many thanks Kevin for your replay.
I follow your info but not found nay flghtplan saved in any folder.
Now i try to complete a new fltpln but no help.
Any time that i try to save a fltpln, the fmc display first:
folder- 777
right lsk- confirm.
i push exe. and appear the name of fltpln but nothing in any folder.
Now i try to load again from PMDG the complete pack.
Thanks for your info from a old B767 maintenance man.
If you have other suggest, many thanks again.
