Hi Tony
Sorry, my mistake, I should have said that all airac cycle data from Navigraph should go into the Custom Data folder, not the Custom Scenery folder, doh. My first lengthy response is correct, the second response is in error as far as this point is concerned.
On the other point though, all created flight plans whether written in Navigraph or Simbrief, all go into the Output/FMS Plans folder.
Apologies again for the confusion, I'm actually on vacation trying to do this from memory!
Regards
Paul
