From Inventing aviation

"La navigation aquatique est une navigation dessus, la navigation aérienne est une navigation dedans. Sur l'eau; dans l'air." — Victor Hugo to Nadar 13-Jan-1864

Navigation is a general term for getting an aircraft to go where you want it to go.

"Aerial Navigation*" is a specific designation within the SUBJECT-MATTER INDEX. Particularly within that source, "aerial navigation" may pertain to virtually anything having to do with aviation. This also the case with reference to many French-sourced summary and title entries.

Aeronauts and aviators also engaged in navigation in its narrower sense, of finding their way from one place to another. Because they covered such long distances, microphotographic maps, and apparatuses to read them, were introduced to give flyers insight onto the territories they overflew.[1]


  1. Hildebrandt, 1908, Airships Past and Present, p. 193. "An instrument, called the microphotoscope, was therefore designed. It consists of two parts, which are quite separate from one another, viz, the eyepiece or magnifier, which is used in daylight, and a lighting device, which is used by night. The magnifier consists of a lens, which is so mounted as to be capable of moving in slots, either up and down, or to the right and left. Microphotographs, which represent photographic reductions of maps published on a larger scale, are taken on celluloid films, and mounted in position between thin sheets of glass, two inches square. The lighting arrangement contains a small electric glow-lamp and a battery, the lamp being switched on and off as required."
