Shock wave. The sound barrier or sonic barrier is the large increase in aerodynamic drag and other undesirable effects experienced by an aircraft or other object when it approaches the speed of sound. When aircraft first approached the speed of sound, these effects were seen as constituting a barrier, making faster speeds very difficult or ...
Aircraft noise pollution refers to noise produced by aircraft in flight that has been associated with several negative stress-mediated health effects, from sleep disorders to cardiovascular disorders. [1][2][3] Governments have enacted extensive controls that apply to aircraft designers, manufacturers, and operators, resulting in improved ...

Wake turbulence is a type of clear-air turbulence. In the case of wake turbulence created by the wings of a heavy aircraft, the rotating vortex-pair lingers for a significant amount of time after the passage of the aircraft, sometimes more than a minute. One of these rotating vortices can seriously upset or even invert a smaller aircraft that ...
