According to these definitions the transition layer is 0–500 feet (0–150 m) thick. Aircraft are not normally assigned to fly at the "'transition level'" as this would provide inadequate separation from traffic flying on QNH at the transition altitude. Instead, the lowest usable "'flight level'" is the transition level plus 500 ft.
The highest altitude obtained by a paper plane was previously held by the Paper Aircraft Released Into Space (PARIS) project, which was released at an altitude of 27.307 kilometres (89,590 ft), from a helium balloon that was launched approximately 80 kilometres (50 mi) west of Madrid, Spain on October 28, 2010, and recorded by The Register's ...
An aircraft can stay aloft only by constantly traveling forward relative to the air (rather than the ground), so that the wings can generate aerodynamic lift. The thinner the air, the faster the plane must go to generate enough lift to stay up. [16] At very high speeds, centrifugal force (Kepler force) contributes to maintaining altitude.
Humans have managed to construct lighter-than-air vehicles that raise off the ground and fly, due to their buoyancy in the air. An aerostat is a system that remains aloft primarily through the use of buoyancy to give an aircraft the same overall density as air.
The Cessna 172 Skyhawk is the most produced aircraft in history.. An aircraft (pl.: aircraft) is a vehicle that is able to fly by gaining support from the air.It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, [1] or, in a few cases, direct downward thrust from its engines.
A Curtiss NC-4 became the first airplane to fly across the Atlantic Ocean in 1919, crossing with multiple stops via the Azores. Of the four that made the attempt, only one completed the flight. In 1923, the first successful commercial flying-boat service was introduced, with flights to and from the Channel Islands.
Planes can withstand the weather. Next time you’re flying through turbulence, look out the window at the wing. You’ll notice it flexing. It’s supposed to do that.
Cruise altitude is usually where the higher ground speed is balanced against the decrease in engine thrust and efficiency at higher altitudes. Common narrowbodies like the Airbus A320 and Boeing 737NG cruise at Mach 0.78 (450 kn; 830 km/h), [ 2 ] [ 3 ] while modern widebodies like the Airbus A350 and Boeing 787 cruise at Mach 0.85 (490 kn; 900 ...
