How do you use astromech's and their limited jumps feature

[worfbacca]

How do you use the limited jumps feature of an astromech or B-wing or A-wing. When the core book says they are limited to two or 10 jumps - what does that mean exactly? Can they only jump to systems which they have coordinates for stored in their databanks? Can they compute new coordinates on demand or do they have to do that with a Nav computer?

We always played this meant you could pre-program a number of jumps from one location to another. Our course, you had to get to the jump point that was programmed before making the jump. This helps explain how the Rebel fighters could execute hit and run raids so quickly and effectively.

Alternately, Han didn't have the time to get the calculation for the jump from Tatooine to Alderaan because they were being pursued the entire time - either by stormtroopers or star destroyers.

I have the preprogrammed jumps work both ways, so A-to-B and B-to-A still only counts as one saved jump. But like Bidlo and garhkal, each end of each jump has a specific entry/exit point in space. I'm ok with it being a fairly big area though, bigger than an Imperial star destroyer, so it would take something a good amount bigger or an interdiction field to all-out block an hyperspace entry point. So it would make sense that some of the preprogrammed jumps involve one or both of the same systems as other saved jumps, but have different entry/exit points so starfighters on missions have different options for escape from a system.

Well, this may not be a helpful answer, but I’m going to throw out the existing Navcomputer types entirely and replace them with a D based system that stacks with the crew’s Astrogation skill. Individual routes will have a Difficulty based on their Duration and how frequently traveled they are, then individual ships will get either a bonus or penalty to Astrogation when rolling to calculate the jump. An A-Wing or B-Wing would have a -2D or -3D rating, so their pilot would only be able to roll 2D on Astrogation, thus leaving out all but the shortest courses.

Mine is similar to others.

Short version:

I think of it this way - the jump is like a pre-plotted route.
It was calculated in a fully updated nav computer, and it created the trip specific route.
Then that was loaded into a droid, which can only hold so many.

Longer Version:
I think of a full on nav computer as like "google-galaxy" (google maps - star wars style). It has data on tons of stuff, but needs regular updates.
You can tell it a point a, and a point b, and a speed, and it will figure out the route.
Generating this route takes a lot of work - (from min to hours - depending upon your game flavor....).

Once the route is done - a very specific point a to a very specific point b, at a very specific time and speed - you can copy it to your droid.

But once in the droid - it does not have the power of the nav computer, nor all the data (like if your phone lost connection and could not reach google maps) and you could not make a different route.

Finally - I would say that full blown nav computers are very expensive and have other requirements - which is why they are not in smaller ships or droids. But that is just my own in-universe justification.

use what ever works for your game.

I always looked at Limited to X jumps is a Pre Programmed Jump Computer that must be Programmed before use.

it works as a nav computer only between pre programmed hyperlanes etc.

Where as a Normal NAV computer being more advanced and having already a library of listed and known jump points, and one that can constantly or as needed programmed from cockpit etc.

However I do consider a Coruscant to Aldreaan to Coruscant as three programmed Jumps with the limited jump computer.

this limits operations in a to me balanced way witha "short range" craft

Isn't that backwards. Nav coms ARE the ones making astrogation computations. Astromechs are the ones who store pre-plotted jumps.
