content: For nearly 24h a pair of drones have closed Gatwick, Britan's second busiest, airport and now the army have been called in to assist.https://www.bbc.co.uk/news/uk-england-sussex-46640033On the face of it, it looks like the authorities havn't used any counter measures to capture or disable the drones and maybe there is nothing available at short notice or more likely they are trying to locate the drone pilot or pilots. Perhaps the army have some DF gear that could be employed to narrow down the search area(s) to locate the drone pilot or pilots.The chaos caused at one of the busiest times of year highlights a lot of shortcommings in both legislation, drone countermeasures and the airlines complete inability to fly passengers to or from other airports.There has been some speculation that these could be larger than normal drones because they've managed to stay in the air for quite some and it's quite likely that they've been modified in some way. At present you can't fly a drone within 1km of an airport perimeter but the airline pilots association and NATS have recomended a 5km exclusion zone which the goverment ignored. Airport authorities have seemingly done bugger all when it comes to drone countermeasures so this is a wake up call as it was bound to happen sooner or later.I'm not against flying drones or model aircraft and I would expect 99.9% of drone or model aircraft pilots use common sense and fly safely. However, as a drone pilot tweeted to the BBC, it costs up to £1000 for a three day training course before you can be certified, who is going spend £1000 when you can buy a drone for £50.There could be several drones and pilots involved and a lot of reporting is probably speculation, we won't know until the drone pilot or pilots are caught.

content: Please, don't call them drones, it's quad-copters.Seems like pretty well planed sabotage. It's not hobbyists doing this as a prank. If they didn't use model helicopters they would have used something else so I don't see why they should punish model aircraft hobbyists. Is there even any evidence there is someone actively controlling them? They could just be programmed to fly around randomly at Gatwick with the help of GPS.

For extra points, even charge themselves.Flightradar24 shows the ground vehicles have been running around like crazy

content: I see.My guess would be they are preprogrammed too, it seems way too risky to remote control them. The police might have some evidence they are not. If they are radio controlled you could jam the signal and disable them that way, unless they use some very fancy radio, so that would also suggest they are preprogrammed.

If it's say the Russians I doubt they'd want their actors to get caught (proper caught, not just identified like last time). The risk of this method seems huge. We could speculate how a sophisticated actor would do it in a low risk way, but I don't think it's a good idea.I fear technology will cause the end of freedom, cheap UAVs and biotech especially are making it possible for malcontents to cause mass harm in ways previously restricted to state actors (or at least very large cults).

Thanks for correcting me on that.QuoteQuoteGood comments from mikeselectricstuff and nali, they're probably autonomous to avoid radio detection and they might not be using GPS for navigation. They say it's not terrorism but it could be "economic terrorism" just look at how much economic damage has been done in one day, the final bill could run into millions for very little hardware cost. We've let the cat out of the bag and some very creative person or people have taken advantage.

content: QuoteThey used to use birds of prey, hawks I think, to scare off bird flocks and anyway they throw frozen chickens into aero enginges during the design phase in an effort to make them bird proof. EDIT: I think they defrost the chickens first otherwise it wouldn't be a valid test. Geese are probably some of the largest birds you might find in the UK or Europe but are they going to pose a potential threat at an airport, unlikely, but if you happen to hit a flock of geese mid flight then I think you might have problems. It's their airspace not ours, period. Common sense would dictate that you avoid flying into flocks of birds.

I am sure they have plenty of jamming technology available to protect heads of state against incoming missiles and radio controlled devices.3. Go get the nearest quad-copter FPV racing pilot, and he could very easily crash his quad-copter into the rouge drone. It is amazing what quad-copter racing pilots can do. Imagine the headlines: 'Quad-copter pilot saves the day for 100,000 stranded people'. The anti quad-copter biased media would shit their pants.

