Air Mobility Command, which accounts for 20 percent of all avionic fuel usage by the United States federal government, is experimenting with autopilot changes to find the best tradeoff between the reduced drag of 'vortex surfing' and the resulting 'ride qualities' of flying through another aircraft's wake. Though it is currently used mostly for military purposes, what restricts it … This content is imported from {embed-name}. Talking about followers : we are teaming up with @flyfrenchbee @SAS @DGAC #DSNA @NATS and @eurocontrol, to show how our #fellofly demonstrator can fly 2 aircraft safely together, reducing fuel burn to contribute to the industry’s #sustainability goals. Just kidding. NOAA Photo Library. Most people would say that they do it to save energy, which would be right. Canada geese, ducks and swans commonly form a skein in V formation.[3]. ... You love badass planes. The upwash assists each bird in supporting its own weight in flight, in the same way a glider can climb or maintain height indefinitely in rising air. True turbulence is more like the way fall leaves follow and swirl in circles after a car passes through, because cars are not as aerodynamic and are usually interacting with more complex surroundings. A V formation is the symmetric V-shaped flight formation of flights of geese, swans, ducks, and other migratory birds, improving their energy efficiency.

Unlike wake turbulence, jetwash, which is an umbrella term for the massively propelled air and gases that flow out of jet engines, is definitely highly turbulent. ✈ You love badass planes.

One Airbus-based startup concept thinks so. Squadrons of planes can save fuel by flying in a V formation, and many scientists suspect that migrating birds do the same. [4][5], Media related to V formations at Wikimedia Commons, This article is about the flight formation of birds. America's Aircraft Are Barely Ready for War, Intelligent Life Can't Exist Anywhere Else, The Epic Quest To Build a Better Airplane Wing. Geese flying in classic V formation. Let’s use an analogy everyone understands: Top Gun. Why do some birds fly in a V? In the concept pushed by the Airbus incubator, appropriately named “fello’fly,” planes line up over a mile apart, which is still close enough to benefit from the wingtip vortices generated on either side of the lead plane. Think about driving a small motorboat when a yacht or even a cruise ship passes and being swamped and tossed around in the larger boat’s wake. For the military aircraft formation, see, USA Today: "Why birds fly in a V-formation" by Traci Watson, "'Vortex surfing' could be revolutionary. [1] All the birds except the first fly in the upwash from one of the wingtip vortices of the bird ahead. V formations also improve the fuel efficiency of aircraft and are used on military flight missions. It's really nothing to do with close formation," explained Dr. Sandra Bour Schaeffer, CEO of Airbus UpNext, in an interview with CNN Travel. The Vic formation is also common in ceremonial flyovers and airshow flights. When airplanes push through the air at high speeds, they generate something called wingtip vortex, also called wake turbulence, even though it’s not true turbulence at all. The V formation possibly improves the efficiency of flying birds, particularly over long migratory routes. In the movie, Tom Cruise practices extremely close formation flying, and the climactic events are caused by something the characters refer to as jetwash.
