I am a Realtor wanting to use drone aerial photography in my business but only if I can be 100% legal. I have already passed my 107 and obtained that license but I started chasing legality over a year ago before there was a 107 path. I applied for a section 333 exemption which got put on hold once 107 was announced. I went to the National Realtors Convention in San Diego in November of 2015. One of the the sessions was a panel of FAA representatives briefing us on these very laws with an extensive Q&A period. It was a large crowd and somewhat hostile as many were already using drones and being told they must stop. Several people actually challenged the FAA rep by saying somewhat the same things like "I'm not hurting anyone .... I don't think you have the legal authority .... You can't catch us all, you don't have the manpower .... etc." The FAA rep calmly explained that the fine process takes a long time, maybe a year or more and many were in process. He also said that although they don't necessarily go looking for violators, they DO respond to all complaints and turn ins. By turn in, I'm talking about those who go to all the time and expense to be legal having to compete with someone who is not legal. They can file that complaint and FAA will look into it, practically guaranteed. At least with the 333 Exemptions, the FAA actually listed those exemption holders on their web site along with a convenient online form to turn someone in. I expect they will list the 107 license holders as well. Like in my own case, I have spent hundreds of hours and thousands of dollars to use this in my business legally. It was done so that I would have a significant "point of difference" over my competitors. If, to compete with me, they run over to Best Buy, buy a drone, and post the pics of their listings, I WILL turn them in, I just will. I can see that happening with everyone trying to legally incorporate drone usage into ANY business. And, it was explained that actually receiving compensation is not a pre-requisite. Just using it to "enhance" a business qualifies as commercial. I'm not charging extra but I'm enhancing. A farmer looking at his crops is looking for drought, predator damage, disease ... he is enhancing his business. The "art' dealer throws a drone photograph into the mix in a street fair and that picture catches the eye of the passer by more so than the rest ... he just enhanced his business. In reality, we mostly all know the difference between hobby flying and any kind of non-hobby flying but many try to ft into a gray area so that they don't have to get the license. I personally feel that air space is air space and that, eventually, everyone, hobbyists included, will require a license to fly a drone. We will do that to ourselves. As a practical matter, it's the only way to stop the arguments and disagreements.
