This may have been discussed before in the forum, but it is unclear to me how fire arcs work in space fights.

Since you do not record the relativ positions of all spaceships involved in a fight (except for range of course), how does it matter that a gun is pointing forward or dorsal?

When does a pilot know whether she needs to manoeuvre her starship first before the crew is able to target a dorsal gun towards an eligible enemy?

How will the crew know whether there is an eligible secondary target in another position?

I might have overlooked something in the rulebook, but it will be really nice to understand the standard mechanics before we have our first game.

When dealing with non capital ships the fire arcs are largely there for narrative reasons, to give the gm a reason for a miss other then just bad aim. Capital ships are also there for narrative, but it plays a larger role as the gm is also expected to use that to limit the weapons a capship can bring to bear on a single target.

Typically if you are following RAW a pilot of a noncapship will never have to make a piloting check to get a weapon pointed at an opponent, the game assumes the pilot, just by being in combat, is already doing that.

Also remember a round in EotE is longer than other games, so in space/vehicle combat each round there's plenty of time in these untracked ongoing maneuvers for the pilot to move the ship to bring multiple weapons from different arc to bear.

I'm with Ghostofman on this. The starship combat rules don't deal with firing arcs, but I think they're just too narratively useful to leave out completely as WotC did in the Saga Edition.
