OK so hopefully this isn't a dumb question or the answer is blatantly in the faq. So we all know Jan allows a ship to roll an additional die. If the ship can make multiple attacks such as a cr90 with its hard points do all of them get boosted. Before you give the quick no the card I believe says when a ship is attacking and not performing an attack. A cr90 shooting it's primaries and all of its hard points is technically attacking right?
Jan question
Nope. When you perform an attack, you are attacking. You are not still attacking if you perform multiple attacks, you are attacking multiple times.
From the FAQ:
RULEBOOK (PAGE 10)
The scope of a single attack is not defined. The first paragraph on page 10 should read:
“During this phase, each ship may perform one attack against one enemy ship. Starting with the ship with the highest pilot skill, to perform one attack, players resolve the following steps in order:”
It's easy to miss, though, being the second entry in the FAQ 
But seriously - one attack runs from Select Target to Resolve Damage. Jan's ability may be used for the scope of that one attack.
Thank you guys!!
