"If you like I can point few "reliable" Ork Weirboys who might just possibly do the trick, for a price off course"

So if I understand this all correctly, as I don't have SoI yet, solar system can be compartmentalised to innersphere, biosphere; where life is possible and outersphere.

And there is RAW that traveling through, one forementioned, spheres takes about week. So if planet to where I'm traveling is in biosphere closest to innersphere, it would take me 2 weeks. But If said planet is in the outer reach of biosphere it would only take me week(+few possible days).

But it might be possible to make these travel times shorter/longer if said spheres contain fewer/more planets. Not included off course the gravity tides, asteroid belts and other stuff that might affect the travel. As for faster ship reducing time needed to travel cross system, I don't touch that subject until I have SoI in my calloused hands.

Yes or No will do.

For a "yes" or "no" to do, you'd need to ask a simpler question. :P

SoI gives systems three zones: Inner Cauldron, Primary Biosphere, and Outer Reaches. Each one can be Weak, Normal, or Dominant. The rule of thumb is that traveling from the inner to the outer edge (or vice-versa) of a Normal zone takes 2 weeks. A Dominant Zone takes roughly 3 weeks. A Weak zone roughly 1 week. If you're planning to visit a planet in the middle of the Primary Biosphere of a typical system, you should expect to spend about 3 weeks in transit from the edge of the system to the planet itself. Ships can theoretically travel faster, but it puts so much strain on the engines that it's better not to. 

The amount of planets in the system doesn't matter, only the size of the zones. A system could have Dominant zones with nothing in them, for example. Gravity Tides, Asteroid Belts and similar items may have an impact if you have to avoid them.

For your answer I would say that it's one of those Yes, because it gave me all the information I needed and was asking. No less, no more.

So let's say Outer reach is dominant (travel time 3 weeks), bioshere is weak (1 week), and Inner cauldron is normal (2 weeks), no additional asteroid belts or gravity tides to slow ships. Total travel time for mass conveyor arriving from differend solar system would be 6 weeks to reach inner cauldron mining planet that produces and refines ceramite and another 6 weeks for travel out of the said system. +- time needed to load, refuel and possible "recruiting".

On the other hand another mass conveyor just traveling to gas giant, situated in outer reach inner edge, takes just 3 weeks to get it's goods.

I still would possibly reduce said travel time regarding the placing of target planet in said zone. If it sits on the outer edge it would be greatly reduced but if it's middle or near inner edge it might be less reduced or full travel time to reach it.

This discussion is making me think I should show the average travel time to and from a planetary body from the edge of a system in my system generator…

As horrible it is to do science onto rpgs, I confese to have done some math.

Assuming:

1.viper scout hull (11 speed), archeo modified mezoa plasma drive (+2, from HA), (bq) secondary reactors (+2),  energy conversion matrix (up to +5), gravity sails (+1), adjust speed manuoever (up to x2, so now its 46), flank speed (assuming good rolls + 12, so 58) and finally stacking the deck (also maximizing, so +20 = 78);

2.and legality of this built;

we got 78 VU(!) speed, it's 156 VU per hour = 1.560.000km/h

and so, if my math is ever and still correct, flight from Neptune to our Sun, with that speed (almost 1,5% of speed of light), will take aprox 120 days.

Space is huge and I'm happy ffg haven't consider ships speeds into calculating inter system travel times.

You can probably assume that most space combat happens at a slower speed than regular travel. Perhaps it takes a while for the ship to reach maximum speed, something you can't get when turning back and forth in battle. Perhaps the amount of power the plasma drives have to divert to weapon systems restricts the ship's speed. Maybe the power output of a ship at full speed would make them extremely easy to target for enemy ships.

There is also the very real possibility that you would arrive on the opposite side ('far edge') of the system from the planet you wish to reach. This means you might, for example, have to traverse the outer reaches, primary biosphere, inner cauldron, inner cauldron again, then roughly half the primary biosphere again and then there's also some surcharge in time (perhaps one week) for leaving the solar plane (you didn't actually fly through or really close to the star did you?). That's about ten weeks if all of the zones are of average size. This is just as likely as arriving on the 'near edge' of the system

BTW, I still prefer the BattleTech option of jumping to the star's Zenith/Nadir so that you're above/below the orbital plane and can always plot a direct route. It avoids the issue of whether you're on the same side of the system as your intended destination. If using this method, it might work best to reverse the order of travel - so Inner Cauldron then Primary Biosphere, and finally Outer Reaches for inbound flights. Traveling to/from the Outer Reaches would take longer while traveling to/from the Inner Cauldron would take less time this way (although it's still WAY faster than the conventional method if you happen to enter the system on the 'far side' of your Outer Reaches destination). Travel to the Primary Biosphere - being that it's in the middle - would be largely unaffected except that you need not worry about arriving on the 'far side' of the system from your destination.

In order for ships to engage in combat, they need to have matched speed and direction to a large extent. The dance of space combat is done at low relative velocities and distances.

If one side does not wish to engage, then there is a Stern Chase.

I am not an expert by any means but if we were to look at travel outside of combat should we not look at the ships velocity in Gs as stated in the profile if we were to add relative math and science to a 40k universe rather then using combat speeds?

Ain't expert either, my point was that I'm happy with FFG don't taking each hull speed into account. As to grav acceleration - I can do some math, but physic is beyond me. To be honest I don't like the idea of 3-4 weeks, just to slow imho.

I'm not sure if - let's say grand cruiser can travel with 1,5% of speed of light or more anytime, but I don't get any source about this so won't argue.

I read somewhere that there's craftworlds intersystem speed mentioned in one of the printed adventures, somebody can confirm?

Well, the science is all done already :)

I recall that thread was a lot of fun and oddly enough some of the calculations roughly match the estimates from the new book of course not taking into account individual ship speeds just average speeds.
