This entire argument is a joke. You're looking at a passage in the WCIV novel that is specifically written to *avoid* this issue and pretending it's somehow offended by the Wing Commander movie.
That alone is crazy: the movie simply follows the trend established by many other sources. The novels introduce jump capable Ferrets, Sabres... Super Wing Commander introduces jump capable Rapier IIs and Hornets... Wing Commander Armada introduces jump capable Arrows, Phantoms, Banshees, Wraiths and Gladii... Wing Commander II introduces jump capable Morningstars.
The movie having a jump capable fighter is not some shocking new problem. If anything, the movie is the first instance where they try to *downplay* the abilities of a regular fighter with a jump drive, giving it a very limited amount of fuel and a short life support period... heck, the novel says that because the fighter has no NAVCOM Angel couldn't have jumped Charybdis at all without Blair leading the way.
Then add to that the fact that the Wing 4 novelization is clearly worded to avoid *specifically this argument* in the first place, throwing out the weird "deck fighters" clarification... and then on top of that the fact that you're suggesting that a licensed novelization is somehow more right than a movie written and directed by the series' creator... there's just so many layers of nonsense here.
... and then you're consciously avoiding the most obvious fact, which is that one of the ships in question was Maniac's Hellcat, which Blair should certainly know doesn't jump. Stop harping on this, it's not getting anywhere.
