Interplanetary Transit Ready Reckoner  
 

Transits from the M25 limit to the colony worlds are usually at 1g constant acceleration (or deceleration).  Transit times here assume constant acceleration - so once the ship reaches the M25 and enters Hyperspace, it retains its real-space speed. It then decelerates on arrival in normal space at the target system. Since speed can be altered whilst in hyperspace, this can be varied whilst in transit to fit the naviagtional requirements at the other end.

There is an expanded downloadable full version of the chart below, with slient running transit times as well as lower G movement times and shorter distances too. The file is in open document spreadsheet format.

Distance is down the side, constant acceleration is along the top.

Assumptions

1.  Read off distance to travel down the side, and acceleration/deceleration along the top.  The number in the table is days of travel time.

2. Constant acceleration / deceleration throughout the period .

3. One - way acceleration / deceleration for M25 to colony transit. For intra-system travel x1.5 transit times.
