What is an aircraft envelope?
In aerodynamics, the flight envelope, service envelope, or performance envelope of an aircraft refers to the capabilities of a design in terms of airspeed and load factor or altitude. The term is somewhat loosely applied, and can also refer to other measurements such as manoeuvrability.
What is an aircraft safety envelope?
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.

The gust envelope is four lines overlaid on the flight envelope, usually the plus/minus of maximum gust at design cruising speed (Vc) and half maximum gust at maximum speed (Vd) as required by the certifying authority.
What is envelope function?
In physics and engineering, the envelope function of a rapidly varying signal is a smooth curve outlining its extremes in amplitude. The figure illustrates a sine wave varying between an upper and a lower envelope. The envelope function may be a function of time, or of space, or indeed of any variable.
What is gust in aviation?
A gust is briefer than a squall and usually lasts 20 seconds or less. Air turbulence around an obstacle causes gusts; they occur frequently over buildings and irregular ground and are less frequent over water. The term gust also denotes a sudden change in wind speed relative to a flying aircraft.
How is gust load calculated?
Calculate the tail load, the gust load factor, and the forward inertia force. Take ρo = 1.223 kg/m3. that is, The total load on the tail is then 16,480 – 10,813 = 5,667 N (upward).