content: Quote from: apis on December 20, 2018, 08:38:19 pmYou will find that in most countries Drones be they fixed wing or Quadcopter styles are 'aircraft' under the local Air Navigation codes. As such Police under the law have limited power to fire on aircraft unless they pose a clear risk to humans and property to a lesser extent. Taking any ballistic approach to a drone in the air is potentially stupid as where does that projectile go when they miss and they will.Simply trying to dump a multi kg lump of anything from altitude using a random means of jamming has downsides too. Uncontrolled lumps kill too in particular around populated areas or crowds. Consider 4 or 5kg doing 80-100km/hr losing all control and drones get a lot heavier and faster. Protecting a military outpost from a strike is one thing but it is not a solution for all places or circumstances.Mid air collision as a response by another drone just not going to happen. By the time you get a competent person even in the air whatever was intended has been done and dusted even before the slim chance of getting that collision.The current 'geo fencing' technologies that a lot of the commercial drones come fitted with (one of mine has it) works really well as government can effectively block those drones being flown in any sensible manner.I am currently working on a design using off the shelf boards and components where there will be NO geofencing restrictions and the code is open sourced regardless. This is simple cheap and accessible to all.'But what if we block the GPS' - drones don't have to have GPS to fly. If you want to avoid most of the hitec counter measures and cause harm you don't use a quadcopter for a start you use an aircraft and minimise the metal and heat (easy to do) they fly longer faster and carry bigger payloads. Run redundant receivers and transmitters on very different parts of the spectrum and away you go and you FLY the drone/plane at your target. By the time an airport as in this case figured out you were coming you are already there.The Idiots of the world can't be stopped and a baseball bat to the head would only increase their IQ's. Those intent on causing harm or disruption will find a way around it as we have seen back into history not just recently. Fear mongering and media hype is not a solution either.

content: Quote from: borjam on December 21, 2018, 09:20:16 amTwo ways to do it:One is to train them to fly some distance above it and drop some kind of stringy thing or net. No danger to birds that way. Birds could be housed at the airport, and like carrier pigeons, trained not to bother planes and spring into action when an unauthorized drone was detected. (Carrier pigeons have a long history of service to mankind, even in wars, andin telecommunications, they always get through).Can be paid literally peanuts.In Australia and other warm weather areas (more and more as time goes on with global warming) parrots could be used.1.) Drawback - Too cheap + not high tech enough, so no money in it.2.) Birds too smart, might question official story.Alternative approach.:3.) fly another drone above the unauthorized drone and use that to deploy "nets". Or use some kind of automated cannon.4.) Drawback, might not be accurate enough. Could make up for accuracy with repeated firing.

content: maybe MI6 should spy on the anti drone defense manufacturers in case there is some SPECTRE shit going oni would spend the least amount of money possible to solve this problem. maybe unemployed trapeze artists with tennis rackets.maybe it would be cheaper to chase them down with some kinda flight/jet packs too then helicopters or other drones. i think if you double up every system, reduce flight time and deploy it out of a van that speeds up close you could make it safe and cheap, I think there is a kinda high performance/outdoors mentality with portable flight units, which is irrelevant to defending an airfield. they are pretty flat so you can drive a van to around where the problem is easily and have a non complicated flight path and reduce fuel costs and maintenance.Maybe simunitions or some kind of parachute laden cross bow bolt could be used that would be much safer then a rogue bullet (the bolt could deploy a parachute after it flies some distance and have a blunt tip suitable for smashing plastic but not going through someone if it hits em on the ground.or bird shot? if you can get close to it you can use bird shot which will be harmless and it could be made environmentally friendly with bismuth ammunition. If you get a guard to do it then you get rid of all the safety and ethics problems of giving a civilian authority a armed drone or having to resort to civilian/military cooperation or changing any laws etc because i don't think its illegal to discharge a firearm out of an air craft by an operator? you could even use civilian double barrel type shotguns so you don't need special weapons permits which I am pretty sure England is strict abound.

Despite theories about high tech detection and jamming, small drones are pretty much untraceable and the authorities will have no idea who is behind it.As usual, technology gets ways ahead of the ability of authorities to control it. Like script kiddies who can bring organizations to their knees with ransom-ware, now those so minded can do the same to airports. There will be some criminal organizations taking an interest, meanwhile government while enact sone strict but useless laws which only impact law abiding users.

