Jet Strikes Drone Near Heathrow Airport (marketwatch.com)

smooth wombat writes: "A British Airways flight Sunday appears to have collided with a drone on a flight bound for London's busy Heathrow Airport in what may be the first such incident involving a major airline," according to MarketWatch. "The flight from Geneva, Switzerland to Heathrow, Europe's busiest hub, is believed to have struck a drone, the London Metropolitan Police said in a statement. The plane landed safely following the incident, which occurred around 12:50 p.m. local time. 'It was only a matter of time before we had a drone strike given the huge numbers being flown around by amateurs who don't understand the risks and the rules,' said BALPA flight safety specialist Steve Landells... 'Much more education of drone users and enforcement of the rules is needed to ensure our skies remain safe from this threat'."

      Yes. The battery is alot more dense than a bird. If a fan blade is even chipped, it can crack and splinter, in which case the entire engine breaks apart internally. There's a recent model simulating this floating around, and it shows the engine fan blades disintegrating in less than one revolution after impact.

      If a fan blade is even chipped

      Small chips are routinely repaired during engine overhauls by "blending"; filing and sanding away the sharp corners caused by FOD that accumulates in in-service engines. There are manufacturer guidelines covering the location and size of damage may be repaired through blending, and tool manufacturers sell specialized blending tools. Your claim that "even chipped" blades will disintegrate an engine is bogus. It is impossible to operate a gas turbine in real-world conditions without accumulating small "chips" in compressor and turbine blades and stators.

      Please don't make stuff up to amplify concerns about drones, or anything else for that matter.

    There has been no evidence presented that it hit a drone. Just speculation at this point

    Of course I get all my aerospace news from MarketWatch... However, other sources suggest the pilots saw it bounce off the nose:

    After landing, the pilot reported an object - believed to be a drone - had struck the front of the Airbus A320.

    As someone who works at a major Air Force bace that flies "heavies", I can tell you that often there is no physical damage and the only way to confirm a "bird strike" is the blood left behind, and small drones do not have blood.

If both those criteria had been met then your post might read a little differently. You appear not to notice the research that has been conducted on bird strikes on large jets for many years. You also seem to be unaware of the unlucky passengers of light aircraft who have had large birds land in their laps, along with chunks of perspex and aluminium.

    Civil aviation spends millions trying to avoid birds near the major airports.

    "perhaps it should actually show that small drones that weigh a few pounds really aren't more dangerous to aircraft than birds."

    Except that:
    1) We know (and act upon) birds *are* quite dangerous to aircraft.
    2) We know drones have a distintive characteristic that may make them more dangerous: they have an intelligent will backing them up (i.e.: adding explosives and/or the ability to crash on purpose).

  8. Re:Why no engine grill? by RogueyWon · · Score: 4, Informative

    You don't put a grill over the engine, because all that would do with a large birdstrike is add bits of metal into the mass of bird going into the engine.

    Airports can, and do, put a huge amount of effort into clearing birds from around their runways, due to the risks that birdstrike presents during takeoff and landing. To quote from one of Heathrow Airport's own documents:

    Birds can present a safety risk if they become caught in aircraft engines. Heathrowâ(TM)s bird hazard management team aim to make the airport as unappealing as possible for birds through habitat management, disturbing birds using distress noises, letting off flares and, as a last resort, through culling.

    Bird populations can even influence the siting of airports. When a major recent UK study ruled out the construction of a new airport in the Thames Estuary (to the east of the capital), the scale of the bird-management that would be necessary was one of several reasons cited:

    The operational risk to the airport posed by birdstrike could increase the scale of compensatory habitat required as it would require it to be sited further away, ideally to a minimum of 20km away from the site, and certainly outside of the 13km bird safeguarding circle, increasing the uncertainty as to its suitability as replacement for the habitat lost. It may also necessitate additional mitigation measures to be put in place. If any remaining bird habitats within the 13km safeguarding circle (that is those not already displaced by the airport's direct impact) were considered to pose an operational safety risk additional mitigation measures would be needed and it may ultimately be necessary to remove those habitats, increasing further the environmental impact and cost of compensation.

    The CE logo is protected, and there are fines for using it withoutwithout certification. So instead they use one that is very similar: In the proper one the circle described by the C intersects the one described by the E such that the outlines (if they were present) would overlap exactly.

    Anything that has the other logo is colloquially known as Chinese Export.

    What's really dumb is the general public is largely ignorant about the difference. If your house burns down due to a faulty CE certified device you can have redress. If your house burns down due to a faulty Chinese Export, well it was uncertified so tough shit.

    Wow you would think the PHD level engineers that have been designing jet engines for decades would have thought of that ... and maybe if it was so easy, they would have done it by now ?

    There's only about a billion reasons it wouldn't work, and one of the first that springs to mind is that jet engines are sucking in air - at a huge speed (in many cases several times the speed of sound)... you stick a grill in there, you are reducing the possible airflow. That grill will have to be made of something incredibly (probably impossible) strong just to prevent it getting sucked in itself (seriously - you have no idea the force a jet engine generates -it's not like an air-conditioner - those things put out hundreds of KILONewtons in thrust). And if you actually build your super-grill, you will hugely weaken the engine because it will not be able to get air in as fast. Even most basic grill that actually does something useful will be at least a 30% reduction in engine power (50% is more likely for anything strong enough to do the job)... so now you'll need twice as many engines. Which means twice the fuel, and of course you've greatly increased the weight of the aircraft so you have to increase the wing-size massively to compensate... but that means you have to go *faster* to be able to generate enough lift which means you need more engines...

    They don't call it the tyranny of the rocket equation for nothing.

    Oh, yes, definitely, the manual for the Chinese drone should include all the relevant air safety laws for your location. Just like my Japanese Supra came with a copy of the California Driver Handbook. Oh, wait, it did not!

    Knowing the applicable laws is the user's responsibility. The drone's documentation should contain what's applicable to the drone, not a compendium of all laws governing the use of airspace from the North to the South pole. Even if the local regulations required that the relevant laws are included with the drone, it would be probably left to the local distributor to do so.

    Just like other conspiracy cults before them, say flat earthers, anit-vaxxers, birthers, 9/11 conspiracy nutjobs, and UFO creeps, Slashdot is now home to the DDD: Drone Danger Denial cult.

    1) The first rule of DDD: drones cannot cause any problem ever in any situation.

    2) The second rule of DDD: always defend drones as harmless no matter what the circumstance. For example if firefighters call off aerial retardant drops because drones are flying in the fire zone: the missed drops didn't make any difference and/or drones didn't pose any interference and the authorities should have just kept flying.

    In the current post three of the major denial themes are stated.

    1) It wasn't a drone.

    2) If there was a drone, nothing happened.

    3) If there was a drone interaction, there was no actual damage.

    It's so simple even the dullest of Slashdot Pundits can execute it with ease.

    BTW, I've actually participated in a project with the FAA addressing bird strike mitigation. They take any physical impact on a aircraft very seriously. It's not just birds, but any strike by FOD (Foreign Object Debris). That includes anything on a runway, like trash. At DFW airport in Texas, they have a problem with foxes who live in the airport and are stuck by aircraft. They collect and monitor the corpses, and have a burial location for their bodies. The FAA has records of rodent strikes, when their carcasses are found on runways. Anything hitting a aircraft is considered very significant. Saying that it's not important is just a pledge of allegiance to the DDD. A true blue cult member.
