The service ceiling is the maximum altitude of an aircraft during normal operations. Specifically, it is the density altitude at which flying in a clean configuration , at the best rate of climb airspeed for that altitude and with all engines operating and producing maximum continuous power, will produce a given rate of climb.
Coffin corner (also known as the aerodynamic ceiling [1] or Q corner) is the region of flight where a fast but subsonic fixed-wing aircraft's stall speed is near the critical Mach number, at a given gross weight and G-force loading. In this region of flight, it is very difficult to keep an airplane in stable flight.
In aviation, ceiling is a measurement of the height of the base of the lowest clouds (not to be confused with cloud base which has a specific definition) that cover more than half of the sky (more than 4 oktas) relative to the ground.
Displayed in the U.S. Capitol Rotunda, the Frieze of American History detail The Birth of Aviation depicts Leonardo da Vinci, Samuel Langley, Octave Chanute, and the Wright Flyer ' s first flight. Upon returning to Kitty Hawk in 1903, the Wrights completed assembly of the Flyer while practicing on the 1902 Glider from the previous season. On ...
The Lockheed U-2, nicknamed "Dragon Lady", is an American single-engine, high altitude reconnaissance aircraft operated from the 1950s by the United States Air Force (USAF) and the Central Intelligence Agency (CIA). It provides day and night, high-altitude (70,000 feet, 21,300 meters), all-weather intelligence gathering. [1]
Ultralight aviation (called microlight aviation in some countries) is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and conventional three-axis control aircraft with ailerons , elevator and rudder , calling the former "microlight" and the latter "ultralight".
So why does the United States have a debt ceiling? And how did it pass into law? To understand how we got here, it helps to know where we've come from. The origins of the debt
An airplane (North American English) or aeroplane (British English), informally plane, is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. [1] Airplanes come in a variety of sizes, shapes, and wing configurations .
