FSX flight planning involves more than drawing a line between airports. This hub covers the built-in Flight Planner, VFR and IFR routing, direct GPS and airway options, cruising altitude, NavLog information, and where saved PLN files are stored on modern Windows installations.
It also addresses FMC import failures, incompatible plan formats, folder permissions, waypoint naming, and navigation-database differences between FSX and add-on aircraft. Answers written and tested by the Fly Away team explain how the planner estimates headings, distance, time, and fuel, while identifying where those figures are simplified. Readers can therefore diagnose rejected routes and understand when a plan must be converted, rebuilt, or entered manually.
