cf. How Jump works (Doulos version - DEPRECATED)
<aside> 💡 WAIT!!!! But, if jump drive is fueled by a pellet, where do they acquire those? How much do they cost??
This causes a problem with skimming a gas giant - it could not provide fuel for the jump drive. I think I'd better say they can manufacture the fuel pellets on board.
No, better yet, the jump drive draws off ten tons of fuel (per parsec) into a separate tank and then begins the reaction.
This is far from perfect but I can't think of something that makes more sense.

Here's how jump works in my world and we will go ahead and say that all you you know this conceptually and the scientifically-minded surely understand it more.
First, a jump course is programmed into the NavHelm.
Second, the jump is initiated when a fuel pellet is injected into the jump drive reactor the Jump Drive draws fuel into the Jump Drive Reactor.
This begins a thermochemical reaction that, once started, can't be stopped - it will complete the cycle no matter what, which causes constantly increasing acceleration until a gradual depletion of fuel causes a gradual reduction of acceleration.
Ten tons of fuel are exhausted after about 140 hours (5 days, 20 hours), having traveled about 1 parsec. Twenty tons of fuel are required for a jump of 2 parsecs and the reaction ends after about 180 hours (7 days, 12 hours) A jump of three parsecs takes about 200 hours (8 days, 8 hours) and requires 30 tons of fuel.
Your Jump Drive is rated 3 and cannot travel further than that in a single jump.
All estimates are +/- 10 hours, so the bridge is manned at T-10 hours before estimated time of dropping out of Jump. Jump Exit Countdown timers are present all over the ship - they start automatically when the ship enters Jump
Outside communications/scans are not possible in Jump.
100 hours (4 days 4 hours)
120 hours = 5 days
140 = 5 days, 20 hours
160 hours (6 days 16 hours)
180 = 7 days, 12 hours
