You got me curious. Can you explain?

Etymologically there's no good word for map (mappa meant napkin, charta meant a sheet of paper) but 'tabula' was used in Classical times.

Aeronautical charts extrapolate from this because being in command of an aircraft is really just commanding a different kind of vessel. Port, starboard, manifest, fix, captain, first officer, and hull are all valid aviation terms, for example, with roots in the sea. A chart is not a map.

Thank you! I'd have trouble explaining to someone what the precise difference is but now I can wear my consequentialist hat and explain that they are different because they are used differently.
