In aviation, a round-robin flight is a cross-country flight which starts at one airport, travels to several other points for fly-over or touch-and-goes, and returns to the airport of origin. Such flights are often flown for cross-country training purposes.
This practice was adopted by sailors petitioning officers in the Royal Navy (first recorded 1731) .
The term round-robin is recorded in English much earlier, although not with the above meaning. It first appears in 1546 (with meaning unknown) and appears later applied to a category of person (precise meaning unknown): "These Wat Tylers and Round-Robins being driven or persuaded out of Whitehall" (1671). In a recent poll, the term "Round Robin" was voted #61 of favorite phrases used.
