RE: [FT] Orbit and FT

>Using cinematic, you need to need to plan a hexigon that is larger than

planet. Then move at a speed equal to the length of 2 sides of the
hexigon
doing a 2 point turn each round. But then you have to account for
gravity.

  First, decide how long a turn is, how much acceleration gravity
provides, and the distance of a mu (eg 7.5 minutes, 1 gee = 1 mu/turn, 1
mu = 1000km).
  Then calculate gravity for various distances.  Oops!	Since anywhere
significantly above the surface of the Earth is going to have less than
1gee, this leads us to fractional mu.  Let's go back and make double the
turn length to 15 minutes, so now 1 gee = 4 mu.  Calculating the gravity
bands is left as an exercise for the student.
   Determine orbital circumference at various orbits, and divide by 12
turns.	Let gravity give you a 1 point change of direction every turn.
