Copilot is just about all you need for flying. I also use MobileDB for holding the ~10,000 waypoints I need for all the platforms, customer heliports, airports, hospitals, and centers of all the lease blocks in the GOM, often needed to get close enough to newly-arrived drilling rigs, seismic boats, etc, that I often need. Copilot just doesn't have the storage space for everything, plus it slows things down too much. But for most use, Copilot is all you need. Databases are available for most of the world.
