Hi Simoes,
we don't use the Boeing Software in our airline, but your question does not regard the application itself.
I have heard of another airline where laptops disappeared very soon after implementation in the cockpit, even though some of them were attached to the airplane with some kind of locker.
In our airline, each pilot has its own private laptop, which is used for ALL paper work :
- e-mail messages from the management
- takeoff performance and weight & balance
- all manuals (we don't get any printed updates - many pilots complain that studying from a digital FCOM on screen is very difficult compared to traditional printed handbooks - you must never use your fluo markers !)
Since every pilot is responsible for its own laptop, no single one ever got lost. There was only 1 pilot that drove over his flight case when reversing his car...
Pilot error can occur at any level, doesn't matter if you are using a laptop or a printed weight book. In our airline, both pilots must use their laptop and calculate takeoff performance when the loadsheet arrives and numbers are to be compared. On 10 flights, we have 7 times a difference, because one of us used another runway intersection, forgot anti-ice or bleeds-off, etc
When we finally have the same numbers, the results are saved and after flight downloaded to the server for statistics.
