The outer edges of the diagram, the envelope, show the possible conditions that the aircraft can reach in straight and level flight. 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 Mach number at which these effects appear is known as its critical Mach number, or M CRIT. The true airspeed corresponding to the critical Mach number generally decreases with altitude. The flight envelope is a plot of various curves representing the limits of the aircraft's true airspeed and altitude. Generally, the top-left ...
A flight envelope diagram showing V S (Stall speed at 1G), V C (Corner/Maneuvering speed) and V D (Dive speed) Vg diagram. Note the 1g stall speed, and the Maneuvering Speed (Corner Speed) for both positive and negative g. The maximum “never-exceed” placard dive speeds are determined for smooth air only.
The absolute ceiling and service ceiling diagram of an aircraft. With respect to aircraft performance, a ceiling is the maximum density altitude an aircraft can reach under a set of conditions, as determined by its flight envelope.
An aircraft is streamlined from nose to tail to reduce drag making it advantageous to keep the sideslip angle near zero, though an aircraft may be deliberately "sideslipped" to increase drag and descent rate during landing, to keep aircraft heading same as runway heading during cross-wind landings and during flight with asymmetric power.
Basic fighter maneuvers (BFM) are actions that a fighter aircraft makes during air combat maneuvering, historically known as dogfighting.The development of BFM began with the first fighter aircraft, during World War I, then continued with each following war, adapting to the changing weapons and technologies.
The British Aircraft Corporation TSR-2 is a cancelled Cold War strike and reconnaissance aircraft developed by the ... According to the Flight Envelope diagram, ...
China Airlines Flight 006 damaged by going outside its flight envelope to gain control after a drop of 3,000 m in 20 seconds. Flight envelope protection is a human machine interface extension of an aircraft's control system that prevents the pilot of an aircraft from making control commands that would force the aircraft to exceed its structural and aerodynamic operating limits.
