Adding a separate answer I felt was necessary because the 2 dimensional view is irrelevant. There is not just an x and y axis there is also z giving a 3rd dimension and I woukd have to research but, the nav or navigation device needs to arrest all movement in space befor the the jump to light speed so that the ship travels on one line and is not drifting with yaw, roll or pitch. Also, it seems for the sake of hyperspace the main thrusters must be facing directly at the 6 in clock terms for hyperspace to be accomplished. After all as Han Solo said you would have a really bad day if the nav system did not compute a safe trajectory and you fly into a star or supernova. Thankso for the consideration.
