The first is about plots, what determines the distance of my plots (The length I'm allowed to plot)? I do know about most economical and max jump, for me it's 1000ly and 5000ly. I was wondering if my fuel loadout and max jump range effected those numbers?
The second is about my fuel gauge, I have several fuel tanks giving me 2.43/h, what exactly does 2.43/h mean?
Sorry, I AM a n00b and still learning.
2.43/h is how many segments of fuel in your fuel guage are used every hour. The rate depends on many factors, but mainly your load-out and what modules are switched on. This usage is constant and independent of jumping. You have a line above the fuel guage, which is the working fuel tank. That line goes down at the rate of 2.43 times per hour, and each time it reaches zero, it steals another segment from the fuel guage and replenishes itself, so it will go from full to empty and repeat 2.43 times per hour. I'm not sure if a segment is 1T. I believe it is, but somebody needs to confirm it, as I've seen some evidence to suggest it isn't.
The 2.43 is completely independent of how much fuel or how many fuel tanks you have. It's the rate of using fuel without jumping. The more fuel you have, the more segments you get in the fuel gauge. The fuel guage has constant length in the HUD, so if you have a small amount of fuel, you can see the separate segments, but when you carry a lot of fuel, the segments are so short, you can't differentiate them.
When you jump, each jump takes fuel directly from the fuel tank. The amount is shown in blue before you jump and depends on the length of your jump, which FSD you have, your ship and it's load-out plus other factors like super-charging the FSD.
You can reduce the 2.43/h by switching off un-needed modules, like power distributor (after setting pips), shields, limpets, weapons, SRV, cargo hatch, and all the stuff like that - basically everything you don't need for flying and jumping. That also has a big effect on heat generated, so greatly lengthens the time you can scoop fuel without over-heating.
