Sorry about the deceptive title - this actually is on topic.
I'm gearing up to GM EotE, and am reminded of my beef with all Star Wars rpgs so far... they give you a 'crew' or 'ship's complement' listing. Sometimes it's just a number, sometimes (like with EotE) it's more detailed. Like they'll specifically say 1 pilot, 1 co-pilot, 1 gunner, 1 engineer, 1 loadmaster, etc.
So does that mean 'all these roles need to be filled by a separate individual' (in cases where there's a large crew complement), or does it mean 'only the listed crew can perform related actions' (where there's a small one)? Like, the crew complement of a YT-1300 is "1 pilot, 1 co-pilot", while the Firespray's is "1 pilot"; does this mean that the YT-1300 needs a pilot and co-pilot to be able to fly, or does it mean that additional crew aboard a Firespray may not co-pilot?
Similarly, if a gunner is listed, does this mean that the pilot may not fire the gun? Or alternatively, if a gunner is not listed, does it mean that only the pilot may fire the gun?
I've got a three-player team with their eye on the Firespray, which has a ship's complement of "1 pilot". Does this simply mean that a minimum of one character can run all the systems, or that only the pilot may run these systems, and the other characters may only effect repairs?
Sorry if this has been brought up before and I missed it, but this is one of those things that will come up again and again, so I want to get all my ducks in a row...
