FSUIPC5 is an add-in for Prepar3D Version 4 which provides an interface
for other programs to read and write all sorts of pertinent data
relating to the simulation, and in many ways even to control the actual
process itself.
It is an essential
ingredient in many add-on FS programs, and, in fact, may be installed on
your system by any one or more of them already. For most such programs
you do not need to actually purchase FSUIPC5. That deal, for their
access, will often have been already done by the add-on program makers.
But,
in addition, FSUIPC5 contains a number of useful features for you, the
Flight Simulator user, features that can assist you setting up the best
simulation environment and making the best of what you have. It can do
this because, by its very nature as an interface program, as a “puller
of wires and pusher of switches” on behalf of external applications, it
is also in the best position to help you do the same.
