Hi,I am looking for an American VA that has an automated, freeware PIREP system. Meaning that I do not have to note down myself the departure and arrivel times, distance, fuel used, etc...Anybody any suggestions ?

Well, you'd have to use an ACARS logging tool of one sort or another...

I'm sure there are some that offer FS ACARS integration. FS ACARS is freeware but it's not that great. There are VA's that use payware programs like FS Flight Keeper and FS Flight Tracker, but they cost a whopping $12 TO $20.
