The new laws are asking for both the Captain and the co-pilot to both be ATP rated, due to the A/C being a single crew operation.
The reason behind this, is that, as it being a single crew operation, each pilot that poles, becomes the Captain on their leg, thus now neccessitating for both to be ATP rated, as the Captain has to be ATP rated.
Now does that answer peoples questions.
