LoadingToAccel:

--------------------------------------------------------------------------
   Sail loading parameter to characteristic acceleration.
   The loading is the sail mass per unit area, m/A.

   Since version 7.
--------------------------------------------------------------------------
   Form:
   acc0 = LoadingToAccel( sigma )
--------------------------------------------------------------------------

   ------
   Inputs
