#early aviation
- Aeroplane piloting — A rare historical term used during the early days of aviation to designate the art, technique, or act of navigating and piloting an aeroplane. This structural concept evoked the collective practical knowledge related to controlling fixed-wing aircraft, being later completely replaced by the modern term 'piloting' or included within the broader scope of aviation.
- Avtolet — An archaic or regional hybrid term, used ephemerally in the first half of the 20th century (influenced by Slavic/Russian terminology), to designate an airplane, aircraft, or self-propelled flying machine. It represents an early linguistic attempt to name aerial vehicles, combining the Greek element 'avto' (self) with the Slavic root 'let' (to fly), quickly eliminated by the French-derived neologism 'avion'.
