Pronunciation

  • UK: /ˈɔːtəʊˌpaɪlət/[1]
  • US: /ˈɔtoʊˌpaɪlət/[1]

Etymology

It is formed from English auto- + pilot,[2][3][4][5] probably as a shortening of automatic pilot.[2][4] The OED compares German Autopilot, recorded from 1934 or earlier and probably taken from English.[2]

Earliest recorded meaning

A device that steers an aircraft automatically: Merriam-Webster dates the word to 1916,[4] the OED to 1917, in the proceedings of the second Pan American Scientific Congress,[2] and Etymonline says it was first used of airplanes.[3]

Semantic evolution

The longer automatic pilot was used from 1897 for a small electric boat sent ahead of a ship to warn it of obstructions, a sense that soon died out; in 1916 it was first used for a device that keeps an aircraft on a set course, and in 1928 for one that keeps a ship on its heading.[2] Autopilot took over both technical senses.[2][4] The figurative use, for acting from habit or routine without thinking, is recorded for automatic pilot from 1955[2] and for autopilot from 1967,[2] mostly in the phrase on autopilot;[2][4] Etymonline dates this use only to 1996.[3]

Timeline

  • 1916 – a device that steers an aircraft automatically.[4] The OED's first record is from 1917.[2][3]
  • 1967 – figurative, automatic or mechanical behaviour, chiefly on autopilot.[2] Etymonline dates the figurative use to 1996.[3]
