Hello! I am posting the same question also in this area of the forum because I don't know where is the correct position .
I am quite new of PlanG and using it since few days. I have the following problem: when creating a flight plan on PLAN G and changing PASSING ALT on different waypoints  ,then try to save as .pln to export to FSX, I am able to write the altitudes on the corrispondent boxes but it does not save the PASSING ALT. When I load in FSX I dont'find my ALT. but just those generated automatically by FSX. If I reload the .pln plan into PLAN G  I can read blank; it seems to be possible only saving the plan under extension .plg. But FSX imports only the.pln plans and so it generates automatically the altitudes being impossible to change them. How can I do? Am I doing something wrong? My task is to have my vertical profile defined by me case by case in the flight plan Many thanks in advance and best regards
