Hi,
In the old days before INS etc. we used to "plot a course" which meant "measure the intended track between two points on a chart". We observed our "track made good" (by Doppler drift angle and heading / or back bearing from the beacon we'd flown (count the dits and dars from Polonis Consul beacon etc.) and did several course corrections (changed heading a bit) until we'd settled on the intended track.
