Re: Drones
You're correct, the drones that you can buy on a shelf most likely won't bring down an aircraft. Large industrial drones, like the one reported, are capable of going through flight deck windows of airliners.BennyD wrote:Most common drones would not be able to bring down an airliner.

Well in an ideal world they wouldn't, which is why airfields employ wildlife control units to minimise the risk. I stress the word minimise though, because you obviously can't remove this risk completely.Spijed wrote:How do planes currently cope when they come near seagulls, or geese for example?

Re: Drones
No question they should be banned. Anyone caught with one and in particular causing a problem like this should have a very severe sentence imposed on them. But that won't happen will it? Our authorities are clueless and useless. The police are more interested in hate crimes and speed cameras (cash cows) than solving dangerous crimes, we have a PM who couldn't negotiate her way out of a paper bag. We have an environmental secretary telling us to take bottles etc back to the shops for a rebate, thereby likely increasing shopping traffic and polution. We have a communist leading the labour party. We have Blair, Major, Campbell and Clegg roaming the corridors of the EU in Brussels advising them how to thwart a democratic vote in THEIR own country. It goes on. The establishment is pathetic.

A little off topic, but when do you think drones will take over from manned fighter aircraft? I would imagine we can already create a drone that could perform in ways in which a pilot would not be able to stay conscious.

I would have thought a drone ending up in one of a twin engine aircraft's engines whilst taking off would be very dangerous.
I'm interested to know how the drones were detected. Radar I assume.

Re: Drones
At the risk of further ridicule from Billy Balfour, performance A aircraft (large commercial airliners) have to be able to lose an engine at maximum take off weight, and at rotate speed (VR) climb away safely. They can then climb and maintain a level above safety altitude, make a single engine approach and either go-around or land. Pilots have to demonstrate their ability to carry out this manoeuvre in every simulator they do. Consequently, it’s not a dangerous event as it is well practised.Hipper wrote:I would have thought a drone ending up in one of a twin engine aircraft's engines whilst taking off would be very dangerous.

Re: Drones
I don't get why they can't find them. In World War 2, resistance radio operators had to keep their signalling short because they would be caught by German tracking devices. Why can't they find where the signal is coming from?
Or a bit more low tech, they say that the thing has landed for new batteries several times. Can't they follow it?
I bet if someone in Afghanistan was flying a drone near a military base, they would have the equipment to track it.
And I hope that when they do find the culprit, they give him a bill to pay for all the expenses. Hopefully he's got a nice house that can be repossessed.

Re: Drones
I’ll bow you your experience in such matters. However, the CAA and airport authorities will always play it very safe because any damage caused by such air proxs will be the subject to mass litigation, and they are not willing to be exposed to such financial risk. Nobody said the volcano episode was a huge over reaction at the time but it was and we pilots knew it. Btw, If there are no drones over the airfield at the moment, why is it still closed? It shouldn’t be. How long after the drone disappears is it safe to fly? Almost immediately. The fact that the airfield was closed until early this evening despite no further sightings points to a huge overreaction. 760 flights disrupted by a couple of drone sightings is, IMO, completely unnecessary.Billy Balfour wrote:Is that so, Benny.

Re: Drones
I just think they are playing it safe Lancaster. Nobody can be sure of the intentions of the operator so it is the safest thing to do for the time being. However, it can't remain closed forever so at somepoint they will have to decide to reopen and just hope it doesn't return.Lancasterclaret wrote:I wonder if there is more to this.

Bit fishy that just after the government steps up its plans for leaving the EU with no deal (something that could severely disrupt air travel) this happens at Gatwick.
Is this a dummy run to see how we cope with major flight disruption? Is this all part of a test?

It's only taken the government (The defence secretary) almost a full day to bring in the military and their expertise and technology.
Makes you wonder what the government are actually for, and why we bother having armed forces if we don't bring them in to deal rapidly with this sort of incident.
Really feel for all those people and businesses being disrupted by this, and if the govt can't demonstrate that they can deal rapidly and effectively with this, then it will likely become a regular occurrence.
