I think I would have to agree on the d2 minimum for those 'basic knowledge' skills - If I think about it in terms of Catie's case in particular, I wouldn't be surprised if there was mandatory courses regarding emergency knowledge of how to pilot/land/etc. Wouldn't be enough to do fancy maneuvers or anything like that, but would be enough to know how to land the ship in an emergency, or emergency jury-rigging to be able to land in the first place.
To add to that... Catie has Eidetic Memory, so she can potentially remember those emergency procedures.
To conclude, it makes sense to me. Maybe even part of the crew manual (Ody, we *do* have a manual for each crew member, right?

)