A couple of years ago, there was an article (I have read it in dentists waiting rooms..) about how "drones from china" were spying on us to get "government secrets" from the publicIts amazing how divorced from reality that paper is. Whats worse is how anything to do with technology is almost instantly treated as magic by our government, with knee-jerk reactions to things (like banning all "psychoactive substances", or banning ALL encryption) just to be seen to be doing something - when in reality they are impotent by their own ignorance.I have no doubt this quad-copter saga will get lots of time in parliament, if anything, as a way to avoid talking about real issues, with lots of "we've set aside a task force and funding" even though it isn't required.Now we will have a wave of companies vying for government grants to tackle the "wide-spread drone problem". I'm seriously considering jumping on that bandwagon, seeing as how our government also purchased fake bomb detectors

I imagine that many less honourable people around the world are paying attention.I think the biggest risk to anyone flying a preprogrammed drone would be the forensic evidence left on the craft and the paper trail. You're bound to leave some traces on it and you need to take a number of precautions for it to not be traceable to your front door. They should be able to find you sooner or later, though the damage may already be done.

As on offensive weapon, I don't see the point. A drone would have the offensive capability of a mosquito compared to traditional military ordnance. For surveillance, I don't see a small drone having the range or the stealth to be useful. (Drones are pretty noisy.) If a drone is small and close like a quadcopter you can take it out with a shotgun. If a drone is large and far away like an ROV it will show up on radar and can be shot down by traditional means. There's no indication something large like an ROV was present near Gatwick.Realistically, for a quadcopter to shut down a major airport is just overreaction and the authorities are as much to blame as anyone.

Just simply not going to happen in any reliable form in particular if the drone is being flown by a pilot. Any chase drone needs to be better in flight than the target for a better chance of a catch or kill unless the drone pilot is stupid or doing you a favor by hovering waiting to be caught.The only real attack options are projectile (discussed heaps already and most projectiles are a bad idea in civilian areas) or electronic So Electronic detection and killing onboard electronics for domestic/public areas makes most sense.Before anyone says yeah but what about this one ....

content: Mr. Scram, I think I'm just being realistic.If you look at the most well informed writing on the current Brexit negotiations (with regard to the WTO in particular) the "survival" of commitments made by the UK as part of the EU and WTO are getting extensive discussion. They are being framed as a debt which the UK must in some way 'compensate' 'injured' nations for when they rejoin the WTO on their own. You can bet this 'compensation' is going to come in the form of jobs. At the same time the inflexible ideology of these little known deals is requiring the phasing out of safety net programs, because they have been reframed as temporary crutches, only to be kept while 'market based solutions' are worked out.Read up on the events of the last 25-30 years specifically how the so called "rules based trading system" works.

You can bet these people will feel the impact of these events for a while to come. History unfortunately shows that people can act very unreasonable towards people like these, even when it's blatantly clear they have nothing to do with it. Threats and actual violence aren't uncommon.

content: Something is fishy about this whole ordeal. Drone rules are EXTREMELY strict, at least here in Canada and also in the US, not sure about the UK. But some of the rules have very specific distances, like not being more than 75 meters from people, houses, roads etc or not going higher than 90m. They obviously need to have the technology to measure and track that if they're going to make those rules. I have a hard time believing that airports and authorities are not equipped to fully track a drone and the operator. They made the rules, they obviously will want to be able to enforce them. Tracking a drone operator would not even be that hard since RC controllers are ominidirectional, they could just triangulate and find the source of the controller signal. Or if they only want to take down the drone then they can just RF jam it or capture it with one of those drones that can throw a net.But all that said... now they're saying it was not even a drone? How can you go from "we saw a drone in the sky" to "there was nothing". Wonder if this is like the equivalent of a "bomb threat" where someone calls in false information and it was never even based on actual visual cues from the get go. Or is there more to it. I'm not one for conspiracies but something does seem fishy about this.Heck if you're shutting down the airport anyway then why could cops not just use a drone themselves to try to track down this one. The batteries are going to die eventually, just follow it home.

It certainly would in a court.However, I am fully aware of the fact that human memory is only marginally dependable, and that one individual is enough to easily sway and distort memories of an entire group. Countless media presentations of a drone should be more than enough to convince everybody who saw a distant bird that they were looking at a drone, so it only takes one or two false sightings to launch mass hysteria.Video related to memory manipulation:

People who are "persons of interest" but have not been formally charged should be similarly protected. And if some newspaper decides they will sell more papers by damaging the reputation of a private person then they can share their profits with the person who's reputation suffered. A substantial award for damages ought to do it.

