Explain fsd

I usually get these errors when I plot a route before I load my ship up with cargo.

Sometimes I can just re-open the galmap and it'll automatically re-plot the route and sometimes I need to manually re-plot it.
 
Once you get your head around what's going on its pretty simple. The max amount of fuel your FSD can swallow in a single gulp and its "optimal mass" depend on the size and grade of the FSD, as modified by engineering. How much fuel a jump uses up is a formula based on both the distance and your ship&cargo total mass compared to your FSD's optimal mass. If the jump requires the FSD to suck in more fuel than it can swallow in one go (or more than you've got in your tank) then you can't do that trip in a single jump.

The formula for fuel cost in a jump is not linear with distance, at the same mass and with the same FSD a 20ly jump will use up more than twice the fuel that a 10ly jump does. This is why the route plotter offers you the choice of "fastest" (fewest jumps) or "most efficient" (least fuel) - an efficient plot will usually get you further but require more jumps to do it. This can, for example, get you through a zone full of unscoopable stars without running out of fuel midway or allow you to extricate a ship with a short jump range from an isolated star system that it can't make it out of on a fast route.

As for Horizons being "worth it" or not, if you never want to land on a planet (for example, to visit an engineer to tweak your modules) or don't want access to all possible ships and gear, you can live without it. However, all future developments in gameplay will be based off that foundation so unless you're happy with what you have in the game now being all you will get, you probably do want Horizons. You might be comfortable staying a generation behind in the name of reduced cost, so be prepared to wait out the next major development cycle in the hope that Horizons becomes cheaper in the same way the base game did once Horizons was established but that could be a long and frustrating wait.
 
Your FSD is rated for a specific length of jump: they show you unladen (no cargo/fuel) range, current range, and fully laden range. So, for example your ship may be capable of 22 LY unladen, 17 LY currently, and 12 LY fully laden. So, depending on how much cargo and fuel you have, the range of your ship will vary between those min and max numbers, but the current one always tells what your functional range right now is.

You typically get that message because you set your path on the galactic map before loading your ship. Now that your ship's range has changed, that path is no longer valid. Reopen the galmap and it'll automatically adjust your route for you.
Yes that was an important note to make. Don't plan your route until you have your cargo on board. Hope many times have I plotted a route. Filled up my cargo. Left the station. Enabled FSD and got told I'm over the weight limit by 5 tonnes. Always plot route before filling cargo
