Hello Stan, air navigation also used GC sailing!
Nowadays practical use of gnomonic charts is nearly over...
nobody improvises a GC route on the fly.
My program, and others, can export the GC/Composite sailing data in GPX format, to be used on an ECS, ...
Also OpenCPN has a built in tool to plot GC and obtain RL waypoints, (attached).
yes method 2.
