Heathrow Plane In Near Miss With Drone
An anonymous reader writes with news about a near miss between a drone and a plane near Heathrow. "An unidentified drone came close to hitting a plane as it landed at Heathrow, the Civil Aviation Authority (CAA) has confirmed. An Airbus A320 pilot reported seeing a helicopter-style drone as the jet was 700 feet off the ground on its approach to the runway at 1416 GMT on 22 July. The CAA has not identified the airline or how close the drone came to the plane, which can carry 180 people. It gave the incident an 'A' rating, meaning a 'serious risk of collision'. This is the highest incident rating the CAA can give. Investigators were unable to identify the drone, which did not appear on air traffic control radar and disappeared after the encounter."
until these morons flying drones over and around airfields cause death, probably some kind of small light training vehicle with an inexperience "pilot".
So, being that it is called "An unidentified drone", do we know that it was a drone and not a bird or something else?
How about we just call it for an Unidentified Flying Object until we figured out what it was?
When two planes almost collide, they call it a near miss. It's a near hit. A collision is a near miss.

UAVs (sometimes called "drones") shouldn't be operating around airports but the likelihood of one downing a transport category aircraft is just about zero.
Thank goodness my Amazon drone-delivered goods were not destroyed by this incident.
If Pandora's box is destined to be opened, *I* want to be the one to open it.
Drones are mostly made out of solid plastic, except for the battery and the motors. I'm not saying the turbine fans would be perfect after swallowing one but I'm pretty sure it would be no worse than a bird-strike.
Seven puppies were harmed during the making of this post.
Of course, a thing made mostly out of solid metal is much more dangerous than a bird.
Bullets are made of solid metal. Most hobbyist R/C aircraft, that are considered drones, are mostly Styrofoam and/or plastic. The hand built ones are usually balsa wood wrapped in shrink wrap plastic film. There are a few larger hand built R/C plane s with metal skin. But I don't think I've ever heard of hobbyists at that level being so irresponsible. It's become more of a problem since the relatively cheap "ready to fly" planes have gained popularity.
It would seem that a drone is the perfect terrorist weapon to hit a starting airliner with.

Geese have managed to bring down jet fighters so a bird strike is bad enough.
Unless said drone carries some hardened steel components, this is more like a collision with a bird. Even airplane engines (the most vulnerable part) are designed to withstand that. A direct collision will probably result in some light paint scratches on the airplane. Unlike the case of an airplane collision, the destruction of the drone is not an issue here.
What is going on here is that some bureaucrats inflate the risk perception of something that is basically a non-issue to look really, really dangerous. This is likely done for purely political reasons, to inflate their perceived importance.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
Yes, it IS a threat. And a responsible person wouldn't be flying these things where they can put other people's lives at risk.
Yet airports DO take measures to discourage birds from being in their vicinity. Now, most birds generally don't fear fines and prison sentences, so the measures usually take the form of: (i) changing the environment, to make it less appealing -- removing surrounding trees, food sources, etc; (ii) trained birds of prey; (iii) sound-generating devices.
RC aircraft have historically been used by a small number of (responsible) hobbyists. Drones are becoming more widespread, and their owners are starting to include idiots.
It's a shame that some idiots are behaving this way. I say release the falcons on them!
And you think anybody would be flying a commercial quad-copter near a runway approach? That is BS. Nobody is going to risk not only a very expensive piece of equipment but also a huge fine and possible loss of permission to operate drones. This clearly was something far lighter and far less expensive.
Also, Li-Ion can _not_ explode. It burns, very hotly, but it burns _slow_. There is no "could" here. Really, there is not. Goose feathers are a far better explosive than Li-Ion batteries. They _can_ explode if pulverized finely enough and mixed just right. Does that happen? No. It does not. Would it be a problem? No. Not enough energy in there to do actual damage. If you want a drone to blow up an airplane engine, you better add some pretty damn powerful explosive.

