I don’t think that is spelled out. Rather than ask it here, it deserves its own topic and then this could be changed to a link to that post, honestly. We can chew up the scenery on a subject like that and this topic isn’t meant to be for discussion.
Edit: I made a thread for this and here is the link.
@Hardwire asked this in the Ship Design Thread and I think it deserves its own thread, so I’m reposting it here.
What was asked:
Hello all, I am looking for information as to the cooldown of jump engines. If a ship has enough fuel to make 2 jumps how long must they wait after exiting one jump before they can enter another jump? I seen it somewhere but can't find it now. If you know what book and page this is discussed on I would appreciate it.
