<aside> đź“ť 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.
</aside>
First, a Jump course is programmed into the NavHelm.
Second, the Jump is initiated when 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. (It’s up to the pilot to decelerate.)
Jumps take about a week… 10 tons of fuel are exhausted after about 140 hours (5 days, 20 hours), having traveled about 1 parsec. 20 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 3 parsecs takes about 200 hours (8 days, 8 hours) and requires 30 tons of fuel.
<aside> đź“ť Your Jump Drive is designed to Jump no more than 2 parsecs.
However, McKay says that the previous owners made many modifications to the Jump Drive and it will certainly do 3 parsecs but the ship wasn’t originally designed for that, starting with the fact that it doesn’t have enough fuel storage for it to be practical. The ship can hold 42 tons of fuel and it requires 10 tons of fuel per week to provide normal operations power. “The drive will do Jump 3 but we’ll be running on fumes when we get there and we’ll have to run the whole ship at reduced power all week to even have the fumes.”
30 tons for 3-parsec Jump plus 10 tons for a week of power = 40 tons of fuel needed.
10 tons divided by 7 days = 1.43 tons per day.
At the end of a 3-parsec Jump, there would be a maximum of 2 tons of fuel remaining.
So, McKay is exaggerating a little but it’s still cutting it kinda close. You’d have to go straight to a starport or skim a gas giant.

<aside> đź“ť All estimates are +/- 10 hours, so the bridge is manned at T-12 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.
