So far, I have only been watching this site as I am a rank beginner when it comes to flying drones, but commercially licensed in rotorcraft - helicopter, with ASEL private privileges. I flew helicopters in 'Nam and am very excited to get into drones.
Since I also live in a rural setting, with questionable neighbors, I have hesitated flying one over my property - or in my area. Although I have had my Phantom 3 Pro from the time it came out, I have yet to fly it - partly because of the reason behind the current post and also because a lot of bad press was coming out then about drones and how people were flying them. (I was also ill, but that's another story. )
So, the excitement is back, but also the apprehension of dealing with angry onlookers. After a career in the psychology field, I developed an interest in why some people would be so hostile toward drones - both out of curiosity and to develop a strategy in the event of confrontation.
First, it's not likely we are even likely to do real damage with our little aircraft, unless we fly them into full scale aircraft. Folks can also get really pissed when full-sized helicopters are landed in their neighborhood. I'll never forget that old papasan in Vietnam who got so angry when we kept blowing his grass-roof shed over as we landed in the adjacent field to work on building a village school house.
But here are some hopeful solutions I think might help help reduce the chance of altercations and/or loss of your drone by shoot down.
First, as others have said, it's a federal offense to shoot down an aircraft - and that includes drones. That word needs to get out to as many people as possible. I have been delighted that, when the FAA rules complexities dust finally settled, both drones and their pilots have been fully accepted into the aviation community. So, first, it helps us to present ourselves in as responsible and even professional way as possible.
This approach should reduce the likelihood of conflict while flying. Watching YouTube videos, I have noticed that confrontations seem to typically involve some older busybody confronting a young drone flyer who is actually minding his own business. In these cases, the pilot was dressed very casually and his activities also appeared casually-driven - as it was his right to be that way. But, I think it is the combination of youth and carefree, casual presentation that invites older, technology-fearing bully-types to intrude on a nice day of flying.
So, there are some things we can do to reduce the chance of possible conflict.
First, it helps to present ourselves as professionally as possible when we are flying - even if it's only to wear an official- looking vest over whatever else we put on. The FAA is now encouraging the use of boldly colored, reflective safety vests to ward off those who would distract us from piloting, and thus would create a potentially dangerous situation. These vests, and signs, are available through Amazon and other vendors.
I am studying to get my commercial drone license (no small feat! ) and have been kitting up my gear to include labeled vests, warning signs, small safety cones, etc., that convey an official "Do not distract the pilot" theme. Beyond the FAA encouraging this, setting the flight staging area conveys a respect and recognition of the serious responsibility of flying - even if we are doing it for pure enjoyment. Also, any sense of officiality wards off the cops, for the most part - especially if you have your certificate.
Finally, some thoughts if anybody actually wants to shoot down your drone. In Vietnam, most of our flying was either "on the deck" or over small arms range (as I recall, about 1200 AGL). Now, that's not actual range, but what experience taught us is a safer altitude due to difficulty of small arms fire actually targeting and hitting the aircraft. I can tell you they didn't always miss, but we established that as a "safe" standard in our unit.
How would that translate in drone flying? If we translate that to scale altitudes, given the relative small size of drones, maintaining that 300 foot minimum altitude, when flying over possibly hostile territory, should significantly reduce the chances of being hit by ground fire. Rifles are not that accurate, in general, against a flying, moving, target. Shotguns may pose a higher threat - especially at a lower altitude.
There are some evasive maneuvers you can employ, in the event your drone becomes a target. You are hoping the first shot misses... it's always the first shot most likely to get you... Or, you spot somebody aiming at your drone. Any sudden maneuver will throw aim off, but it is especially difficult to accurately paint a rapidly-rising target. In such a situation, I would climb to maximum altitude as quickly as possible, spiraling if it doesn't compromise altitude gain, then hit the return home button. If possible, have your partner record the incident on cell phone. Zig-zagging can help after that, but don't do it in a consistent pattern.
By the way, watching some of those kids get undeserved tongue-lashings for simply flying their drones in the proximity of bullies has been something of an inspiration for me because of their forbearance and politeness. I'm not sure I could be so polite in the face of the tongue lashings I saw in the videos!
I hope your neighbor will come to her senses and leave you to your flying. Btw, you might try wearing your old Air Force hat when you do. She might respect your service, but if she doesn't and she is paranoid-enough, she might wonder if your drone could be a threat and leave you alone!
Sorry for the long post! I am learning a lot from you guys and saw an opportunity to maybe give back a little.
