Why We Need Certain Consumer Drone Regulations 176

stowie writes: In the last week, state and federal firefighters have fought more than 270 wildfires in California. Here's the problem: firefighters are seeing more unauthorized consumer drones flying over active wildfires. Maybe the drone owners don't know or maybe they don't care, but temporary flight restrictions are placed over wildfire areas due to the aircraft used to help contain the fires. The aircraft used to knock down flames and survey burn areas have to cease operations when there is a drone in the air.

      Let them clear the airspace.

      No, the FAA should have clear authority in clearing the airspace. The FAA should regulate drones as any other aircraft, and make a clear distinction between a "drone" and an RC toy.

      That means that drone operators must comply with FAA rules, check weather briefings and NOTAMs before every flight and stay the F out of a TFR.

        The FAA already has that authority. People are ignoring the rules, or just aren't aware of them. This not evidence that we need more regulations.

          People are ignoring the rules, or just aren't aware of them. This not evidence that we need more regulations.

          The FAA has authority to create rules, but the current set of rules need to be applied to newer technology. In short, the rules are limited to:

          restricting operations to 400 feet above the surface; requiring that the devices give right of way to, and avoid flying near manned aircraft; and using observers to assist in operations;

          (source: https://www.faa.gov/uas/media/... [faa.gov])

        Birds don't comply with FAA rules... and it's not inconceivable that one to have a drone that looks like a bird from a distance.

        Of course, then you might also risk having it shot down anyways...

        But what happens when technology gets to the point that you can make a drone that believably (to a human being on the ground) looks like a protected species of bird?

        • Birds don't contain carbon fibre, metal and volatile batteries.

          Aircraft are designed to survive hitting and/or ingesting birds.

          • And yet so many aircraft are downed or seriously damaged by bird strikes. When it hits the right place, even a small bird can mess up a plane, and when you are in such a seriously dangerous area with unpredictable air currents such as near a wildfire, you really can risk that.
            Now just in case anyone out there isn't clear, a drone is a lot more dangerous to hit than most birds due to mass and strength of many components.
            Also, if you are so unworried about birds, you should wonder why airports spend so much
            • Bird's also don't generally like flying above a fire.
              It's hot and there is a bunch of toxic smoke.

              Birds hitting planes don't destroy planes. They cost a lot of money to repair though, hence effort and money spend to keep them (and animal rights groups) away.

      Given the fairly limited range of the radios used to control said drones, why not just arrest and jail the idiot who is operating the drone for hindering active firefighting operations? Even better, fine the dummy for any costs associated with an aborted retardant run (ever price-out jet fuel? charge 'em that for a few aborted runs and I bet that no one else would even want to try.) The authorities usually cordon off a *huge* zone around an active fire (especially areas in its projected path) with mandatory evacuation orders, and further orders to bodily remove anyone dumb enough to be within that zone. They emphatically do not screw around with this... which leads me to wonder who would be dumb enough to risk the ire of authorities and property owners by pulling such a stupid stunt.

      ** Yes, I know what a defensible zone is and I fully do my best to insure one around the homestead. I also sit down with my wife and audit/arrange things every spring (sometime before fire season) to insure that an evacuation order means that either one of us can grab the important/critical shit (and the dogs), and get out of Dodge within five minutes, maximum. It's a good practice to have if you live in a forested wilderness, truth be told.

    Or, just shoot the drone down. You probably wouldn't even need firearms -- maybe some kind of EMP pulse and let the drone fall into the fire. Or a non-lethal shotgun round designed to take out propellers. (Say, a big tangle if nylon fishing line.)

    The thing is, as a drone pilot, if I see a fire, the last thing I want to do is get in the way of firefighters and/or emergency services. That's inexcusable. But to the extent it doesn't interfere, I'd sure love to get some footage. It might even be useful later. I wonder if there's some kind of compromise. Like, drones can scout out the situation until aircraft are deployed, and then must leave the area or risk destruction and/or heavy fines.

        "heavy fines" how ....national drone registry?

        Manned aircraft have to carry transponders and broadcast their license code. It's not unreasonable that "drones" (etc.) which can reasonably easily interfere with aircraft (anything with more than 500' of range might be one possible criteria) should carry a low-power transponder which can be used to ID them. It could work like active RFID, and only broadcast when ID is requested.