There are some really big things out there.It could break the windshield, killing the pilot and crashing the plane.It could break the propeller on a small monoprop, forcing the landing (not immediately fatal, but still dangerous, depending on the phase of the flight).It could be sucked into the turbofan engine (airliners are capable of flying on a single engine, but having one explode on you is certainly an emergency).

content: Also - while less likely - you might have penetration of the aircraft skin that might cause damage to internal systems. Any damage to pressurised zones would not be a problem at altitudes where you're likely to encounter them - but would prevent a flight from cotinuing.Even less likely (but not impossible) would be foreign objects (drone bits) interfering with control surfaces.Then there's the possibility of instrumentation sensor damage - such as angle of attack sensors, pitot tube - and radio antennae. For that, it might be best to ask the NTSB - or a ground engineer - as to the sort of impact damage they already see from birds ... and tiny helium balloon transmitters that people launch.

Probably nicknamed so by some journalist who had watched too much Star Wars, but still seems somewhat fitting in that context.The conspiratorial part of me has begun suspecting that calling multicopters drones and getting the public worked up over them might be a way to take away attention and criticism away from military drones. (Of course, it's most likely just because of the usual click-bait journalism).Anyway, now they are writing about how Swedish police is buying new "anti-drone" equipment for millions because of this... someone is making a lot of money. Of course, not a word in the local news about the fact that there likely never was a drone at Gatwick.

It would be nice to have neighbors who mind their own business and who do not divulge information but that would mean people having a social level which is just impossible to achieve.But the media should be prevented from revealing private information about private people going about their private business and should pay damages to those private people who they expose without very good justification. If the media who published the information were to now pay a substantial sum to the exposed couple maybe the couple would feel somewhat remedied and maybe the media would think twice next time around.Quote from: Simon on December 26, 2018, 03:58:06 pmThe whole world is a mess.

content: Strange. some months ago I have read up some sources of drone hazard, also on airports, counter measures, even tests of radar back scatter of commercial drones.what I think: the gatwick airport team and the police has made the most damage in all. period. They have simply freaked out. okay, beside the regulations of operating a drone in UK (and EU) there are similar as described in Canada and US. (100m to important infrastructure, masses of people, private property etc., max 100m flight "level", in controlled zones max 50m, around airports 0m within 1,5km from airport. Drones below 250gr are free to fly (w/o license).The biggest commercial drones are like DJI Phantom: max 100km/h fast, max 2500m high, max 30min airtime, max 3500m (CE) radio range., 3kg weight, 0,7kg payload (Cam), 60cm square size, cost about $4000.Most quadcopter are way below this. In opposite some facts about bird strike tests: a "large bird ingestion test– at least one 3,65 kg bird body is fired with 360 km/h at a running engine".Okay birds are not made of metal, but breaking down the impact by size and weight, a avarage drone makes not as much damage as a 2kg bird.Drone sightings and even collisions where reported: even at Heathrow ( as I remember). There are rare, but there are already there.Okay, how to fetch such a drone? The israel press has at least 2016, 2017 and 2018 claimed(!) to shoot down a syrian drone in the northern golan heights with a Patriot missle (hehe: $2mio missle to combat $50 drone.)I have also found a report from june 2014 about such a waste of money.How to find? Radar back scatter of a large drone is around 0.05m at 24Ghz and 0.02m for a small drone (found in some test). this is the same size of a bird on a radar scope.Most (if not all) commercial drones are radio controlled by ISM 2.4Ghz or 5 GHz.there are many manufacturers with jamming eqipment with transmission power of 40W (400 times the power of the legal drone radio), some civil offered systems are able to jam from 200kHz to 8Ghz with spectrum analizer watched in realtime.Military systems have much more to offer.On the other side:even the russians got attacks by several self-made drones with explosives at the same time on more than one occasion in syria (Hmeimim and Tartus) this year.Okay: all these values say: Even If there was a drone, the shut down of the airport was way too much panic. This kind of reaction is something i would expect, if someone will bloat this thing up.Next: no Radar backups show some distinct drone / bird filght, no photos where made, no cctv cam footage (remember the ridiculous camera per resident ratio the britains have)... no one has seen the drone fly away, only disappearing...What if there is a small military drone hovering 24 hours and 2000 feet?

