I see that there is a link to most of the SIDs, STARs, and approaches for the US for use in PIC767 FMC. However, I am just wondering, aside from the large amount of disk space, would having all these procedures have an effect on frame rates, loading, RAM used etc while flying?On a related subject, I recall that someone had created a program that swaps only those selected database files needed into the FMWCP folder and keeps the others somewhere else to help speed up these operations. However, I cannot find the name of it or a link in this forum, does anyone know where it is (and should I use it)?Thanks for your help.Damon

Damon,Yes, if you have them all in one dir. it will affect performance.Have a look at the last message in this thread.http://ftp.avsim.com/dcforum/DCForumID33/1857.htmlKind regards,Stephan Haas
