Not to mention my company line check in the Embraer 145 I fly for Envoy (American Airlines little regional brother) keeps my helicopter ATP current as the fixed wing and helicopter atp is considered the same certificate number.
There are some helicopter specific recencies for flying IFR etc but the overarching certificate can be kept alive by my airline job in FAA land.
I came to the US from Australia (Australia being similar to the U.K. With regard to helicopter types and renewals etc). There was theoretically nothing stopping me jumping in a 109 (private ops or part 61 not part 135) having never flown one before With most of my helicopter time being b412 (also doesn't require a type rating in the US being under 12,500 lbs).
