It’s wild how helicopters are allowed to operate in US. We were in NZ in November and it’s totally different there.
We had a helicopter deliver us from Waiheke to Auckland FBO for a private jet transfer further. When the helicopter approaches the airport, it goes into a holding pattern adjacent to the landing path. From there, the ATC gives the helicopter pilot permission to join the landing path between airplanes. The helicopter enters the landing path to approach the airport, and then follows the taxiways out of the runway all the way to the FBO.
Seemed like excessive precaution then but now I can see how it makes sense.
Applied to this case, you would simply need to have the helicopter hold until given permission to cross the landing path, it’s the easiest thing really.
