There was a time when it was possible to have an ATP License for Rotocraft in the USA that was limited to VFR.
That has gone by the boards and now the ATP License requires the Intrument portion as an integral part of the License.
We do have a Commercial Licence and a separate Instrument rating but the ATP includes the equivalent of the instrument rating.
The end result is the same as in the UK.
We view “Type Ratings” very differently than does the UK.
We don’t have as many bureaucrats to feed as ya’ll do......yet!
