WebApr 7, 2024 · Mach buffet (vibrate) is “high-speed” buffet. It occurs when too fast in an airspeed or too high in an AOA near the Mmo. Usually, airflow separation due to shock wave as well as wave drag produces a turbulent wake behind the wing, which causes the tail surface to buffet (vibrate).

When an aircraft slows to below its stall speed, it is unable to generate enough lift in order to cancel out the forces that act on the aircraft (such as weight and centripetal force). This will cause the aircraft to drop in altitude. The drop in altitude may cause the pilot to increase the angle of attack by pulling back on the stick, because normally increasing the angle of attack puts the aircraft in a climb. However, when the wing exceeds its critical angle of attack, an increase in an… Webif you fly any faster, you will exceed the maximum Mach number ( M m o) of your aircraft, resulting in high speed buffet, vibrations and possible loss of control. if you fly any slower, the maximum lift that the wing can provide will be insufficient to maintain altitude.
