Hi again,
In my personal opinion i think that Euroharmony should have a timetable for helicopters.
About the sceneries, there isn't any need to have special sceneries, because if we use helicopters that can move (on ground), then they must follow the ground rules of any aircraft. That means, they should go via the taxiway to the runway and then take-off (of course more vertically than the planes

).
The landing mode is done again on the landing runway, and after that, we move the heli to the taxiway for gates (or heli gate).
In a first approach, we could create just 10 flights per Hub just to get the feeling about how many pilots would try to fly them... Regional Flights.
If we look that there are many PIREP's about it, then we improve and upgrade our timetable, and, if a near future grab one or two more helis to our fleet

.
Of course this is just a personal thought... nothing more than that.
Regards,
