    If it turns out to be the case that EMI or RFI caused a 200-tonne modern civil airliner to crash, can anyone how much sh!t the industry would be in? It would be catastrophic. When it dawns on the world that radio transmissions or electromatic fields could bring down an airliner…..

    It’s nothing new. The military has successfully used electromagnetic fields in combat, so what makes you think that airliners are immune to it?

    Jammers can confuse electronics sometimes even cause failures. EMP weapons are designed to cause failures. There are even some suggestions that some military radars are being used as jammers and possibly to cause failures. Some of the new radars have some very remarkable abilities to focus their energy.

    As for a phone shutting the engines down, if EMI or RFI can cause such a thing I’d expect it to be much more likely to occur when the aircraft flies within the vacinity of something like London’s Crystal Palace TV transmitter (1,000,000 watts output) or West Yorkshire’s Emley Moor TV transmitter (870,000 watts output).

    As I said I am highly skeptical, but I think it’s worth some investigation, particularly if evidence ends up pointing in that direction or if there is no clear cause.

    Like they say, “follow the evidence”.

    Not that I’m saying that the evidence strongly points in that direction. However there already is some eyewitness testimony that suggests it is possible.

    While there is much logic and reason in your argument, there are other factors to consider. The aircraft body usually is fairly effective at reducing EM forces from entering the aircraft. Range/proximity is also a big factor, aircraft usually stay hundreds or thousands of feet a way from transmitter towers. So even though you’re transmitter towers are definitely admitting more power, the power that enters the aircraft is not necessarily as strong because the tower transmitters are farther away and shielded by the aircraft body.

    Whereas a relatively low-power transmitter like cell phone located inside the fuselage of an aircraft might still be able reek havoc. It’s possible that a low-power transmitter located in the right place of the fuselage might act like a parabolic reflector focusing the RF at vulnerable electronics.

    However, like I said I am fairly skeptical of the RF interference theory, because the cell phones are fairly low power and aircraft electronics usually have very elaborate shielding. Though I would not entirely rule out the theory.

    I am fairly skeptical, but I think it is possible and worth some investigating.

    I think this is starting to go off-topic.

    However, should those claims of sub-standard work be true, and it having being reported and then the company continuing to use the facility then there is a fundamental problem in company procedures at the most basic level.

    On the contrary. I think you are going off-topic; by making the off-topic argument when the point I was making is substandard parts or repairs is obviously some of the possible causes for this mishap.

    There are claims that the pilots claimed that the throttles did not respond to auto commands or manual input. I assume the 777 design is an electronically controlled/assisted throttle. Therefore if the claims are true it strongly suggests that there was some sort of software, hardware/electronic or wiring problem.

    I’m hinting that the crash investigators should thoroughly check all the suspect components in the chain of failure to make sure that they are authentic and haven’t had any substandard/botched “repairs”.

    Some say there might be a fuel contamination problem, however I’m highly skeptical of that. From the descriptions I have heard, I strongly suspect there was some sort of electronic, electrical, sensor or software failure or glitch.

    A lot of these problems can be intermittent in nature, and very difficult to diagnose/replicate in some cases.

    At least it didn’t crash and burn; hopefully there will be enough evidence survive to find the source of the problem. Was it a generic software or hardware failure?

    Or is it more sinister? There have been some alarming cases of counterfeit parts showing up in the aircraft industry. There also has been an increase in fraudulent substandard repairs that approach the level of sabotage. IMAO

    Boeing 747-438 Emergency escape path lighting wiring incorrect repair. Ref 510004809 Emergency escape path lighting inoperative. Investigation found that the feeder cables had been cut (suspect during carpet laying) and had been incorrectly repaired using metal staples. Personnel/maintenance error. Incorrect repair. Investigation continuing.

    It will be interesting to see what the findings are.

    But then experienced aircraft engineers who have been around a bit will tell you that many US designs are structurally flimsy compared to their European equivalents.

