If an aeroplane accelerates above the critical Mach number, the first high Mach number characteristic it will usually experience is: 11. a a nose-up pitch or "Shock Stall" b.a violent and sustained oscillation in pitch (porpoising). c Dutch roll and/or spiral instability. da nose-down pitching moment (Mach, or high speed tuck). 12. High speed buffet is caused by: a the shock waves striking the tail. bthe high speed airflow striking the leading edge of the wing. c wing flutter caused by the interaction of the bottom and top surface shock waves d the airflow being detached by the shock wave and the turbulent flow striking the tail.
