The FAA states "The height–velocity diagram or H/V curve is a graph charting the safe/unsafe flight profiles relevant to a specific helicopter. As operation outside the safe area of the chart can be fatal in the event of a power or transmission failure it is sometimes referred to as the dead man's curve ."
Its comprises helicopter aerodynamics, stability, control, structural dynamics, vibration, and aeroelastic and aeromechanical stability. [1] By studying the forces in helicopter flight, improved helicopter designs can be made, though due to the scale and speed of the dynamics, physical testing is non-trivial and expensive.
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 measurements such as maneuverability.

The AS350 is a single engine helicopter, powered either by a Lycoming LTS101 or Turbomeca Arriel powerplant (for twin-engined variants, see Eurocopter AS355), that drives a three-blade main rotor, which is furnished with a Starflex rotor head. The type is known for its high-altitude performance and has seen use by operators in such environments ...
Aircraft performance refers to the ability of airplanes and helicopters to accomplish certain useful things. [1] It is an important consideration when designing and testing aircraft, to ensure the aircraft can be operated in an efficient and economic manner. [ 2 ]
Disk loading of a hovering helicopter is the ratio of its weight to the total main rotor disk area. It is determined by dividing the total helicopter weight by the rotor disk area, which is the area swept by the blades of a rotor.
