That sort of thing could increase a vessel's crew requiremtns - wouldn't you want to have a pilot and navigator on deck at all times to navigate through jumpspace?
It does. On the other hand, for a typical adventuring party it is a good chance to cross train. If I was GM I would say that a character who was cross trained this way might have a 0 level as pilot or navigator. Allows them to cover a watch with the caveat that something happens they need to hit the alarm and get the qualified personnel on deck.
Just my thought
