Definition
A military pilot officially credited with shooting down five or more enemy aircraft in aerial combat.
Plain English
A combat pilot who has been confirmed to have shot down at least five enemy aircraft in air-to-air fighting.
Context Anchor
Seen in military aviation history, pilot biographies, museum displays, and combat records.
Derivation
From the playing-card sense of 'ace' meaning the highest or best card. French military pilots in World War I began calling a pilot who shot down five enemy aircraft 'l'as' (the ace), and the term carried over into English.
Intuition Check
Ace does not simply mean any very skilled pilot here. In this aviation use, it means a military pilot credited with five or more enemy aircraft destroyed in air-to-air combat.
