Creating Flight Plans with Flight Planner and loading them to avionics through the EFB is a nice feature but it seems that not all planes support it. For instance, I have not been able to load a flight plan into a v35’s GNS 530 avionics or a 172 GNS 430.
Anyone knows if this is by design or is a bug? Is there any limitation on this feature?
