Height of stupidity: Heathrow airliner buzzed by drone at 7,000ft

Re: I call bullshit

They CAN be a metre long, but the craft spotted in the first tale WAS NOT A FUCKING DRONE! It was remotely piloted using FPV goggles as hinted at in the article. That makes it not a drone as it was in no way, shape or form operating autonomous. I can even believe this as FPV flyers have been known to cover quite large distances and reach pretty large altitudes.

The second story I find utter bullshit. Because either it was a twin PROPELLER/ENGINE fixed wing craft or it was not a remotely piloted craft. A twin 'copter' craft of the size described simply doesn't have the battery power to get up to 2,300 meters. A twin engine model aircraft MIGHT be able to manage it, but then it should not be described as a drone by even the most braindead of investigator, reporter or pilot.

Re: How about enforcing transponder codes for drones?

There are no mode-s transponders of a size suitable for mounting on large size model aircraft, let alone anything smaller. Even the ones designed for gliders are barely up for the job, are quite hefty and suck a lot of battery power.

Re: Someone explain please:

accuracy mostly. The measuring error multiplies with the measurement. So multiplying nano amps to get amps means you also multiply the measurement error by 1E9, so a 0,001% measurement error becomes a 1.000.000% measurement error. Not exactly accurate in other words. Measuring a milliamp means a 0,001% measuring error becomes a 1% error, which is much more acceptable.

Re: Down for the count

The problem with a theoretical standard is that it's very hard to calibrate something very very accurately against a theory. Having a physical standard allows for much more accurate calibration of powermeters and sources across the globe. With a theoretical standard there is no way to prove that a 1.0000105 amp current measured in Japan is the same as a 1.0000105 amp current measured in Canada, unless you bring both sources to the same location and measure them with the same meter in the same circumstances. (And then when you install everything again in the lab back home you are AGAIN not sure if the standards are the same). With a physical standard like proposed here its actually possible to prove that the two measurements are indeed the same.

Re: Humans still have their uses

This is exactly the reason many low end jobs won't be automated any time soon. Especially the tasks where flexibility of process is required automating things is very very hard. Automating a stacking system seems simple enough, but is actually a massive challenge. Automating stacking of different kinds of boxes with different weights is even more of a challenge. One that meatbags (even on the less educated end of the scale) deal with quite easily but can be a nightmare to automate and keep running.

Automating requires a Return on Investment that outweights the initial investment costs within a reasonable time. If automating a task doesn't return the initial investment in the economic lifetime of the system (Typically between 5 and 10 years) then it's simply not automated.

Re: Plane vs Cars

I think you underestimate just how many fields of engineering NASA has experience in. The explanation from their experts has probably been dumbed down a lot (either by themselves due to the audience they had or by the reporter) but is largely correct. If in a flying incident, most of the time if you have only 1 second to react, you are dead. Inertia and aerodynamics mean there is just no way to change direction fast. On the road a second can be enough to change direction enough to avoid an incident. On top of that minimum separation in the air is usually several miles, several hundred meters at minimum for GA traffic. Land vehicles tend to operate within linguini to brontosaurus lengths from each other, making available reaction time that much shorter and collisions that much more likely.

Re: Mozilla doesn't need a new logo

What AMBxx said. Mozillas main product (firefox) seems stuck, going nowhere fast. Bloating from the fast and responsive browser it once was to something as slow and cumbersome as many of the browsers it is trying to compete with. Mozilla seems to be lacking direction (the big danger for open source volunteer organisations it seems) and this is going to break them up if they don't manage to keep enough differentiation to keep their users.

The calm before the storm: AMD's Zen bears down on Intel CPUs

Re: The problem for AMD

@P0l0nium

Intel spends those billions on R&D alone. There really is a massive scale difference there. Getting a fab process "for free" still doesn't give them the sort of deep know how about nano-lithography Intel gets from doing all the research itself. Once things are worked out the slightly less clever can get/keep it working. But when things inevitably go south because of some unforseen variable you want the really brainy chaps around who have the "fingerspitzengefühl" to get it fixed. From what I'm seeing Global Foundries is still playing catchup (Though they are making good progression and are certainly gaining on Intel)

The problem for AMD

AMD has to rely on external fabs for their semi-con production expertise, while Intel does everything in-house. Because Global Foundries just doesn't have the same sort of cash to burn as Intel they seem to be a step behind in terms of production expertise and capabilities. This hampers AMD as well. It's all well and good they can deliver a chip that can compete with Intels CURRENT offering, but what about the next generation?

Re: This makes me wonder . .

THERE IS NO POINT IN POSTING A REBUTTAL! I have plenty but I refuse to waste my time on someone who refuses to even THINK for a second! You REALLY can't understand why we say the foundation is moving (relative to a fixed reference frame located around the earths center) at 1040 km/h? You REALLY can't understand why the top of your hypothetical ladder HAS to be moving relative to that same reference frame FASTER than the foundation? You REALLY insist on rotating the entire reference frame along with the ladder around the reference frame? Because we can STILL make the same calculations, showing the same damn thing, it's just going to involve a lot of very complicated mathematics that is frankly entirely pointless because the same sums in a fixed reference frame barely cover an A5 sheet of paper.

Re: 90,000 feet

And this is not - it contradicts the earlier statement.

Even if you're in a thermal, both aircraft have a responsibility to avoid conflict. If that means you have to leave the thermal because you've seen the other pilot and he hasn't seen you - that's how aviation law works. You do not have a god-given right to stay in the thermal while everyone else gets out of your way, even if power pilots will try to afford you that luxury.