        • Manned aircraft have to carry transponders and broadcast their license code.

          In SOME airspace SOME aircraft have to carry transponders that TRANSPOND to radar interrogation with the code assigned by ATC. It's not a broadcast, it's not a "license code", it's not associated with any specific aircraft until ATC assigns it.

            That sounds like a great system. If you want to fly your drone in controlled airspace, then you should have to have something like that on it.

            • That sounds like a great system. If you want to fly your drone in controlled airspace, then you should have to have something like that on it.

              Nonsense. You shouldn't be in a place where you endanger manned aircraft in the first place.

              In the second place, that system depends on ATC providing traffic separation services to the manned aircraft, which they do not do for VFR flights.

              Third, it depends on the pilot actually seeing the target to avoid it. Smokey air, turbulence, pilot busy flying and looking for the drop site, not a very good recipe for seeing a small drone before it hits you.

A drone is going to go tits up rapidly in any updraft. After you lose your thousand dollar toy you might think of a less expensive stupid hobby next time - like buying a boat.

          A drone sitting over the firefighters or behind them is going to be completely out of the flight line. No danger to anybody since all of the firefighters are wearing hard hats anyway.

          And hopefully, the pros with the $20 000 drones that have the range and altitude to get in the way are smart enough to read the NOTAMs and have some common sense. Yes, there will be exceptions, but you can't make stupid illegal. Adding more anti stupid regulations is rarely successful.

            Firefighting aircraft do not appear magically directly over a fire and then magically disappear after dumping their loads. They have to get from the landing area to the fire and then back again. As a drone operator, you have NO IDEA what the flight path of the firefighting aircraft will be since they have to consider weather and winds and desired destinations in their planning.

            And it's not a "flight line" -- that's the place where the airplanes park.

            Yes, there will be exceptions, but you can't make stupid illegal.

            You can make "dangerous" illegal. And putting an aircraft into a no-fly zone just to take pictures is not just stupid, it is dangerous -- which is why they put temporary flight restrictions over active fires in the first place.

  • This is crazy. http://www.liveleak.com/view?i... [liveleak.com] (OK, its fake... but won't be long until one gets sucked into an engine.)
  • There's something to be said about introducing new regulations because people are ignoring the existing regulations. Like making weapons illegal because people use them for murder.

      The first question ones should ask is not "is the current regulation failing ?", but "what was the reason of the current regulation ?".
  • The worst part is the drones can actually make the life of firefighters easier by providing them with a better situational awareness... but no, let's keep doing it as was done since the 16th century, because hey, we're afraid to change.
    • Some idiot flying a drone into a fire zone isn't going to help the firefighters. Even if said idiot shares his or her footage, it's probably in an area the firefighters didn't need information on. A drone directed by the firefighters might be very useful. Similarly, firefighters may have aircraft laden with fire retardant flying in the restricted area, but that doesn't mean we should allow random private aircraft.

  • I'm gonna make a guess at the current regulation's reason: it has nothing to do about firefighting, and more to do about smoke being detrimental to proper engine function and airplane control. A similar temporary regulation was put in place over Europe during a volcanic eruption in Island (if my memory serves me well).
  • The FAA Mimimum Safe Altitude is 1000' so we limit consumer drones to 500'. This solves 90% of the problems. We prohibit use of any drones within 3 miles of controlled airspace at airports.

    At wildfires simplly allow police and firefighters involved aircraft operations only, to use highpower frequency jammers when the aircraft are within 3 miles of their position. Then you require any drones that lose control signals to automatically land safely.

    If their drone was over the fire and they lose it then that is

  • For the sake of it, if you can fly a Predator on the other side of the earth to send HellFire missile to kill people, how hard can it be to have a few remote operated drone to put fire out ?

    Oh, wait, it already exist... http://www.kaman.com/aerospace... [kaman.com]

    But I guess people prefer to have their taxes go to war machine to kill other people of a different culture, rather than real public safety machines which would make a change...
  • Yeah it's like this. Until physics prevents a flying drone that fails or is interfered with from following Newton's Laws, drones are too dangerous to be flying over populated areas.

    Even "failsafe" parachutes only slow the descent of the 100lb mechanical thing landing on the pedestrian, window, moving car, bridge, darkened road, power line, etc. etc. et fucking cetera.

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
