Not bashing Airbus here........ It bashes its ownself quite well enough.
Reading the accident reports and explanations from "experienced" pilots, sounds like the old "Who's on first, what's on second" comedy routine of Abbott & Costello. This newer version is, unfortunately such a tragic one and seeming to repeat itself.
Cool sidestick controller whose position is hidden from other pilots, and if being manually manipulated by both pilots for whatever reason simultaneously, the A320 flight computers ADD the 2 control inputs together. Combined with thrust levers that don't move when FADEC makes thrust changes, major or minor.
Also it is alleged the 320 family will sometimes fully move the THS to full or nearly so, nose up, causing big difficulty,in getting the nose down - particularly when high thrust is occurring in low speed flight.
They said Titanic was unsinkable.
The 320, cant be stalled.
