Grid Option

Just as a point of order, Boeing offers a Grid option for the 777/747 and 787. It displays on the ND but has no LNAV navigation capability.

So grid navigation is not used very frequently, I assume.

I guess that if you use True North navigation, then near the NP you fly great circle tracks between each two waypoints, as computed by the navigation systems, while seeing how the heading changes (without any roll), right?
