'aviatic' originates from French 'aviatique' (19th century) ultimately derived from Latin, specifically the word 'avis', where 'avis' meant 'bird'.

'aviatic' changed from French 'aviatique' and the modern English adjective was formed in analogy with 'aviation' (from French 'aviate' / 'aviation') and Latin roots; the progression moved from Latin 'avis' → French 'aviatique' → English 'aviatic'.

Initially it was formed with the sense 'pertaining to birds/flight' (via Latin 'avis'), and over time it evolved into the modern meaning 'relating to aviation, aircraft, or flying technology'.
