Wake turbulence?
On a recent flight into Manila from Xiamen on a China Southern A320 we hit what I would call heavy turbulence.
The approach was normal, then turbulence kicked in, just (to me the usual), then suddenly a jolt and perceived "drop" in altitude. Not a bump, a drop. Then very quickly a very big sound of rushing wind.
The engines seemed to throttle back, then after 30-40 seconds spooled up again and we carried on a normal approach.
Sorry for my lack of professional words here, I'm a regular flyer, but not a pilot. I'm trying to avoid all the school, hospital type references, but just wondering if this was wake turbulence from the aircraft in front?
My main reference is the sharp drop and the sound of rushing wind that I've never heard before in all my years of flying.
Thanks.
