解析Flight envelope

Flight envelope refers to the range of altitude, airspeed, and other parameters within which an aircraft can operate safely and efficiently. It is typically represented graphically as a plot of airspeed versus altitude, with various boundaries indicating limits such as maximum speed, stall speed, and maneuvering speed. The flight envelope is an important concept in aircraft design and operation, as it helps pilots and engineers understand the capabilities and limitations of the aircraft, and ensures that it is operated within safe and optimal conditions
