In the last few months, I’ve had two similar incidences in which I was flying an A321 out of KLAX on the DOTSS2 departure. At around the time I crossed DOTSS as I was approaching my planned cruising altitude of about FL350, I started gradually losing airspeed and the aircraft swayed uncontrollably from left to right, and then up and down. The autopilot throttle could not keep up with the turbulence and dropping airspeed, and eventually the aircraft stalled. The first time this happened, the aircraft was below MTOW but above MLW. Since I figured that the incident may have been due to the aircraft being somewhat overweight, I was sure the second time that I was below both MTOW and MLW before departing from KLAX, but alas, it happened again. I realize that this problem obviously has a lot to do with wind, but I’ve flown that departure countless times and have only ever had a problem with the A321. What can I do to prevent this from happening in the future with this and other aircraft?
Thanks so much,
