As explained many times on the forum, we don't use the default small/medium/large gate designation, so we can get rid of the default ground vehicles. A method shared by many other developers too.
But on our sceneries, you can ignore the default "Go To Aiport" menu (which would be the only case when not having the gate labeled would make difficult to decide where to park), and use GSX instead, which allows to list gates in a way more realistic way, with their real world names.
Call the GSX menu when outside of a parking (for example, on the runway) and select "Just warp me there". This will basically replace the default "Go To Airport" menu.
