An aeroplane flying above the Critical Mach No. will usually experience

  • an oscillation in pitch
  • a nose up pitch
  • a nose down pitch

Explanation from PART66Online

Above the critical Mach number the centre of pressure moves rearward as shock waves develop, placing more lift behind the centre of gravity and producing a nose-down pitch known as tuck-under. The result is a steady nose-down change of trim rather than a nose-up pitch or an oscillation.

Ain't the oscillation a more logical answer?
