The plane spawns at the edge of the island and despawns there too.
Often players wonder why the plane just appeared/disappeared right over them.
To make this more immersive, is there an option to let the plane spawn further out?
If it's there I didn't see it.

Dont you use the broadcast features which not only tell when its going to come, when it lands and where it landed ?
You could also use the "incoming" plugin which tells you what direction it is coming from,
