Bruno,
We started with MS FS 2002/2004 then gave Xplane a try. After trying
out the Elite program when checking out a Flight school, we bought the
program along with the IFR training manual It was worth every penny and
more. We got our instrument ratings two weeks ago but still plan to
continue using it for practices before every instrument flight.
You can download the demo program (fully functional but with 5 minute
time limit) to give it a try. Aside from the IFR training syllabus,
Elite also offer Instrument approach scenarios which are also quite
helpful.
Regarding hardware, we started with a joystick and rudder pedals then
replaced the joystick with the CH flight yoke. The joystick worked OK
but the yoke seemed to be closer to flying our plane.
