Eurasian cranes in a V formation (video) Birds flying in V formation. A V formation is a symmetric V- or chevron-shaped flight formation.In nature, it occurs among geese, swans, ducks, and other migratory birds, improving their energy efficiency, while in human aviation, it is used mostly in military aviation, air shows, and occasionally commercial aviation.
Canada geese fly in a distinctive V-shaped flight formation, with an altitude of 1 km (3,000 feet) for migration flight. The maximum flight ceiling of Canada geese is unknown, but they have been reported at 9 km (29,000 feet). [43] Flying in the V formation has been the subject of study by researchers.
Chesley Burnett "Sully" Sullenberger III (born January 23, 1951) is an American retired aviator, diplomat and aviation safety expert.He is best known for his actions as captain of US Airways Flight 1549 on January 15, 2009, when he ditched the plane, landing on the Hudson River after both engines were disabled by a bird strike.
The 2009 "Miracle on the Hudson" — when Captain Chesley "Sully" Sullenberger landed an Airbus A320 on New York's Hudson River — occurred after it encountered a flock of Canada geese, resulting ...
The word "goose" is a direct descendant of Proto-Indo-European *ǵʰh₂éns.In Germanic languages, the root gave Old English gōs with the plural gēs and gandra (becoming Modern English goose, geese, gander, respectively), West Frisian goes, gies and guoske, Dutch: gans, ganzen, ganzerik, New High German Gans, Gänse, and Ganter, and Old Norse gás and gæslingr, whence English gosling.
For larger birds, flying in flocks reduces the energy cost. Geese in a V formation may conserve 12–20% of the energy they would need to fly alone. [30] [31] Red knots Calidris canutus and dunlins Calidris alpina were found in radar studies to fly 5 km/h (2.5 kn) faster in flocks than when they were flying alone. [19]
Moments before the bird landed on the field, fans had spotted a flock of geese flying low near the stadium lights in a "V" formation. About 80% of birds migrate at night, preferring the cool of ...
Although their heavy weight affects their ability to fly, most breeds of domestic geese are capable of flight. Geese have also been strongly selected for fecundity, with females laying up to 500 eggs per year, compared to 5–12 eggs for a wild goose. [3] [5]
