Can anyone tell me if there is a TCAS add-on for the 777 and / or 737 - I have searched the net, unsuccessfully. I have always felt that this is a lamentable omission in 2002 and now 2004. I am no 'puter expert but I am sure that the technology which combined FS2002 and "JUSTFLIGHT", enabling an elementary collision avoidance system could be incorporated into the much more sophisticated nav systems in 2004 to provide a realistic TCAS display.
FSHotseat has this feature.
