Regardless, an airplane has right-of-way over a helicopter. This is drilled into helicopter pilots from day 1.
That was never drillled into me during my career. What is drilled into all pilots regardless of airframe is to be responsible for the safe and orderly conduct of the flight. If on an IFR flight plan, fly the plan, check in with ATC, follow instructions and practice good see and avoid techniques. If on a VFR plan, fly the plan, check in with ATC, follow instructions and practice good see and avoid techniques. ATC will prioritize IFR flights over VFR flights, but will treat each flight with the same precautions.
