That would be easy enough to do, but on further reflection I'm not sure 
that it's necessary.
Fogged tiles and unknown tiles are practically the same - both may or 
may not contain an enemy unit.  So we would pass in a parameter to 
decide whether we can fly through unseen tiles at all.  The problem with 
this is that restricting a plane to only "seen" tiles probably won't get 
it very far!
We could come up with more complex logic - for instance, ocean squares 
are less likely to contain an enemy unit than land squares, so we could 
refuse to fly through any known/unseen land square but happily fly 
through a similar ocean square.  Under this reasoning, unknown tiles are 
different from known fogged ones.
I'm really not sure what's best here.  If we do allow parameters, what 
should they be?
