United States Air Force F-15C Eagles flying in a Vic formation over Alaska. Formation flying is the flight of multiple objects in coordination. Formation flying occurs in nature among flying and gliding animals, and is also conducted in human aviation, often in military aviation and air shows.
Studies on theropod dinosaurs do suggest multiple (at least 3) independent acquisitions of powered flight however, [1] [2] and a recent study proposes independent acquisitions amidst the different bat clades as well. [3] Powered flight uses muscles to generate aerodynamic force, which allows the animal to produce lift and thrust. The animal may ...
When viewing the formation from above, the positions of the planes resemble the tips of the four fingers of a human right hand (without the thumb), giving the formation its name. The lead element is made up of the flight leader at the very front of the formation and one wingman to his rear left. The second element is made up of an additional ...
The frequency range in insects with synchronous flight muscles typically is 5 to 200 hertz (Hz). In those with asynchronous flight muscles, wing beat frequency may exceed 1000 Hz. When the insect is hovering, the two strokes take the same amount of time. A slower downstroke, however, provides thrust. [8] [9]
In close formation the aircraft can have as little as 0.5 meters (1.5 feet) of separation between them. [5] In shows the team forms in the delta multiple times and planes on the edge of the formation break off for solo stunts while the central four stay together. Delta formation tricks are usually saved until the end of the show. [5]
Lesser flamingos flying in formation. When in gliding flight, the upward aerodynamic force is equal to the weight.In gliding flight, no propulsion is used; the energy to counteract the energy loss due to aerodynamic drag is either taken from the potential energy of the bird, resulting in a descending flight, or is replaced by rising air currents ("thermals"), referred to as soaring flight.
The two commercial flights, an Alaska Airlines Boeing 737 trying to land and a Skywest Airlines plane taking off from Portland International Airport, were flying during a storm at around 4.41pm on ...
Supersonic flight is associated with the formation of shock waves that form a sonic boom that can be heard from the ground, [10] and is frequently startling. The creation of this shockwave requires a significant amount of energy; because of this, supersonic flight is generally less efficient than subsonic flight at about 85% of the speed of sound.
