If you get an ATP in a single, you are only able to use your ATP priviledges in a single, which makes it basically a worthless rating. I am not aware of a single engine aircraft out there that requires an ATP.
If you get an ATP in a multi, you are only able to use your ATP privledges in a multi.
Your certificate says: ATP AMEL. Commercial Priviledges ASEL.