    On the contrary. Are you joking or are you really that ignorant or are you trolling? :rolleyes: 😉

    The F-15s that were grounded had some parts (longeron) that were severely below design specifications in thickness and in smoothness that allowed ridges and valleys in a way that concentrated stress that accelerates fatigue. It was a manufacturing and quality control oversight.

    RAF engineers on exchange who were exposed to the L188 and P-3, and to the C-141, found aircraft whose vulnerability to fatigue problems were shockingly new.

    The main fatigue issues in the P-3 had been traced to a substandard batch of parts of Canadian aluminum that did not meet the design specifications. The aluminum was not the proper grade.

    The de Havilland Comet, had some of the first major fatigue issues and is used as an example to consider fatigue issues in design, manufacturing, testing, and inspection. So should I be like you bash the British and Canadian aviation industry? Not I. While I might criticize the mistakes I still have great respect for the industry and products.

    If you have a landline, you could always hook up your modem and try to update your security software, via a landline. I would be tempted to call your ISP and see if they would temporarily lets you hook up to update your software. Otherwise you have to use a landline and an auxiliary ISP.

    Otherwise I would suggest a full format and reinstall, which is about the only way to to be fairly sure to get rid of most malicious software.

    If you back up any of your files, you have to be careful that you’re not reinstalling the malicious software. Hopefully you backed up your software before you were infected. Otherwise you have to bite the bullet or risk installing the malicious software. If you try/risk to reinstall files that were backed up after you became infected, it would be best if you scanned it with updated security software before installing.

    Beware, not all security software checks for Trojans. Even some of the best security software out there will miss a lot of Trojans and other graywhere. I would stay away from sites that offer porn, hacks, ect…. be very cautious of free stuff. It’s often a trick.

    Some of the sites that spammers are spamming contain malicious software that is similar to a virus, that is frequently called a Trojan horse.

    This is an example of one of many of the Trojan horses that is at web sites that some are spamming.

    Trojan Horse: Zlob

    The “Video ActiveX Object” download is supposedly necessary for viewing porn at certain websites, but it is a harmful Trojan Horse program from the Zlob family, which will infect your computer with adware that harrasses you to buy worthless, bogus “security” software from the WinFixer gang. You will also find this fraud scheme used with “Image ActiveX Objects” and “NewMediaCodec.” Avoid them.

    Most antivirus programs DO NOT detect these Trojans. So use your common sense and STAY AWAY from risky types of websites (warez, cracks, serials and porn), because antivirus software probably won’t save you from embarrassing and dangerous infections.

    Simply visiting a compromised Web site can cause infection if certain browser vulnerabilities are not patched.

    I don’t know if you can or not, some hardware seems to be optimized for some types of compression and codexes. I would experiment.

    I use the mediacoder for when I need to toy with advanced settings (codexes and lossy and other compression settings), but its not too user friendly and complex if your like me and don’t have much of a clue. It probably has addwear in it, but hasn’t given me any problem yet

    I don’t know if it has the format you’re looking for. I don’t have an Ipod.
    http://mediacoder.sourceforge.net/index.htm

    Exactly, why ?

    Unless you are using the system to make a sound analysis, where you can’t afford a loss for technical reasons, the compressed audio files you are using nowadays won’t sound any different to you than the non-compressed audio.

    Often I can hear a loss with compression

    Six years to catch them and that’s considered oversight?? Software could have caught it at the first occurance and flagged somebody. As for delaying things the only time things would get held up is for stuff like this. If this kind of thing is happening so often that it would hampen the war effort to slow it down then there are REALLY problems.

    The other way of looking at it is that our dependency on software and automation is part of what made the fraud so easy to get away with and for so long.

    In some companies I have worked for you have to have a purchase order number to make any purchases, it is required tell a human what you are buying, what is for and how much before they will give you a purchase order number,so you can place an order/make a purchase.

    It wasn’t computers that caught this fraud, it was human oversight that caught the fraud.