content: The piss off about this "incident" is that they will use it as an excuse to further restrict drones/model aircraft even more - even if there was not even any drone involved.This only hurts hobbyists who have common sense and won't hurt idiots who will fly drones in bad places anyway.One of the rules here in Canada is so vague that they are basically banned anywhere. Instead of telling people to look at ADS-B, and visually look for planes, etc and generally use common sense, they just make it so you can't fly anywhere that an aircraft can land or take off. Helicopters can land on pretty much any flat surface, so drones are not legal in those places. Water planes can land anywhere in a lake, so drones are illegal over any lake, etc... Instead of just telling people to use common sense and punishing those who don't they just have these ridiculous blanket rules.I'm thinking this whole thing was just a plot to demonize the drone/RC aircraft hobby. Yes, drones can cause a danger to planes, but go and punish idiots that are actually flying them near planes instead of making ridiculously restrictive rules that punish even people with common sense.Really I would not be against having a licensing scheme for model aircraft (drones etc...), different license grades would allow you to do more like the advanced tier could even allow long range flights and higher altitudes, but you would have certain requirements like an ADS-B transponder/TCAS, parachute etc.

Also when they say a "drone incident" a lot of them (like this one) arn't even drones, and some may be drones that are very far away. For example an aircraft flying at 37,000 feet spots the lights from a drone flying at 500 feet, that's considered a "drone incident". The drone may be flying illegally being that high but is nowhere near the aircraft.

Then a real drone, flew into the path of a departing A321, which had just lifted off, and it was ingested into one of the turbofans, causing catastrophic damage. The aircraft manages to do an emergency landing on one engine and no body was injured.What happens to the controller who made the decision to not to close the runway?Lets up the anti, and the plane for some reason did'nt make a safe landing and somone was hurt.As a passenger what would you like the controllers to do? Everything else in aviation is extremely risk adverse.

Each one can be a damaging projectile. The instantaneous forces imparted at impact will be a couple of orders of magnitude greater than anything a bird can offer.And this is based on stock standard consumer UAVs. Who's to say what a nut case might mount on one if their intent was malicious.While care should be taken so as to not overreact, being dismissive here is more dangerous, IMHO.

content: The largest and most significant mass in an impact is the battery pack, not the motors. At least for this type of UAV. A gas-powered fixed-wing RC model would produce the same reaction, probably at a lower cost and with longer flight time.No amount of laws or rules can prevent a deliberate act. So long as the UAV is pre-programmed (even holding a compass heading would be good enough for a single pass), launched from far enough away, and is considered disposable, tracking down those responsible is extremely difficult.

content: Quote from: Nusa on December 28, 2018, 01:13:11 amIt's not just the mass that needs to be considered - it's the rigidity of the structure. A battery pack may weigh more, but it will deform more readily than the rigid metal components of a motor. Deformation allows for the impact energy to be spread over a longer period, reducing the impulse force.That's not to say the battery pack isn't a risk - it most certainly is - but a motor would most likely be the first point of impact, causing penetrating damage. The battery pack would then follow, along with other motors, causing more carnage.The more I think about this, the more the actual permutations of what damage could be done to wings, control surfaces, engines, instrumentation, cockpit windows and anything else, means that I should not try to address these in detail. I'll leave that to the testing facilities and the NTSB (or equivalent in your country).

With the aviation industry being extremely risk averse, this is a major issue.With all the difficulties in devising, implementing and enforcing controls, there is an understandable feeling of pointlessness from some quarters - but if we don't takesomesteps, we will never find our way to a practical solution.Throwing our hands up and saying it's all too hard is not going to be any consolation if an aircraft is taken down by a quad copter.

Action can be taken depending on whether the suspected sighting can be verified or not.Shutting an airfield and causing chaos because "someone" saw "something" definitely seems like an overreaction.

content: I would argue that the greatest risk a drone poses is to helicopters as an impact on the rotor would almost 100% be fatal to all on-board the copter. A copter would be at risk if the rotor hit a large bird but a smaller bird should be survivable -- a drone, OTH, would be more likely to damage the rotor sufficiently that it would either break apart or become so unbalanced that the copter would shake itself to pieces. Additionally, copters are more likely to fly at lower altitude and therefore operate in the same airspace as drones.I own drones and frequent a forum like this but for the Phantom drone, and the thing that really gets me is that even on a board like that we get numb-nuts that think planes and helicopters are immune from drone strikes owing to a pressure wave in front that will push them away. You can ask them how planes hit birds and they have no comeback -- they are not thinking and instead convinced themselves they should be able to do whatever they want. These idiots will be the reason for prohibitive restrictions that we all know are coming.The Gatwick issue is hard to get a handle on as there were pictures and video of a drone that has been reported to be over Gatwick, but if the police and other authorities are now saying they're not sure if there were drones then who the hell was behind the pictures and videos we've already seen attributed to the "Gatwick Attack"!Brian

