Hy All, i'm a total newbe of traveller, even if i own 10 different reiteration of the game i haven't never ever played or mastered a game.

Now i'm trying to convince a group of friends to start playing.

One thing that i can't untertstand fully is the 100d limit...

There is somewhere a table of the travel times to reach the 100d limit, maybe based on the UPP of the system?

or has anyone a fast rule to generate it? (maybe a x*y dices of hoursor something similar)

thank You!

I am using the Traveller Core Rule Book (2016 edition).

On p148, the rules state "A ship can only safely jump when it is more than 100 diameters distant from any object larger than the ship".

I used the formulae on p152 of the in a spreadsheet, to come up with timings to reach the 100 diameter limit, mainly for world sizes 1 to 10 (aka A).

The formula is:

Time = 2 x Square Root of ( Distance / Acceleration)

Where:-

Time is in seconds

Distance is in metres

Acceleration is in 'G' i.e. Thrust setting for the manoeuvre drive.

**EDIT** Acceleration is in G and a Thrust of 1 is 10m/s/s etc so when you do the calculation it should be:

Time = 2 x Square Root of ( Distance / (Thrust*10))

As an approximation, G is assumed to be 10m/s/s instead of the usual 9.8m/s/s

I am working on a Python script to produce a better quick reference table.

My calculations can be accessed as a PDF

Note: I calculate time taken in seconds because of my (limited) spreadsheet abilities, the figures for "Minutes" and "Hours" might not be what you expect. The columns for minutes and hours are probably best regarded as "ball park" figures with the number after the decimal point ignored.
