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.
Flight envelope diagram. In aerodynamics, the flight envelope, service envelope, or performance envelope of an aircraft or spacecraft refers to the capabilities of a design in terms of airspeed and load factor or atmospheric density, often simplified to altitude. [ 1][ 2] The term is somewhat loosely applied, and can also refer to other ...
Ceiling (cloud) 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. Ceiling is not specifically reported as part of the METAR (METeorological Aviation Report) used ...
Produced. 1952–1962. Number built. 744 [ 1] The Boeing B-52 Stratofortress is an American long-range, subsonic, jet-powered strategic bomber. The B-52 was designed and built by Boeing, which has continued to provide support and upgrades. It has been operated by the United States Air Force (USAF) since the 1950s, and NASA for over 40 years.
Coffin corner (aerodynamics) 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.
Cabin pressurization. Cabin pressurization is a process in which conditioned air is pumped into the cabin of an aircraft or spacecraft in order to create a safe and comfortable environment for humans flying at high altitudes. For aircraft, this air is usually bled off from the gas turbine engines at the compressor stage, and for spacecraft, it ...
Number built. 68. Developed from. Boeing 707. The Boeing E-3 Sentry is an American airborne early warning and control (AEW&C) aircraft developed by Boeing. E-3s are commonly known as AWACS (Airborne Warning and Control System). Derived from the Boeing 707 airliner, it provides all-weather surveillance, command, control, and communications, and ...
The ERCO Ercoupe is an American low-wing monoplane aircraft that was first flown in 1937. ... Service ceiling: 13,000 ft (4,000 m) Rate of climb: 550 ft/min (2.8 m/s)