His only choice was to down power. Forutnatly the pilot on board, was excpetionally skilled and expereinced and was able to auto-rotate it down onto a golf course green and other than scaring a couple of golfers no other damage was experience suffered. What caused the vibration. The tape on the leading edge of one of the blades had come loose. it must have only been a few grams of tape. Imagine if things hadnt been so 'perfect'..

Generally they just chop even large birds (a wild goose could be 15 lbs) into pieces and that's it, although cleaning and inspection are called for later.Strikes aren't limited to rotors, of course. The most serious bird strikes on helicopters are when the bird smashes through the canopy, with results ranging from confusion to an injured or unconscious pilot. There's a reason you nearly always see helmets with eye protection on helicopter pilots.

content: Quote from: Mr. Scram on December 29, 2018, 08:07:09 pmThe risk to planes is there but not as high as it is for helicopters -- I made that clear in my first post. Helicopters are at greater risk because the propulsion and lift come from the same mechanism -- the rotor. Rotors are not weak things, mind you, as they need to support the weight of the copter and also tolerate expected impacts from hail, inspects, and small birds. They are not, however, designed to tolerate larger impacts and a large bird like a Canada Goose would pose a serious risk to downing the copter. If a copter loses power it can in many cases land by auto-rotating, but when you are missing one of the rotor blades there is no chance at all -- none! The damage to a rotor does not have to go so far as to shatter it, thought that would surely be the end, but even losing a piece of the tip or having significant deformation will so severely imbalance the rotor that flight is no longer possible. Planes are less at risk because the lift and propulsion are provided by two different things -- not so with a copter.Brian

And there I was thinking an Alouette was small, but it is massively bigger, and I know from experience that they survive much worse impact damage, and having impacts, including a couple of pilots who came back with bullets inside the engine, let alone lots of shredded tree. I can see that losing the blade tape on such a small frame would be major, but as the major function of the tape is to absorb impact from small debris and sand erosion larger more modern helicopters have a much better blade.From a structural point the main rotor is not the weakest point, it is very robust, and in general the front facing is incredibly energy absorbent material, with the tape there as a sacrificial material to prolong blade life. Changed blade tape on one 2 days in a row, it went out that night into a hailstorm at 300m AGL for a casevac, and stripped almost all of it off, but was otherwise fine mechanically, though there were a few more dings on the panels that needed some work.As to the blue and white, I used to trundle that Messerschmidt Bravo 109 out every morning to the flight line from it's parking lot, and leave the wheels back in the designated spot for them. Moving it was easy, clip on the wheels and grab the tail to lift it and push, and watch out for the rotors on the doors, and avoid the other helicopters in the area.

The DJI Phantom series of drones, by far the most common of the non toy drones, is about 1400g with the battery alone being about 470g. The DJI Inspire series of drones, a step up from the Phantom series and very popular with more serious drone users, is about 3.4kg before adding the gimbal and camera and more like 4kg with gimbal and camera.Brian

More serious drone users are going to follow the rules, because they don't want to get fined or have their kit destroyed in a collision. It's the kids dicking about with cheap drones who are the problem, not adults.India has gone one step further than geo-fencing,Drone owners in India must get government approval before every flight. Of course, that doesn't stop unauthorised use, just makes it harder for legitimate users.

Generally they are buying a drone in a lot of cases as their first R/C aircraft of any sort with ZERO background or clues as to what is or isn't the law let alone common sense entering their brains. As they have generally brought up the food chain of Drones a bit they are flying 800-1500g with ranges in the km ballpark.Kids with toys and short ranges of those pose little or no risk to any aviation. Generally sub 500g and a few hundred meters range at most.License, Registration whatever law you think may help still doesn't stop the determined or the terminally stupid.

That still happens to this day, most recently (that I know of) with F-16's, redesignated QF-16's. Prior to that we had F-4's converted to QF-4's, and F-106's converted to QF-106's. The Marines have automated some of their Hueys, allowing unmanned cargo runs.And, of course, there's the purpose-built drones that eliminate the cockpit entirely that we all know about.

