--I can honestly say that, at a minimum, 95% of what I learned in school was worthless. And, even though I'm a college graduate (3.7 GPA) - if you were to give me a 7th grade history exam, I would fail.--
I honestly think you are wrong. I'll show you why.
--In fact, I'd probably fail most 7th grade exams.--
Not if you studied. I probably still couldn't pass one.
--something I picked up from books while going to school.--
So that English you took was worth something after all.
While you may have forgotten most of the details, what college did was make you a well rounded problem solver. I have seen people that have more technical ability than I do at work for the same job, but they just took technical classes at a technical college. They can't even begin to do all of things I can because some of it had to be invented. If they run into something they haven't seen before, they have no idea how to find the answers. I agree some of it was BS. We'll so is some work. I'm actually grateful for some of those BS classes. Now I have an improved BS detector because of it. Also, your 3.7 GPA taking classes that you are not interested in shows discipline.
--I'd go so far as to say the *vast majority* of students are not learning for any particular reason at all. In the lower grades, they do what they are told. By college, most of the students, particularly the ones that are going to graduate - have selected a major that is going to lead to a job that will both pay their bills and be tolerable.--
All of this is sad but true, but it doesn't mean that can't go into it without a plan. I do not think that you can just take the stuff that you are going to use at your job and get by later that way, especially if your job involves problem solving. I had good teachers and bad ones. I had to learn how to deal with the bad ones. At first I didn't appreciate this, but now I've kinda got a little different outlook on it. This even taught how to deal with bad situations at work and in life as well.
Discipline is just as important in making it in life as the 3R's. Sometimes it's just as important what you wont do than what you will do. Grades being fairly high in all classes does show to a future prospective employer that you might show up on time. Just getting out of bed a making to the job is half of the work.
When, I went to K through 12 showing up could affect your grades. When I went to college, things changed, and most of the time if you knew the material and just showed up to take the test, you would get a good grade. Now, college is like high school basically because the government will not fund tardiness. I'm not sure about private schools as I never could afford one and it didn't seem to help your chances of finding work. Liberal Art's and things like that are worthless here.
But I guess I'm a little older. When I was 11 I could walk and chew chewing gum at the same time. When I was 11 I could light firecrackers without blowing my fingers off. When I was 11 I was trusted with a 22 rifle. When I was 11......
--I suspect the Boeing design reflects the American legal system. If the plane goes down and it is the pilot's fault, you can sue the pilot. Maybe you can even sue the airline who trained him. On the other hand, if the plane goes down and the pilot had no control then you can sue the aircraft manufacturer. Never mind that the design saves lives - better to allow thousands to die at somebody else's hands than one to die at your own. Gotta love the tort system.--
I suspect you are wrong. Boeing has used FBW since the 777. It comes down to implementation. I think you will find if you read that both the Airbus and the Boeing designs take a slightly different philosophy. Which one is better? We'll I think the jury is still out on that one. I think the crash record of both companies planes are about the same. And the US invented FBW. The first vehicle to use it was the lunar lander. Then of course the military used quite often in the F-16 and F-177 and everything else from the 1980's on. Airbus had the first commercial airliner to have it I believe, but Boeing picked up on it later on. The first airbuses had an interface problem like the lunar lander without enough pilot feedback.
--For the same reason we'll allow tens of thousands to die every year in auto accidents due to driver error but we'd never consider automating driving because maybe somebody might die every year or two due to a computer error.--
Maybe, but our streets really are paved with gold and despite what you hear on/.,wherever you are from, your country pales in comparison with what the US has |-)
BTW, that was just a joke, but seriously, have you seen the death toll on the streets in China, or India? They are worse than the US in the 60's (about 60,000 per year). Now we are down to (below 40,000) with much more drivers. There is no car culture in China, the J walk, ride bikes, drive, walk, drive cattle, where their traffic is. Now I must admit Germany is even better in this area than us because they actually make you have to have some kind of training to drive. No cell phones. No lane radios, and good lane control with high speed.
--However, if computers had control, then many other flights which have crashed killing all on board would have been avoided. Plane crashes are virtually always either a) mechanical error or damage (such as the Hudson landing), b) weather/micro-burst related (such as Air France), or c) pilot error - either making the wrong decision, misinterpreting the information the computer was giving them, or blatantly ignoring the advice of the computer and resulting in a plane crash. There are very few incidents (if any) where computer control of an aircraft has led to its crash.--
I think this can be traced back to a lack of "feel" by some FBW systems. It causes pilot error. Of course it wouldn't matter if all pilots were like Neil Armstrong. I don't think the Lunar Lander would have landed in one piece if he had not taken control. For the less experienced pilot that has not seen combat, more thought has to be given in the design of the of the interface between the human and computer. You could actually be flying upside down in a thick cloud and thing you were right side up if you just trusted the seat of your pants. I think this is why a computer was ignored in one of the cases that you mention. The pilot ignored the computer because of the g-forces on his ass, the stick control was still light because of FBW so he didn't trust the computer. I think there should be some form of mechanical feedback in the stick and rudder pedals. A computer can simulate this as well.
