I realize this is old fashioned...but both types of aircraft should show respect and courtesy to one another.
Helicopter pilots should remember the effects of their rotor wash and airplane pilots should understand the risks of that to their aircraft.
Giving way....using commonsense....to afford the maximum amount of safety to the other aircraft is not a bad thing.
Also, a very good idea is to actually study the Right of Way Rules and understand them....along with sharing a coffee with pilots of other types of aircraft and learn about them and how they go about their business.
One thing for sure....if you taxi in your small airplane underneath a hovering helicopter...especially one of some size....you will get one very quick lesson in physics, aerodynamics, and emergency medicine.
