London's Heathrow Airport Halts Departures Over Drone Sighting (cnbc.com)

London's Heathrow Airport halted departures on Tuesday after a report of a drone sighting, less than a month after a similar event crippled operations at a major U.K. airport. From a report: "We are currently responding to a drone sighting at Heathrow and are working closely with the Met Police to prevent any threat to operational safety," a spokesperson for the airport said. "As a precautionary measure, we have stopped departures while we investigate. We apologise to passengers for any inconvenience this may cause."

The skin thickness of an A340 at the leading edge slats is 1mm (2mm for an A320)**. 0.04" is 1.0.16mm, so the thickness is about right (the video shows the impact where the thickness to chord ratio is fairly high, which suggests near the root).

      Leading edge curvature may also effect the results. A relatively thin wing will have a higher curvature which tends to be stronger than a thicker wing.

      Another factor is the damage caused to the systems. The damage caused to the M20 will cause airflow to separate early, so the area behind the impact is unlikely to generate much lift. That's obviously bad. For a commercial aircraft, you're also damaging the slats which are generating a significant amount of extra lift (assuming the impact is at low level), as well as reducing the lift along the wing. Of course, the larger the wing, the smaller the percentage of lift lost due to damage will be.

Even if it could, it's so docile that it would be hard to hit moving aircraft. Steering into an engine of a moving passenger jet would be quite a challenge. Even a stationary plane's engine would be difficult to hit because the Air has sensors that won't let it crash into anything unless you ascend into it from below or fly into it side-ways, in which case you can't see where you are headed.

    My racing/acro drones would be better for causing mischief, but not much. They do as I tell them, and are both tough and nimble, but it was a major effort to develop the skill to fly without fear of accidentally crashing. I've spent a lot of time practising on a simulator and flying through hula-hoop sized gates in wide open spaces, but still have trouble finishing a lap around a 10-gate track without crashing, even when that is my sole aim (ie.

      The chances of a drone getting into a jet engine are extremely low, but they will make a serious mess if it happens.

      When a small bird like a pigeon strikes a modern turbofan engine the main fan converts it to coarse pate and hurls most of it through the bypass channel. Any small amounts that do pass through the core of the engine are unlikely to damage the turbine wheels. Ingesting a larger bird like a goose usually causes main rotor failure which will destroy the engine immediately.

      The important difference with a drone is the motors. They are dense and extremely hard (compared to a pigeon), so when they impact the main fan they will cause significant damage. This could range from a vibration shutdown to a 'blade out' failure. In addition any metal fragments which enter the core are likely to cause a turbine wheel failure in which case the engine is usually scrap.

      Training does cover the possibility of engine out during takeoff because bird strikes happen at the worst possible time (low speed, low altitude). But it's not something you want to do unnecessarily, and writing off multi-million dollar engines ( $25M for an A380 engine) is not good for business..

    NOBODY in the media has picked up on this. Actually thought for a minute about how ridiculous the assertion is.

    Sure, a 500kg military drone might do some damage if well aimed. But nobody is talking about one of those. There was an experiment in which somebody fired a fairly large drone out of a cannon at a very light aircraft wing and did major damage (but still did not destroy it), hardly relevant.

    Where is the risk assessment? There is about 0.6 fatal accidents for every million airline flights. So a 1 in 100 million additional risk is something to be avoided, but you do not close an airport because of it.

      A 500g drone with a steel pipe and steel cable attached? Good luck getting it to fly at all.

      Presuming you step up to a big enough drone to get your chosen payload off of the ground, the force will definitely have to be with you to fly it into a jetliner's engine.

      Assuming you really are a Jedi, the result will be an expensive ruined engine and the plane making an emergency landing on it's remaining engine.

      So we have no evidence that there was even an actual drone at Gatwick or Heathrow at all, and now you're suggesting that someone might make an intentionally malicious drone?

    Because it's cheap, allows more complex flight paths and the ability to accurately position hold.

    Once you are in the air it is very difficult to measure how far you have traveled without GPS. Dead reckoning is fine if you want to just fly-by, but to know you are at a particular location you need gps.

    As it happens, I do know Heathrow very well. I live nearby and have used it many times. It's in an area of relatively high population density (apart from the reservoirs and lakes a few miles to the west).

    The airport is bounded on two sides by major motorways with another major road to the east and it has terminal buildings in the middle. Aircraft are parked between the runways and along the side of the airport.

    It would be difficult to draw a shot line that didn't run any danger of collateral damage.

    Even a lower powered cartridge (which would mean dashing around on the ground to get closer to the drone, with all of the implications on safe movement airside of aircraft and vehicles) would pose a problem with debris.

    If we took it to extremes and assumed that your shot was practically out of energy at the airport fence, a slow moving bullet hitting a car going at 70mph would still cause damage and may shock/distract a driver into swerving into other lanes [people in the UK not being accustomed to gun violence].

    You may know Heathrow, but you don't know a thing about firearms, and not much about aircraft operations. Firearms: Why use a rifle/pistol? A shotgun has a maximum range of about 300 yards. It was *designed* to hit flying targets. In terms of the risks of collateral damage, how about looking at the number of casualties on the ground from the Battle of Britain? Ya know, the one where there was massive air combat over a large urban area (London). Aircraft: so, you have to clean up the debris. You have to do that on a regular basis, due to ground accidents (you didn't think that there would be no collisions between all those trucks that run around the field, did you?), animals (it's a *grassy field*), and wind blown debris. What you're looking for is a zero-risk, zero side effect solution. 'Taint no such thing.

    Yeah, if somebody with advanced technical skills is doing it, it might actually make them easier to catch.

    It is a really stupid type of thing to do, it is on the level of a prank, but a prank that can send you to prison as a terrorist. Any smart person who is insane enough to do that already is on the list of people who make online threats. They probably got onto the list with stupid jokes that they didn't realize would be taken as threats!

    And did they do it without having to do an internet search on it first? Only if they're an engineer. If an engineer decides to become a terrorist and this is what they went for, they'll probably be pretty easy to round up. And also, "Oh, good, they didn't hurt anybody."

    The total radio connection time is arming the flight controller at launch and then radio control to land.

    OK, but you've already done this in public. The military monitors radio traffic. Operational information about your control system is already stored in databases, but it isn't parsed out or cross-referenced or anything. Yet.

    If you turn into a terrorist trying to disrupt air traffic, you'll be even easier to catch that the guy using an off-the-shelf system.

    Being more clever doesn't actually help the terrorist in this case; it simply shows a lot more planning and increases the prison sentence they'll get. It also helps them to stand out from all the morons who are obviously not clever enough to have done it.

    GPS is receive-only, you don't transmit anything, so that much is reasonable.

    Dead reckoning takes a long time to program, and has to be tuned for each device. GPS you only have to do standard GIS transformations, and the rest of the hardware is irrelevant.

    Dead reckoning you give up the first time you try to operate it outdoors in a slight wind.
