Buffet limit aircraft
WebNov 26, 2014 · At high speed his limit is high speed buffet and ultimately wing drops or other Mach effects on the aircraft. The two speeds the pilot uses for flying the aircraft does not help his navigation, for that he needs the True Air Speed, TAS. It describes the aircraft’s speed through the air and when including the effect of winds, the ground speed ... Webknown as transonic shock buffet, acts as a limiting factor in aircraft performance. The reduced frequency of shock oscillation is typically on the order of the low-frequency structural modes, resulting in an aircraft that is susceptible to limit cycle oscillations (LCOs), and as a conse-quence, diminished handling quality and fatigue life.
