Hi Randy - thanks for getting back to me.
To be honest I don't know what got into that state. The speed was 190 (set by me) with flaps, so I'm not sure how it decided to go into an alpha floor state - at other times those speeds have not been an issue.
After all of that, I had to restart the auto throttle, but it always acted in the same way.
I gave in with the flight, but I will try again.
I've been having a lot of problems using these Airbuses lately - but on this occasion the a319. I you look at the cockpit settings , I can'the see a problem with any of my settings, but the system has reacted real bad. Firstly, it was set to 190kts, with flaps set to one, but all of a sudden my aircraft was over 300kts and I was getting an alarm (it was also set to A/FLOOR) ! I had done nothing to get that - the autopilot was set to 190kts and had flats set to 1, why did it react like (I'm sorry you can hardly hear my voice in the video, but its not that appropriate if you keep an eye on the systems.
