At such speeds, shock waves form in the air passing over the wings, drastically increasing the drag due to drag divergence, causing Mach buffet, or drastically changing the center of pressure, resulting in a nose-down moment called "mach tuck". The aircraft Mach number at which these effects appear is known as its critical Mach number, or M ...
In these transonic speed ranges, compressibility causes a change in the density of the air around an airplane. During flight, a wing produces lift by accelerating the airflow over the upper surface. This accelerated air can, and does, reach supersonic speeds, even though the airplane itself may be flying at a subsonic airspeed (Mach number < 1.0
Aircraft upset is an unacceptable condition, in aircraft operations, in which the aircraft flight attitude or airspeed is outside the normally intended limits. This may result in the loss of control (LOC) of the aircraft, and sometimes the total loss of the aircraft itself. [1]
The wait is over, buffet lovers. Farmer’s Buffet − located at 206 W. Camp St. in East Peoria − is open for business. The building had once operated as Grand Village Buffet but was most ...
It is caused by a sudden impulse of load increasing. It is a random forced vibration. Generally it affects the tail unit of the aircraft structure due to air flow downstream of the wing.

Musician, loved for his beach bum soft rock, died in a hospice
A pilot and a sailor, Buffett wrote songs about his plane being shot at by Jamaican police ("Jamaica Mistaica"), getting lost in the Sahara Desert ("Buffet Hotel") and smugglers he had known ...
Mach tuck occurred at speeds above Mach 0.65; [3] the air flow over the wing center section became transonic, causing a loss of lift. The resultant change in downwash at the tail caused a nose-down pitching moment and the dive to steepen (Mach tuck). The aircraft was very stable in this condition [3] making recovery from the dive very difficult.