Just watched the news. They have redundant sensors too, but they could have all iced up if designed wrong. I doubt if the real cause will ever be discovered unless they get lucky and find the FDR. Airbus has probably suspected the sensor and tested it under very extreme conditions and it may have iced up. So they are not taking chances. I could have even been a meteor strike
--Good point. Disclaimer: I am a former Air Force avionics tech, F-15 TISS. Military fighters and civillian airliners are different beasts but I understand that the F-15 had a quad-redundant (trivia: the transporters in Star Trek: TNG have quad-redundant buffers) flight control computer.--
Not to nitpick you, but I understood the F-15 Eagle to not have FBW. The first plane that I heard of having FBW was the F-16 Fighting Falcon. Just curious, what F-15 models have FBW? Maybe the E model? I don't think the A model had that when it came out.
BTW my uncle worked on planes back in the early 60's when jets were new. He said they were esier to fix than cars. My dad was in Japan after the occupation mostly taking engines out of P-51's that "inexperienced pilots" crash landed, testing the engines and putting them back in other planes. That was all he really did. He said blue smoke came off of the propeller tips. That's something that is missed in the old camera footage and something I have never seen.
Anyhow, I was just interested. The F-16 has to have FBW just to stay up in the air but the F-15 does not because I know the A to C models did not have this originally. As far as that goes the last 747's might have FBW, but I'm not sure.
--Laugh if you will, but all those software design processes you were taught and all thoe iso compliance rules were not invented by computer scientists. They were borrowed from the airplane industry. There are methods to engineering that work and they learned these by error.--
This is true. Like the checklist a pilot uses before he takes off. In business or anything else this works way better than relying on memory and guesswork.
Maybe the airbus doesn't have any user feedback from their FBW systems, I don't really know. A little feedback on the stick and rudder can be simulated with stepper motors and a simple computer. Lack of feel can make the pilot not trust the computer when he should or trust it when he shouldn't but that feel can still be added into a Fly By Wire system.
--2) Do FBW systems provide sufficient feedback for a pilot to feel the plane? Could accidents be avoided in cases like this by adding additional feedback?--
I think they did this in the case of the F16. It's FBW but has a small amount of feedback on the stick and rudder.
Yeah, it used to be that you had to have a lot of copper wire in a transformer for a power supply to work that converts AC to DC. Now you don't even see that, just a bunch of transistors. Yep, transistors can do almost anything now and they are cheaper than copper. So I don't get why this stuff is so expensive. In the US there must just be small cottage industries making solar setups. They buy the panels for a manufacture that probably has a lot of hand work involved while in Germany they use robotics and flow soldering machines to make the panels. All of this stuff could be done cheaper.
We'll of course Bling will out do Yahoo because Bling is shiny any Yahoo is noisy. Shiny trumps noisy. But...Google trumps them all, we'll because it's like you know a really big number and people like big numbers.
I think we wanted one like that, but saw no reason to pay for it, so we just made up another name. A little later the domain ran out on the squatter and it was free as well. I would check and see how long he has it for. If it is just about to run out then you may be able to snatch it then. Domain names should cost a little more to slow this practice up. I blame Godaddy here.
I think there is a lot of delusional people on both sides of the Atlantic. The UK was surrounded by sea and it would have been hard, but if the Germans would have concentrated on the airfields for air superiority instead of retribution bombing of cites, I think they could have made it work. Hitler was arrogant and didn't think the UK mattered much anyhow. Limbaugh, Dr. Phil, Opera, reality shows etc. really suck. But, you have similar stuff in the UK. I haven't studied up enough on France to know if there is anything similar there. I do know that there is just as many if not more tabloids in the UK as the US.
Limbaugh is real prick IMO. He wanted all people on drugs punished severely, but because he supposedly got addicted because of his back being operated on, I suppose that is OK. He still has a lot of elderly people fooled over here but not me. He is just a plain ordinary junkie. IMO jail is an expensive an infective way to solve that problem. He has no right to criticize anyone, but still does and it is a damn shame that some listen. MOD me down but he is just a shade above a Neo-Nazi to me.
Wasn't he delusional and French? They did, however make some poor tactical decisions as did the UK. The UK was harder for the Germans to get to or they would have conquered that country just as easily. The Germans may have even still been able to pull it off if they hadn't done the stupid thing and invaded the USSR. I don't think the French are a bunch of surrender monkeys. In fact I think they maintain more nuke than any other country in the EU. I wouldn't mess with them.
I don't like them as well as the the old jeep. Maybe it can go in deeper water, go over bigger rocks,etc. but they are expensive and they get hung up on four wheeling trails that an old CJ 7 Jeep or Toyota 4WD pickup can pass. I had a 94 Toyota that could make it through trails a hummer couldn't. A guy around her got his H1 stuck in between two trees. I would say old towns would have the same issues. Of course a military hummer can drag more stuff with it than the old small jeep but you could carry quite a bit with those jeeps as well, but what if our government spent less money and gave every other infantryman a four wheeler off the shelf from Honda or Yamaha. I just think a Hummer is to damn wide. Build more Strykers for something that size and get something small and handy off the shelf.
Not if the corner of the triangle is active. It does look bad but I swear it makes sense somehow. If the software went for the key that has the most touch on it, it may not matter how they are shaped. I bet you could go faster with this thing than a motorola razr.
If it is for a small touch screen like on an iPhone it completely makes sense to me. I t keeps you from touching the wrong key. It would be more of a texting thing I would think.
