A321 fasten seat belt sign noice
Hi I'm new so if this is the wrong forum area excuse me.
Yesterday I was on a flight from Faro to Birmingham. We took off as normal and and it was all smooth until about 10000ft when we hit some chop which continued for about 30 minutes and was what I would call heavy turbulence. It smoothed out and the captain turned the seat belt sign off but instead of the hearing dull seat belt sign noise there were 3 beeps like an alarm was going off. At this point everyone in the cabin started looking at each other including the air hostesses. I was sat in row 7a and the crew had just started handing out drinks and were at about row 3 when the 3 beeps came over the pa. One of the air hostesses immiediatley stopped serving drinks and headed towards the flightdeck to see what had just happend. She had a look of worry and surprise on her face which didnt help me much and i'm a frequent flyer.
Just wondering if any of new guys have experianced the same thing and if you know what may have happend?
thanks
Harry
