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.
For instance, the aircraft described by the black altitude envelope on the right can fly at altitudes up to about 52,000 feet (16,000 m), at which point the thinner air means it can no longer climb. The aircraft can also fly at up to Mach 1.1 at sea level, but no faster. This outer surface of the curve represents the zero-extra-power condition ...
Title 14 CFR – Aeronautics and Space is one of the fifty titles that make up the United States Code of Federal Regulations (CFR). Title 14 is the principal set of rules and regulations (sometimes called administrative law) issued by the Department of Transportation and Federal Aviation Administration, federal agencies of the United States which oversee Aeronautics and Space.
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) ...
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.
The Civil Aeronautics Board (CAB) was an agency of the federal government of the United States, formed in 1940 from a split of the Civil Aeronautics Authority [1] and abolished in 1985, that regulated aviation services (including scheduled passenger airline service [2]) and, until the establishment of the National Transportation Safety Board in 1967, conducted air accident investigations.

Air transports for heads of state and government are, in many countries, provided by the air force in specially equipped airliners or business jets.One such aircraft in particular has become part of popular culture: Air Force One, used by the President of the United States and operated by the United States Air Force.
