- Robert,
- in general, you write extremely well argued and researched cases,
- but occasionally you spoil the whole effect by little "throw away" comments
- such as the above - history, even modern history is littered with comments from
- people writing off things as "science fiction", "can't be done", "will never replace
- the current ...." etc who have had to eat their words shortly after.
-
- Anyway, getting back to the A320 ...
-
- I suppose that I should now admit to not actually being a strong a supporter of
- this machine as might have been assumed from past postings (I have flown on
- them too many times :-)
-
- My concernes are not based so much on the ergonomic design, so much as the engineering
- of the computerised systems, and the numerous "cover-ups", which are apparently
- inspired by the French government - if you read French, you might be interested
- in a series of articles in "Science et Vie", which is a sort of "Scientific American".
-
- There, the concerns expressed are simply that:
-
- - There have been many documented occurences of sudden altitiude
- changes which were uncorrectable by the pilot.
-
- - Airbus Industrie REFUSES to let independent experts audit their software,
- that say that the control system can only be examined as a "black box",
- which either performs correctly, or it doesn't - anyone at all familiar
- with software engineering will recognise this as being close to garbage.
-
- - Refusal by AI to acknowlege that there may be problems at all.
-
- - Attempts by members of the French government to abort independent
- investigations (including that of Science et Vie).
-
- This is getting away from our discussion about pilot contributions to "incidents",
- but if you want to knock the A320, there are much better grounds for doing so
- than ergonomics - without the more serious design problems, there would probably have
- been many fewer "accidents", and hence less reason to blame the ergonomics.
-
- Besides "cosmetic" issues like tactile feedback, and some layout issues, the 767
- is pretty close to an A320 - as you have said (I think - sorry if I misquote you)
- the 767 is just more conventional in cockpit design - its a pity its automatic
- landing system can be as good as the best pilot on a good day, and a rough as
- the worst on a bad day ... usually more towards the latter ...
