[Thanks Rapier for your help.
I found also some information about IR missile 
in Falcon 4.0. If you have Falcon 4.0 it's ok 
if you don't, go and buy it. It helps a
lot to understand various concepts.
Thanks again

Hi Tiger,
Yes I have Falcon 4 and it is amazingly close to the real thing.  I also have F22 ADF which is another great and very realistic game (both completed).  Overall 1600 hrs of sim experience.  The book which comes with Falcon 4 is also great, it does show you some good tactics even some which pilots are not willing to discuss but the best way to learn is to fly because even I have learned new tactics which I have studied and impoved to good effect.
