I miss any helicopter missions in career mode (don’t have a company yet). The list of missions for the central Europe region only offers missions for fixed-wing aircraft, no mission for helicopters e.g. with Cabri G2.
I have CPL Rotorcraft with specialization “Passenger Transport and Flightseeing” (level 81)
I have opened up quite some parts of Europe, Middle East and US and there are (a view) heli missions - but not nearly as much as fixed wings. Must be another of the many bugs.
