Report the value of flight route and flight level in General Discussions Posted April 18 I see now where you are aiming at , sounds like the database would need something like a Navigraph/Navdata upload each month and a process like PFPX where you can re-check all your route information each month. Of course if one wanted to share the routes with other Virtual airlines then a hosted PHVVMS library of the routes could be done as well.  Virtual airline maintain their own routes  Virtual airlines can deposit routes or take out routes from a 'global' shared database if they want to do so . I see it that way where everyone if they want can share their knowledge through the routes they build and maintain . Having good routes helps everyone running a Virtual Airline as well as those pilots who connect with Vatsim etc. I do not work in Aviation despatching but I can see similarities to freight logistics which I have worked on software to do with planning deliveries and schedules to meet customer needs and driver legal hours driving regulations.
