    So what your suggesting is using C++ like C and you'll get the same performance .... how interesting.

    Why not just use C in the first place (large set of experienced developers to draw upon)?

    FYI commercial vs. non is a matter of a 777 vs a little single prop cesna which yes they are both aircraft and they both fly but other than that they are worlds apart.

    All I said in my first post was that the guys reasons where flawed ... which they where.

    I think systems to aid in flight and to give advice are the way to go. I'm sorry I gave the impression I was behind the idea of taking control away.

  19. Re:The real question is ... on Automagic No-Fly-Zone Enforcement · · Score: 4, Insightful

    Maybe I was a little harsh but the points I made are still valid. How many hours have you logged in a modern day commercial airliner 777 , A320 (We are talking about commercial fly-by-wire systems).

    As for the weather I full understand looking out the window is very important. but can you really tell that much about which way the wind is going when your 200 miles off? If your in a bad weather cell that different. (but at no point in my post did I say the pilot should not be able to fly his plane)

    As for the signifacant changes due to an engine lose ... well i've been down in the code for an FMC dealing specifily for those type of situations ... so yeah I truly understand your aero dynamics and flight capability changes but ... it still doesn't change the fact that its a fly-by-wire system most of those things are handle for you by the FCC and FMC (we are not talking about a piston driven AC but rather a 777).

    See I understand in emeregence situations autopilot is not a substitute for a pilot. At the bottom of my post I said I hate the idea of taking the control out of the pilots hands. I also freely admit computers are not perfect and that why pilots routinely change setting in the FMC to make it do what the pilot wants

    I will give you the point that the computer may not make the right descion and there should be a way to take control away from the computer. You also have to admit that there are times where the pilot wont make the best descion (see the crash in swiss airspace where the pilot went against his TCAS and people died because of it).

    I ask you to find one thing in my post where I said the pilot should not have the ability to break away. Hell I know computers aren't perfect and I agree a 100% that taking control away is a bad idea. I just disagreed with your reasons because they weren't applicable to current commercial jetliners.

    As for responsibility of hundreds of lifes, your right I have not been up there with the lives in my hands but before my current job I used to write ATC systems which are mission critical (in production in germany) so I do full understand its not kids play and that when things malfunction you put lives in danger.

    I think you had the right idea your reason just where off. And I'm sorry if I offended I was probably a little harsh but I didn't agree ande I need to post on it.

  20. Re:Technology just becoming "mature"... on Automagic No-Fly-Zone Enforcement · · Score: 1

    TCAS has been in use for a while in commercial aviation as well. But as you know can have problems like the crash in swiss airspace (it was over germany but the airspace is actually controlled by the swiss.) Not to mention TCAS works by broadcasting intent rather than exact position like GPS. Note: the TCAS system didn't fail but one of the pilots didn't fallow the advisory but the other did

    I'm on a project right now that is looking to extend the TCAS idea out to 30 minutes (TCAS is 30 seconds). Its definetly the direction things are going to go in 20 years.

    I agree with you in the idea that removing control from a pilot is a bad idea but I disagreed with the reasons he gave.

  23. Re:The real question is ... on Automagic No-Fly-Zone Enforcement · · Score: 4, Informative

    How this got modded to insightful is beyond me because you know nothing about commercial aviation. I'll try and speak to a few of your points.

    There's considerations of how bad the weather may be in one direction

    How do you think the pilot knows of bad weather ... oh thats right he gets ground reports through his computer ... (and if it comes from ATC it can be hand entered into the computer.

    which engine may have failed causing difficulty in turning in one direction,

    Currently all the new aircrafts coming out are fly-by-wire (777,A320,A380) so the computer has to handle this already. Further more how do you know which engine is out without the computer (the insturments are run by one of the myriad of computers on board).

    which heading the aircraft needs to be on after completing a turn to line up with the desired runway so as to make a landing the first time

    First of how do you think it work now 99% of the time you are in the air the FMC is guiding the plane including *gasp* your headings out of turns towards your runway (yes I know the FCC is where the real control logic for the autopilot is but it tries to fly to what the FMC is telling it).

    how critical is it to get to a certain altitude rapidly

    You know what the FMC is going to be able to calculate out how fast you can and can't climb a hell of alot better than any human (yes I know you can do a general calc of how fast you can climb based on your gross weight / alt / airspeed / and your possible thrust but you can't do it nearly as accurate or quick so would you really want to?)

    Now mind you I dont like the idea of taking away control from a human because computers can fail (I know there are 3 FMC (well the new 777 is actually a different cabinet setup but you get the idea)) and I want a human watching. They get paid rediculous money so let them do their jobs.

    So next time before you do some arm chair piloting get your facts straight.

    If you have those kinds of resources and intelligence agencies in your pocket why would you even go down that road? I mean with that kind of power you could get your hands on nuclear waste (even hospital grad stuff is nasty enough).

    As for the pilots if your speaking about 9/11 ... there is a huge difference between what they did and actually getting 747 off the ground and through the tracon. I mean changing the planes heading is actually very easy (I can do that) actually doing take offs require much more skill. (I know this because I work on a 777 simulation currently)

    And when you drop that type of cash on a plane it sends up red flags ...

    And how would you get it off the ground you have to file a flight plan and have real pilots.

    Maybe with a corp. front you could pull it off but as soon as you made the move you've just given up you front.