I did not intend to make it sound like I assume its a god given right. And when in a position to do so I (and most glider pilots) will always do my best to avoid other traffic. Something to keep in mind however is that head on traffic on a colission course is REALLY hard to spot. Circling gliders present a changing profile alternating sunlit and shadowed making them slightly easier to spot. When in a thermal with more than one glider just exiting whenever you want may not be an option. Thus while a glider pilot has an obligation to keep a lookout and get out of the way if he has to most glider pilots will prefer to stay in the gaggle or thermal because it makes them easier to spot. If a motor plane flies through a gaggle of 7 planes he has either plain not looked out or has decided to just fly through it anyway. Which makes him an asshat. The gliders will get out the way, but we won't be happy about it. (Pilot was tracked down and received a VERY stern talking to from police in this case. He was visibly shaken when he saw a cockpit video from one of the gliders showing just how close it came to a midair. He had the sun in his back and was at the same altitude all the way in. There was no way we could see him. He and his copilot admitted to be studying a map because they were lost. It's loss of awareness incidents like this that give glider pilots their hatred for Fuel to Noise converter cowboys.) Like I said in my last post, lets learn from one another. Because there are plenty of glider pilots who don't understand why its a bad idea to be following a cloudstreet right at cloudbase at 200 km/h. And plenty of motor pilots who don't understanding why it might be better for them not to do the same

Re: This makes me wonder . .

The point we are all trying to make is that the ladder is NOT just increasing altitude it is increasing the velocity of the second bowling ball to match that of the first. The end result of your thought experiment is indeed 2 bowling balls in the same energy state (i.e orbit). You are confused as to the process to GET there. Lets take a closer look at the space elevator example you give. Indeed both ends are at the same angular velocity relative to the earths Center of Gravity. They are however not at the same velocity along the orbital path. To understand why lets look at another object, the rotor blades on a helicopter. The blades are perfectly straight and (apart from a lag hinge on some helicopters for the pedants out there) remain perfectly straight when spinning around the shaft. The blades attach to the hub with a short stub some distance R from the main shaft before the airfoil profile starts. Lets call this the root of the blade. The blade has a length L to the tip of the blade. As the rotor blade spins the root describes a circle with radius R. And a circumference of 2*Pi*R. The tip makes a circle with a radius of R+L and a length of 2*Pi*(R+L). Because the tip covers the same full revolution as the root to keep the blade at the same angular velocity and the blade straight that means each revolution the tip of the blade covers 2*Pi*L more distance relative to the root. Because the tip makes the revolution in the same time as the root is means it covers more distance in the same time and thus HAS to move faster. Now lets imagine R is equal to the earths radius and L is equal to GEO altitude. Now we are looking at the idealalised version of a space elevator. The same basic equations still apply and so the space end of the space elevator has to have a higher orbital velocity relative to the earths CoG than the earth attached end.

Re: 90,000 feet

Btw druck, as with cyclists its the few rotten apples in the bunch that cause the bad name. Worldwide gliders make up the majority of air traffic on a good day yet they tend to be involved in proximity or airspace infringement accidents LESS than powered GA. (Atleast according to the accident databases I have access to)

The same goed for GA pilots. Many are well behaved and "we" stay out of each others way. But there are some that just don't want to understand why glider pilots fly the way they do and that feel gliders don't have a place in 'their' skies.

I apologize for the somewhat harsh tone of my last post. It fits the definition of shouty glider pilot idiot perfectly. Unfortunately I had to deal with one of the idiot versions of a GA pilot that day who did his very best to kill me. I fear I stooped to his level a bit. Guess I lived up to my username.

As for the GA pilots hating on glider pilots, I encourage you to take some gliding lessons. I think it would help in the mutual understanding and it might help your flying skills too. Not having an engine really changes the way one thinks about altitude, speed and position in the sky. Might come in handy one day in an engine out scenario (but lets hope it doesn't)

May your skies be just the right amount of cloudy.

Re: 90,000 feet

Typical power pilot attitude. Airspace and traffic awareness is typically much higher with glider pilots than it is with powered planes. I cant even count the number of times I've seen a powered plane fly through a gaggle of gliders circling in a thermal on my fingers. Most often without ANY indication they even noticed any other traffic.

As for the complaints about color, most gliders nowadays have high-vis anti colission markings. A luxury I have yet to see on the many equally white composite powered planes that litter the skies on a good day. And keep in mind, if its VFR airspace, ALL planes have a responsibility to maintain lookoit and traffic separation. And whether you like it or not, if I'm circling in a thermal I actually have a right to keep circling and YOU are obligated to avoid me. If I'm right next to an airfield I might listen in on the radio, but I am under no obligation to report my position and many airports actually prefer gliders to NOT do so as long as they stay out of the airspace.

Same when landing, a motor plane has the luxury of a go-around. I get ONE try, and it'll end on the ground one way or another. And even though on many field the motor and glider circuits are separated and I will do my very best to avoid getting in the way I have had to avoid asshat motor flyers buzzing the circuit more than once.

As for transponders and contacting ATC, in many places small GA and glider contacts actually get filteres from the returns to declutter the screen. There is a good chance ATC cant even see me when I DO carry a transponder. Which makes keeping a visual lookout all the more important.

On top of that there are many vintage gliders still kept airworthy. Do you really expect someone to install a 2000 euro transponder into a plane that probably never ventures far from home and is worth probably about the same?