December.First we heard of the drones was when we were about 20 minutes from landing in Gatwick. We circled around Chester for an hour, waiting for the airspace over LGW to open. It didn't open and when we were low on fuel we diverted to Glasgow.Here are the flight paths from flightaware:When we landed we cleared passport control and then went to baggage claim. Two counters were set up to deal with the 200 or so people on board. I didn't wait around. I figured it would take 90 minutes to get to the counter. Instead I took a taxi to the railway station and took a train to London.I heard that the people who stayed slept in a hotel. The next day they boarded a special flight to LGW. This flight got to LGW circled for an hour and then returned to Glasgow unable to land at LGW. The plane left sometime latter and landed at LGW. I don't know the times of these flights.I am out about 175 uk pounds ($225.00 USD) with little hope of recovering anything.When (or if) they catch DroneBoy or DroneGirl I hope they get severely inconvenienced, and that is the polite version.Regards,Jay_Diddy_B

You can put a ping pong ball right through a ping pong racket if it's shot at the right speed.That said I think it's best to deal with this on a case per case basis instead of having all the ridiculous rules that restrict the hobby, and all the fear mongering. This incident was nothing but a stunt to cause fear of the hobby of drones/UAVs. (UAVs is probably the proper term to use but I'll just stick with drone)One thing I do think they should do is make it so you have the option of setting up ADS-B on a drone, and registering it, and if you do that, you would have less restrictions, only requirements (such as avoiding aircraft, staying within so many meters of active aircraft etc). This could be fully automated in the drone's logic and allow for long range flights. Like how cool would that be if we were allowed to send a drone on a weather balloon and have it fly back down, and do other fun stuff like that. As long as you use common sense and do it safely I think stuff like that should be allowed. Only punish the ones that arn't careful, not everybody.

content: I have been reading some of the comments on this thread and a few people have spotted the flaws with the current situation in the UK and the likely direction these will go as a result of recent incidents.Firstly I actually use drones all of which are home builds using flight controllers based on open source software, so they can be easily modified to meet specific requirements, which means it is fair to say that most current countermeasure technology should be defeatable and that systems like geofencing are not implemented.Further to this in order to carry imaging payloads most of these are over 5Kg as they carry batteries providing between 5 and 20Ahr at 22V, as well as being made using materials such as Carbon Fibre and 6082 Aluminium in order to provide durability and stiffness to the airframe.This results in build cost that is below £1000, flight times of up to 40mins and a piece of hardware that could do some serious damage in an impact (although I would not condone such an irresponsible use of this type of equipment).The problem is that we started out with fairly restricted rules on drone use from around 7 years ago, I was actually looking at a project involving their use back then and had some quite involved discussions with the CAA, all of which lead to the project being dropped as we would have had to get approval on a per flight basis and this was just not feasible, Since then the regulations were relaxed considerably making drone use practical again, but now we are back to increasing restrictions on drone use which for users like me are just unworkable as it is totally impractical to register the drones I use as they are continually being modified.What would make more sense is to relax the regulations and push the education making it easier for those who want to use drones to do so responsibly, as the current track will just lead to an increase in unregulated drone use and as most of us are already aware if someone is going to pull a stunt like flying in restricted airspace or even worse, they are going to do it despite any rules that are put in place, just look at what happened in the UK by banning handguns that were legally held, it did not stop gun crime as those who are prepared to use hand guns do not care about the law, the same will happen with the use of drones.Unfortunately it is a small minority who spoil it for the rest of us.

content: So a few non fliers may be better informed about what geofencing is or isn't this is my backyard. Not shown on the CASA map is the local model aircraft field which has a permanent NOTAM on it and sits well within the 5km limit to the local airport and should really be shown on a Drone App as a warning at least.The Airport shown handles corporate jets and 20-30 seater turboprops and a fair bit of Helicopter traffic servicing offshore gas rigs. The CASA map is off their drone app and shows no go areas, warnings and advisories to users. It clearly identifies the emergency Helipad 500m from here but I am allowed to fly within those guidelines of 'get the hell out of the air if you hear or see a chopper'. The Airstrip located near the coast has the same level of restrictions and within 100m South of it I have done a heap of R/C Gliding on the sand dunes over the years.From the DJI 'Geo Fenced' map you can clearly show the lack of fence right up to the Airport boundary so ZERO meters even with it enabled. This is not the case with all Airports in Australia by any means but is shows the shortcomings of relying on it.The Geo fenced areas will no doubt be improved or change over time but clearly are not a fix or control mechanism.

