So what is that "back up" again? Exactly what job outside of working in aviation are you going to do?
Hey Mr.Hat, first of all, I respect your position as someone who has been there and done that.
The "back-up" that I believe people may be referring to is with regard to using your Bachelor of Aviation, as entry into suitable post-graduate study in an
alternative field. Many may also find that their B.Av may entitle them to RPL in other fields at undergrad level.
