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.
March 6 – The last flight of the SR-71 Blackbird takes place, when Lieutenant Colonels Ed Yielding (pilot) and Joseph Vida (reconnaissance systems officer) fly U.S. Air Force SR-71A serial number 61-17972 from Palmdale, California, to Washington Dulles International Airport in Virginia, setting a Los Angeles, California-to-Washington, D.C. world record time of 1 hour 4 minutes 20 seconds at ...
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.

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]
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
The US Aviation CAVU (named for the aeronautical meteorology term meaning "Ceiling And Visibility Unlimited") is an American high-wing, strut-braced, single-seat, open cockpit, single engine in pusher configuration, ultralight aircraft that was designed and produced by AeroDreams of Manchester, Tennessee, but marketed by US Aviation of St Paul, Minnesota under their brand name.
