FWIW, I own 3 drones and have a Part 107 FAA license. I've been flying for 5-6 years.
So, I thought to myself "You know, a drone could be a really great tool in a SHTF situation."
Let's discuss what a drone might be good for.
The first thing I thought of was recon from the safety of your home...
Drones have a lot of useful applications.
Drones are pretty cool and they could definitely be useful for gaining intel. It may not take as much commitment to get enough proficiency to be useful, compared to other hobbies, but I think my wife would kill me if I started spending money on yet another thing, lol.
Drones do take some training and practice. Easy to fly. Easy to crash. It is important to know the basic rules and laws of the skies. In the past few years the FAA came out with the Recreational UAS Safety Test (TRUST test). Even part 107 pilots are supposed to take this. I did it in the car on vacation and it took less than 10 minutes, but I think useful for new drone owners/pilots.
When SHTF there are no laws protecting drones and they might become easy targets.
I do have to wonder how many people would notice them though. How far away can you hear the noise, like 200 feet?
Interesting thought. Charging it may become an issue. I guess it depends how much S hits the F.
1) modern drones tend to be small, not much larger than a clay shotgun target. I think it would be very difficult to shoot down with a pistol. I'm not hands-on familiar with shotguns and effective range of the ammo. But I would suspect that a drone a few hundred feet out would be difficult to take down. Additionally, anyone who shoots down a drone will have committed a felony. One hard rule is that the FAA owns the airspace from 1 foot above the ground to infinity. While there are restricted areas, much of the legality of flying over areas is determined by the launch and land position, not where the drone may be flying at any given moment. If the drone crashed in the restricted area, having been launched from a legal spot... Well... there may be issues recovering your drone.
EDIT: If you own a DJI drone, they have a process and monitoring system called "geofencing". Geofencing will lock your drone out of certain areas and it will be like hitting a wall. IMO it is a bit of overkill, big brother and sometimes a pain to get past even though the airspace is not restricted. When I do commercial shoots I always survey the DJI geofencing online, apply to have it modified then will go to the site and test to make sure they have unlocked the area. Often times DJI does not do it properly. I have stories to tell about this.
Interestingly there are blanket restrictions in what are designated as "sensitive areas" . Then entire of Washington DC is a "no fly" zone. You can't even fly in your back yard at any altitude. We have kids in DC and I don't even bring my drone when we visit. I have to wonder what was required to get permission for B roll (or just a few minutes of skirting the rule) of the city for TV shows and films?
2) How far can you hear a drone? It depends on the drone. My smaller drones cannot be heard by me until they are almost right on top of me. You are more apt to SEE my drones before you hear them because I always fly with strobes, even though strobes are only required at night. The furthest I have been able to spot my larger drone is about 10,000 ft over water with multiple strobes blinking. I do not rely on my video monitor/phone/tablet and try my best to stay within visual line of sight.
Side note: Some people get apoplectic when they see or suspect a drone is near. For the most part, camera drones are equipped with WIDE ANGLE lenses, so "spying" accusations are often absurd. Sometimes a little bit nuts. A few years back I ws flying over acres of farmland in Vermont, flying toward a mountain off my children's back porch, facing open fields. My step-son got a call from a neighbor saying "we got a drone flying around. What are we going to do?" Of course he spotted my drone with the strobes blaring, not any closer than 1000 feet from where he possibly could have been. When filming buildings or private property specifically I always contact the owner/management to get permission to fly over the property and film it. I do not contact property owners for "transitional" over-flights. It isn't required and IMO unnecessary. It's all about practicality and courtesy. More to say, but I'll stop here.
3) Charging. There are multiple charging systems, some very efficient to get drone batteries charged from your car's 12v plugs. Most drone owners purchase multiple batteries as a typical flight of 20-30 minutes would be considered standard on a single battery, though the industry has been pushing for longer and longer flying times per battery.
