I’ve had 2 “interesting” encounters with wake turbulence in 737’s – both approaching in the terminal area. One encounter was along the track of the vortices and caused about a 30 degree bank with a significant amount of opposite aileron along with some rudder input. The other was 90 degrees to the vortices – and caused 2 very abrupt bumps in otherwise calm air. Neither of these prompted a change in draws afterwards but they definitely caught my attention. Of course the 737 doesn’t have the mass of an Airbus 300 but given other structural problems I could see how the event could start the ball rolling.
