Thanks Tnick, It's a pretty good idea, if my pilot put in comment the real aircraft, I'll be able to do the same thing than you by editing the PIREP.
For the Live Map, I have tried kAcars only and my skin is the default crystal without any modifications.
During the flight, the acars in the database with kAcars give without problem the long / lat so, is kAcars compatible with the Google map ?
Thanks again, I'll try tonight to put a snapshot to illustre this subject.
