Supercritical airfoils feature four main benefits: they have a higher drag-divergence Mach number, [21] they develop shock waves farther aft than traditional airfoils, [22] they greatly reduce shock-induced boundary layer separation, and their geometry allows more efficient wing design (e.g., a thicker wing and/or reduced wing sweep, each of which may allow a lighter wing).
Location of France. France is a country whose territory consists of metropolitan France in western Europe, as well as several overseas regions and territories.A member of the Group of 7 (formerly G8) leading industrialised countries, as of 2014, it is ranked as the world's ninth-largest and the EU's second-largest economy by purchasing power parity.

English: Subsonic (1) and trans-sonic (2) airfoils at identical Mach number. A: Supersonic flow region . B: Shock wave . C: Area of stalled flow . On the trans-sonic (or supercritical) airfoil, the deceleration of the flow on the top surface, and the strength of the shockwave with which the flow returns to a subsonic regime, are reduced.

Transonic (or transsonic) flow is air flowing around an object at a speed that generates regions of both subsonic and supersonic airflow around that object. [1] The exact range of speeds depends on the object's critical Mach number, but transonic flow is seen at flight speeds close to the speed of sound (343 m/s at sea level), typically between Mach 0.8 and 1.2.
