airworthiness
AIR-wor-thee-ness
/ˈeəˌwɜː.ði.nəs/
The measure of an aircraft's fitness for safe flight in accordance with regulated aviation standards.
Refers specifically to legal and technical compliance with safety standards rather than aesthetic condition or comfort.
The story behind the word. Coined in the early 20th century as aviation transitioned from daring exhibition flights to regulated public transport. Modeled directly on the centuries-old maritime term 'seaworthiness', it reflected the legal requirement that aircraft be certified sound before entering commercial airspace.
