>I think you're best off waiting for the future efforts of Messrs Chafe, Crenier and Hetherington... :)Totally agree with this!

You guys seem to be missing the point. At the moment the Ariane IVSI/TCAS gauge is the only one of it's type that is fully featured. There are many packages that show traffic ie; PSS 777, 744, airbus pro series, Dreamfleets greatest airliners 734 etc etc, but thats all they do is show traffic. I also remember reading that PIC 767 "might" be upgraded in the future and there was no mention of creating a fully featured IVSI/TCAS simulation for that upgrade, and Lee has said he isn't certain that he will upgrade his IVSI/TCAS gauge as he has spent many hours in front of his pc for version1 and will need to find the time to spend many more for an upgrade. Now with that being said the Ariane gauge can be used on "any panel" and I have found it to function very well and when a RA is issued it is really nice to have the aural and vsi commands present. For me it adds that much more realism to my simming experience. It does look like the DF727 package will have a fully functional IVSI/TCAS system from the preview pics that I have seen for the analogue panel version, so with all the AI packages available these days and the online flying experience getting more and more popular it is nice to know that TCAS simulation is heading in the right direction.Regards,Van LatendresseYeoDesigns/AFG Group

"You guys seem to be missing the point. At the moment the Ariane IVSI/TCAS gauge is the only one of it's type that is fully featured."Point now taken, Van ;-)Actually, PS1, too, has an almost fully featured TCAS and has had for quite some time (it's really only missing a test function). The Aerowinx website has an overview of the programming which has gone into the PS1 TCAS. Whether the RA's in PS1 are better/worse than the one's in the Ariane gauge, I wouldn't be able to say without extremely specific tests.TCAS alerts in the real world are somewhat rare (many of them being false alarms... at least before version 7 came out), but I'd imagine that the pilots in the MSFS world are not so disciplined and would generate a few more warnings :-) In the real world, you get your money's worth, because you get to live, but in the FS world, it may be a little harder to get your money's worth unless you actively go hunting for intruder airplanes to test your TCAS system.And speaking of false alarms... For a while, we were getting false indications not unlike those which Tom is experiencing in FS(with an intruder aircraft positioned right on top of your own aircraft). I can't, however, recall what modifications were carried out to the aircraft systems to prevent this.Avoiding intruders can be a perilous exercise. There was a DC10 (or was it an MD11, I can't remember) which made an extreme control reversal into/out of(?) Hawaii when making avoidance manoeuvres... and buckled some of the control surfaces (It is possible to damage the aircraft by pushing/pulling too hard... I don't know if pilots are taught to avoid this... as the alternative, crashing into the intruder, has much nastier consequences). I'm proud to say that the substantial damage overlooked at the previous line station was picked up by Qantas engineers, here in Sydney.Anyway, I'm rambling again, so...Cheers.Ian.
