Firstly, terminology used here is generalised and not meant to reflect my lack of knowledge between the Airbus and Boeing systems!
I have a few payware aircraft and love the entire process of flight operations from flight planning to engine shut-down. The great thing about most payware is the ability to construct your own flight plans with SIDs and STARs and what not.
That said, I was wondering is there an flight management system available to use with default/freeware aircraft? And even better, is there a way to tie it into the nav data of a payware so that I don't have to rely on the default FSX flight planner?
Any help is much appreciated!
