This has been an interesting thread to read as it has evolved a little over the last year. I have been needing some definitive answers to this problem due to my involvement in public safety. To that end, I want to add (in an edifying way if I may) some considerations to the issue of using a handheld radio.
If some of you don't have time to read this thread, I suggest you read this article posted. It is helpful and may give you some thoughts on how and why one might have a handheld radio as a part 107 pilot.
Drone pilots should have an aviation handheld radio to communicate with nearby aircraft, transmit blind announcements about operations near an uncontrolled airport, and most importantly, to communicate with helicopters flying above incident scenes. I regularly communicate with news helicopters...
psflight.org
My background....Part 61 pilot with instrument endorsement, Part 107 Pilot, Amateur Radio License (General Class), GMRS, and RR License with FCC.
So, the real issue. A key significant emphasis of radio use for any pilot is communication of intention and situational awareness. Yes, there are defined zones and airspaces which means in an ideal world, there should be no reason for communication at all. But ideal and humans are a bit of an oxymoron. I have in my years nearly been hit by planes squeaking into a pattern where they shouldn't be and they never announced intention. I live in a remote part of my state and my house routinely gets flown over by a helicopter pilot at about 350 ft AGL because he thinks it's fun. So.....would making an announcement for situational awareness be valuable? Well as an "ounce of prevention" kind of guy I think it would help. I'd rather tell that knucklehead to stay clear rather than scrape his wreckage off my driveway. Let me use another example. I often used to fly in and out of an airport that had parachutes. Every time they threw humans out of a perfectly good aircraft, they'd announce "jumpers" so we could watch out for them. I often mused over what I was supposed to do with that information. If one smashed into my windshield, I'm not sure I could do anything to avoid it....but no pilot would say that the announcement was frivolous or should be banned from the airwaves. So why not a courteous single positional announcement that you are operating, location, and altitude? I think that's not such a bad idea if you are within 5 miles of an airport. But that's just me.
So, I applaud the FAA in their attempts to create a safe sky environment. Now the reality of FAA meets FCC and the implications. The aviation licenses in the continental US are collocated to a physical aircraft which means the FCC has waived the need for a pilot to hold a radio license. As some of you have commented on talking to towers or even the FCC, the answers and mystery shouldn't surprise anyone. Appropriate judicious use of aviation frequencies has a benefit but consider what would happen if the FAA or FCC told every part 107 pilot they needed to do it. You'd have every person and their dog chatting up the CTAF and UNICOM bands and really creating a safety problem. Yet....if you are truly a part 61 pilot, you have to admit, there are people out there who do not follow the rules with altitudes. So, is a handheld a good idea for general broadcast if you are in an airport vicinity. I think so. Can you legally transmit on one? Well guess what, there may actually be a bit of a loophole on that. If you read the article I attached, a pilot may use a portable radio to transmit if he is inside his own aircraft. That is the verbiage quoted in this thread that most part 61 pilots are familiar with. But what most forget is that the United States has deviated slightly from international rule. Pilots in international countries must also possess a radio license. The FCC equivalent to the is the Restricted Operational License. (RR Class). This allows the user to operate on aviation bands and if you look at FCC form 605 part C, it does have a section for a "portable radio."
Now here is what is NOT clear by the FCC. They clearly state that if you operate within the US, you "are not required to have a restricted operational license." This phraseology, however, is NOT equivalent to saying, " you cannot use one." Hence a federal loophole unless there is a legal eagle out there that can fill in something I haven't found.
So why would the FCC leave this open? Who knows. Maybe they and the FAA realize there is occasional benefit to transmitting on an aviation band while you are on the ground. But (and I agree with them on this) don't want to open a flood gate to inappropriate use of bandwidth by people who are not familiar with aviation communication.
I don't think this thread should become old or archived. I think more should happen here. The LAANC system gives permission to fly. But not everyone winds up where they are supposed to be. So....maybe the FAA and FCC should consider allowing a restricted operational license within the United States for such purposes.
Again, I suggest you read the article written above and consider it in this discussion.
