I found today this post in the Engauge blog:http://blogs.technet.com/engauged/archive/.../27/415129.aspxShe talks about the GPS variable list, but I found this too late... The link is dead and I can't get the list.Could some of you get it?If so, can you please post it here, I would like to get it as well ;-)Thanks,Eric

It's in the FSX SDK.

That's what I was thinking, but I am quite reluctant in dowloading 211 MB just for this...Thanks anywayEric

http://www.fs2x.com/Tutorials_files/FS2004...20variables.pdfThis was this original list.I don't know why the GPS lettering on the background is so intense. I hope you can read it.cheers,nick

Thanks Nick ! I had the similar list but taken from the .dll with no idea what was read/write without doing ALOT of testing..Thanx again!RomanProud "TEAM AVSIM" RTW race member.XP Pro, FS9, FR Locked @ 23, AMD 1800+ OCd to 1900+, APIC MProc Mod (24 IRQs), Latency Mods, ECS K7S5a V1.1, 7 fans, 1 gig, 100 & 60 Gig 7200rpm HD, ASUS/NVidia GeForce 64mb AGP on 21", NVidia FX5500 vivo 256mb (CRAP) on 18", Nvidia 93.71s ( The highest can go for the GeForce3 & 5500 combined ), Savage4 32mb on 15", BV services mods.
