pb84,
I suggest you have a look at X Plane 10
X-Plane 10 Global | The World?s Most Advanced Flight Simulator | X-Plane.com
This is not IR practice, but if you want some really challenging flying, try
Condor: The Competition Soaring Simulator I recently bought a joystick, which has transformed my Condor experience.
Today I was ridge soaring in Snowdonia followed by a 200 km cross-country in the Czech Republic. A tricky one because one of the turning points was over 6000'!
I managed that one just, and then became cocky on the final glide and "fluttered" my wings off.
