I also failed to notice where the altitude change was stored in FSX, even though the superb instructions issued with ADE included a statement preceded with "IMPORTANT". Thanks for the heads-up.

Hello Art,I feel better now that I know someone else missed the placement of the altitude change file. As soon as the AVSIM Library is back on line, I'll upload a corrected package.Dan

The corrected version of GCFV which includes the altitude file has been uploaded. It can be found in the "What's New" section of the File Library. The old version has been removed. Again, sorry for the goof.Dan

Hello Dan,Thank you for uploading the new files. Now everything looks fine.Patric
