Dude, you are completely clueless. The only Restricted Areas are Military. Other areas can be designated as a TFR (Temporary Flight Restriction) which has its own guidelines based on the need. Some are completely restricted like one for POTUS. (President of the United States) or a minor restriction for a forrest fire or NASCAR race. There are a couple of more areas where special rules are in place, such as the Grand Canyon, certain Wilderness Areas etc.. So, the helicopter was NOT in a restricted area. Get it????
Secondly, I've already explained that 75 feet over the ground is not in itself dangerous. Have you ever been in a helicopter or have any idea what you are talking about? Never mind, you've already answered that.
National parks and forest are a type of restricted area, not restricted airspace. Perhaps I should not have said restricted area but I meant any airspace that has restrictions. She did not say if the park was a federal park or not. And yes flying a helicopter at full speed 75 feet over the ground is considered unsafe, this unofficial incident is proof of that. Flying a helicopter at that height at a low speed which of course they are capable of is not.
But, the model must always yield to the manned aircraft. ALWAYS, NO EXCEPTIONS. Now lets move on. Give this a rest, it is done and horse is getting beat over and over again.
I agree, but the term used in the AC and AMA rules is to give right of way. That to me does not mean that you yield unless it is obvious that you are going to cross flight paths. I do not think any model airplane pilot can be clear of that with our ground perspective, unless on opposite sides of the field, or if the full scale aircraft is well clear above the model airfield.
