The MSFS flight plan is still very incomplete… If were possible to edit the speeds and altitudes of waypoints to calculate the TOC, cruise and TOD it would be much better to have a more accurate idea of the plan, if we could create waypoints on the map and naming them, set altitude and speed would be perfect. Unfortunately we can only create but without customization. Yes I know you can make a plan on paper and pen, use a external software /addon and in fact I even like do it with pen and paper when I do VFR flights in the sim but I believe the simulator itself should have these options.
The NAVLOG that you open while flying is also a mess haha.
In FSX if I’m not mistaken you could customize the waypoints, when I started playing MSFS I was surprised that this feature didn’t exist. Just like the mouse yoke and so many others…
You’re not dumb, it’s the simulator that has one more incomplete feature.
