Not a pilot in any respect however...
As much as the documentation on this incident points to a manual error and whilst I am glad it was not a tragic outcome - I cant help but feel that more could have been done to avert this situation from a systems point of view.
I am not for a second criticising the crew although it would appear from the report that a large element of the blame seems to lay there. My concern is simply mis-typing one digit into a laptop or during transferring the data to the FMC is what is alledged to be what has been the fundamental underlying issue.
As a software developer myself and not a pilot this seems to be a case of the software and procedure biting the crew in the ass. In my own personal opinion the crew is not so much to blame as the procedure. Humans may not intend to make the odd typo here and there but we do, and yes we should be double checking and triple checking things but it is a fact of life when we look at things we tend to see what we expect to see not what is really there (check this if you want to see how good the mind can be at correcting what is actually there with what you expect to see
Do You Have An Amazing Mind?) - we can be our own worst enemies without even knowing or realising it quite easily.
I think the aviation industry should not just be concentrating on what the errors were with what was entered in the FMC but more with how the software can deal with such erroneous entries. For a start eliminating the step of transfer from a laptop to the FMC would be good but it would be better if the the FMC could (maybe it can I dont know) check that the parameters entered are acceptable with axel weights - Pressures on the axels would not have to be that accurate and could probably be easily measured on oleo movement all that would be required would be an acceptable margin.
Apologies for my tuppence worth but I think the problem highlighted is alot bigger than pilot error. As the saying goes - to err is human, to really cock things up requires a computer (add in a few stages in between and your asking for trouble).
