    Ah the SX owners club. I got some great info when I was a 200SX S14a owner.:cool:

    Autopilots have flown aircraft to destruction before you know.

    Air NewZealand DC-10
    Air Inter A320
    American Airlines B757

    To name a few.
    All flown into hills/mountains due to the Autopilot being incorrectly set.

    The AP is only as good as the data it is given. It is not the saviour and incorruptable tool you seem to think it is.

    In those cases the AP was only doing as it was asked.

    In every one of those cases a human was involved in making errors.

    When it comes to carrying out Cat 2 or Cat 3 approaches then the AP must be used.

    Hmm, but does the FMC nav database communicate with the EGPWS system nowadays to prevent automated CFIT?

    The EGPWS gets its position from the FMS; the recovery is still manual. No reason why it couldn’t be made automatic from a terrain caution though. Is there any reaon why a TCAS RA avoidance manoeuvre couldn’t be AP coupled either? Windshear recovery and GA manoeuvres can be so why not others?

    As to silly little Airbus Ind. joysticks: I don’t like them. I don’t think standard yokes are ‘macho’ (unless you are flying a C-47 or C54 for Buffalo Airways!) but I feel they take away from a pilot’s ability to retain his/her instinctive, hands on, stick-and-rudder senses – action memory if you will. Maybe the same thing can happen with a dumb little joystick but I am a pilot of the old school and I just wouldn’t much like to fly an aeroplane with such a minimal control yoke. Call it a possibly flawed personal opinion.

    I’m not trying to pick an argument , I am genuinely interested in why you dislike the Airbus joystick. It controls the aircraft, same as a yoke, the Airbus has no need for trim as it does it for you so control position as a reference is irrelevant. When the autothrust is engaged the thrust levers don’t move either. The lack of a yoke has the secondary benefits of giving a better view of the large CRT/LED displays and there is a very handy tray in front of you. 🙂

    I get the impression that those that are brought up on Boeings hate the sidestick, those that have flown Airbus love it. Have you flown an sidestick equipped Airbus?

    Watched Chris Morris’ satire about Muslim suicide bombers last night.
    Only someone like Morris would tackle this but there are many really funny moments. Brilliant.

    Amiga 500; you may choose not to reveal your credentials in this discussion but your answers show little understanding of modern airliner operation. From your answers I would guess you are not a pilot, at least I hope not anyway.

    As far as the

    stupid little joystick control

    is concerned, maybe VeeOne could explain to me what his objection is? On a FBW aircraft it most definitely does not need a large manly control yoke – it simply isn’t necessary. It only moves when the pilot moves it – same as the thrust levers.
    The computer systems that have proved invaluable are endless; TCAS, EGPWS autopilot, FMS, auto -pressurization, FADEC etc. etc. All these things and many more have enabled huge strides in aviation safety if not directly then certainly indirectly. Thankfully these are not likely to be “uninvented” any time soon.

    Oh, no. They know. They definitely know.

    But due to “politics” they cannot come out and say it.

    Ignoring a stall warning for a full minute?

    Catch yourselves on. The pilots screwed up – big time.

    Altitude is an inferred reading and airspeed is an inferred reading – both susceptible to external effects on the aircraft.

    Aircraft pitch and throttle/thrust are not. It is not unreasonable to expect people whose core damn job is knowing how to fly an aircraft to know that.

    Thrust is definitely affected by external factors. Thrust lever position on an Airbus tells you nothing if the autothrust is engaged.

    Gust upsets in extreme weather can put aircraft in all sorts of attitudes.

    Nobody is saying the crew weren’t to blame, all that is being said is that we do not know exactly what happened and despite your adherence to some sort of conspiracy theory, you don’t either.

    Maybe I am being unfair

    Yes, you are.

    Maybe you could help us out with your insight as to what actually happened on the flight deck of AF447. The authorities seem unclear as to what the circumstances were but you seem to be very sure.

    Possibly, but we don’t know what else may have happened. It was in an area of extreme weather so an upset of some description is a possibility.

    Being able to hand-fly an airliner at high altitude is one thing, coping with emergencies is another. Coping and dealing with emergencies is a large part of the type rating, it is expected that pilots know how to fly and in many cases they are found wanting – this is not a fault of automation but a fault of training and of how pilots are recruited.
    Pilots practise landing with minimal instruments and the minimum electrical supplies. That’s what simulators are for after all.

    Like others I have no idea what went on in AF447, but blaming the crew seems a cop-out to me. I think it was classic accident with many things seeming to happen together, one of which on its own would not have caused the accident. There seemed to be so many failures such that most if not all crews would have been overwhelmed.

    I greatly respect the skill that the crew US Airways 1549 demonstrated but they had the advantage of a nice day and an operational instrument and flight control system.

    The problem would be what drills would they practise? Accidents tend to be unique in their circumstances; e.g. who would have thought an A330 could be landed without engine power? Perhaps if the pilot had understood the systems better he wouldn’t have dumped all the fuel overboard.

    Many if not most modern aircraft are designed to be flown by the autopilot. That is certainly true of the Airbus A320/A330/A380 family and of the 777 and I would imagine the 787. Some phases of flight must be flown by the autopilot; cruising in RVSM airspace and Cat 2 and 3 approaches.

    They can be flown manually but generally the autopilot will make a better job. Systems have been automated to such an extent that navigators, radio operators and flight engineers have become redundant. This level of systems automation along with increased reliability has, I believe been largely responsible for the vast improvement in airliner safety in the last 50 years. There is still a way to go yet though.

    But what would you train pilots to do? What set of circumstances do they need to train for? In the simulator there are certain drills that are practised but how can you train for the unexpected? If a pilot lacks the basic skill to recover from a stall condition or indeed allows that condition to develop then I’m afraid that is down to training or lack thereof. Modern aircraft have systems that are designed to stop situations from arising and as I said before they are largely successful.
