Tell MSFS to Not Spawn an Aircraft at a Specific Spot?

I’m no aviation expert, but I’m thinking that this is not an ideal situation (for the small plane, anyway):

I made a change in the SDK to an airport to add the SW aircraft, but sometimes MSFS adds a plane there. I want to use Real-Time Online traffic if I can. Is there some way in the SDK to prevent this? I’m guessing the answer is no, but it doesn’t hurt to ask.

If your plane is static then dont put a parking postion there, just put the planes without them. Will that work?

I’ve just recently started using Airport Design Editor and never thought to try that. I’m sure that’ll work! Thanks very much for the suggestion.