The was in a remote area about 80km+ west of Salt Lake City and many km from anything approaching so much as a burg. I'd just taken off and was heading towards a nearby formation when I heard but did not see an aircraft. I quickly descended to about 10m and tried to locate where the sound was. After about 10 seconds I located it and sure enough it was heading right towards the formation I was heading towards. The small plane circled the formation and I was getting ready resume my flight when he continued around for a second loop. I dropped down still lower as by this time I couldn't count on him not heading closer to me and by my observation he'd descended to below 100m and maybe as low as 85m while cooking along at, about, 270kph give or take. As fast as he was going it had to be more of a sport plane. Anyway, you may see for yourself in this video -- action begins pretty near the beginning.Brian

I would certainly agree with that around airports, but in other parts of the world that's not a given.

content: Technically the Plane shown in Raptor1956's video should have been no lower than 500' AGL and the Drone should be no more than 400'. So there is a differential in the USA, Australia and most other countries that exists under the current rules. So the airspace is divided but not always adhered to. The act of dropping low is the best advice and action to avoid the possibility of a collision.This is a case where the full sized plane most likely launched at a different altitude and may or may not have known an actual height AGL. More common usage of GPS fed navigation aids are improving this sort of thing but traditionally you relied on charts and setting barometric instruments prior to launch. The Phantom by way of comparison when switched on would have set a zero point so referenced above ground level from takeoff time and place.So it is possible to innocently in the case of the light plane to be below 500' but they should err on the cautious side regardless of the remoteness. If they were at 100' (really obviously low) cutting laps numbers should be taken and photos lodged with the CAA in that case.

content: Quote from: Mr. Scram on January 01, 2019, 07:27:50 amBeen away for a few days...The rules in the USA (FAA) are that a pilot should not descend below 500 feet UNLESS it is a more remote location and away from people. That is, if you are in a remote location and there are no people or structures around then it is legal to descend below 500 feet. The location I was at is about 50miles from Salt Lake City and at least 15 miles from and significant settlement so on that basis it would be legal, however, there were people around the formation.The interesting thing as an aviation buff is that this small plane was really cooking along -- much faster than a typical Cessna 152/172. I could not accurately make out the make/model of the AC, but I'd surmise it was a low wing sport plane and by my eye he'd dropped below 300 feet and was cooking along about 180mph or so -- much too fast for a Cessna 152/172.I had another encounter with a fast moving low flying plane back in about 2006. I had hiked out to the Wahweap Hoodoos along the Wahweap River bed, which like most rivers in the desert are dry 360 days a year. The hoodoo formations are at the base of mesa about 150 feet tall that borders the dry river bead to the south and on the other side of the wash is another series of mesa's forming a valley about 1500 feet wide at this point. I heard a noise and when I looked I saw a large twin engine plane, perhaps 12-16 passenger, booking along the river at about the rim height and I'd guess moving at about 160mph or more. Thirty minutes later a helicopter came down and landed near me.GPS: 37.16218N, 111.7056WThe coordinates for the formation in the video are: 40.7091N, 112.6845WAs you can see both places are pretty remote...Brian

content: So it looks like they're using Rafael's Drone Dome system, radar and optical detection so that's going to be hard to avoid and jamming as a countermeasure. Makes a lot of sense, developed in Israel and tested by the army and probably RAF as well, it works, it does the job and high powered lasers are an add on option, maybe. It's a cat and mouse game and for now I think the cat is winning. Can smaller airports aford this system ?According to Jane's we had already procured this system in August 2018, delivery times might be a problemhttps://www.janes.com/article/82347/uk-signs-for-drone-dome-c-uas-system

content: Tonite @ 20:30.The Gatwick Drone AttackPanoramaWith the most detailed account so far of the three days of disruption and the first in-depth interview with Gatwick since the attack, Justin Rowlatt asks what really happened. Why has no-one been caught? Was there a drone at all? And what needs to be done to protect our skies?https://www.bbc.co.uk/programmes/m0003vwg
