are doing you can create some strange things like a huge hole in the middle of know where or a building with a hole in it.

There are programs out there that you can use to create all kinds of static objects one such program is called GMAX but I have to caution you this is not what you would call a user friendly software.
I used it and was able to create a line shack which I now use inside of my home airport KJAX. But it was not the easiest thing to do it depends on what you know about programs like GMAX.
I tried to recreate an airplane as there was a tutorial for it and went nearly bald in the process as no matter what i did I just could not get the shape they wanted me to create.
This program uses polygons and you have to stretch them in ways you can not imagine. It takes a ton of patience.
One reason my hat is off to people that do this and make it look so easy. Trust me it is not.!
