It certainly seems like an undue load (no pun intended) on the pilot to require entering multiple components for weight correctly. From the article linked below I am no longer sure how much automation is [...]

A GPS certainly makes life easier — and although I think many of us might consider what would happen if we were without it or it was unable to identify where we were, it is less often we consider how it may lead us astray.