Let's trust Wikipedia on bird strikes and assume that small objects (under about 10kg) rarely cause a catastrophic collision, mostly it looks like bird strikes and similar are survivable for planes, they just cost lots of money. Looks like most aircraft aren't going to fall out of the sky even faced with a drone operator who successfully crashes into a plane. However the photos show it can make a pretty mess of expensive jet engines.
So I suspect that commercial interest might also be at play, it would be in the airlines' interest to claim a terrorism threat to stop idiots going to the supermarket in the morning then flying a drone near commercial airspace in the afternoon. Going to cost a lot to replace one of those jet engines from the look of the wikipedia photos showing what happens when a bird hits them.
Seems like if you want to commit an act of terror then a 5kg lump of plastic isn't likely to knock an airliner out of the sky, but it will probably cost the airlines a lot of money so I can imagine they'd quite like some regulations in place to stop idiots flying them near their planes.
I'm fed up with hearing the old trope that engines are tested by firing geese into them. Whilst this is true, the test is to ensure that the engine does not completely disintegrate peppering the cabin with shrapnel. The engine is most certainly not unscathed and if not written off completely would require extensive and costly refurbishment.
A drone may not be as heavy as a goose but it would very likely cause damage to the turbine blades resulting in reduced power and vibration and necessitating expensive repairs. Reduced power would also pose a danger.
Consequently, it goes without saying that airports do everything possible to prevent bird strikes and will presumably do the same for drones.
It's unfortunate that idiots like this (and the idiots that shine lasers into cockpits) will spoil it for us all. Inevitably, good toys will eventually be banned.
A pilot earning a small fortune, whose entire professional life is based on trust in him to save lives, whose entire career can be blighted by a single "what I saw wasn't there" incident, who's sitting next to co-pilots, lying in order to get an aircraft that he probably plays with at home himself banned?
Yeah. Right. It's all a conspiracy. Or some dickhead tested out his kids Christmas present and didn't know the laws surrounding drones because "it's just a toy", or wanted to get a cool shot of a plane taking off.
Heathrow is restricted airspace. NOTHING should be in that area, it's the world's busiest airport. You report ANYTHING out of the ordinary as a matter of course, as a pilot. And radar won't see a drone any more than it will see a house, or a car, or a cloud, or a big bird on it's own, or a lost birthday balloon. It's looking for aircraft. And all aircraft carry transponders blurting out their name and position by law anyway, which is the basis for air traffic control. Radar isn't there to find these kinds of things.
Occam's Razor. Either it's a conspiracy by the airports, the pilots, the governments and the CAA to ban drones that they themselves are using. Or it's some idiot with a Christmas toy. And they are already having enough problems with laser pointers, etc. by such idiots. I'm going with the later.
I would rather trust the CAA's own reporting and videos on Youtube ( https://www.youtube.com/watch?... ) showing bird strikes and what one (that's 1!) goose can do to a £230,000 engine. Three strikes a year which result in emergency landings, and that's just in UK airspace. Sometimes strikes aren't through engines, but through cockpit windows.
That is a risk.
Drones? That's just fucking lunacy. I'd go so far as to call it malicious intent.

Around an airport controlled airspace is shaped like an inverted wedding cake. The smallest layer - which contains the runways - touches the ground; therefore you can be knee height in there and still flying illegally if you don't have permission.
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
A drone is likely to have screws and other hardware that are hard steel as well as a high density power source (battery).
The high speed interaction between a airplane with a thin aluminum airfoil and jet turbines and a steel hardware is not part of the certification tests, so it is just a guess what would happen.
If it hits the aircraft skin, it might just dent or might punch through.
But if the drone was ingested into the engine, the steel parts might be spun around by the turbines and eject at very high speed out the side. The shrapnel would be like bullets. It would be a roll of the dice if they ejected into a fuel tank, flight control system, or into the passenger compartment.
So, no, this is not just some political game. Drones need to be separated from other aircraft.
There are rules to keep aircraft separated from each other and drones need to respect and follow those rules just like any other aircraft. That is why airspace near a airport is "controlled"
