From a very much edited report coming from the operator of the 320 damaged in BIO.
The A320 softaware prevented the crew from obtaining Max AOA when GA was called.
During the approach and below 150feet a very potent downdraft hit the aircraft. The F/O was PF at the time and pulled back on stick to arrest the rate of descent. At the same time the capt called for GA while pulling on sidestick without pressing priority button. The computers sensed that the sumation of both inputs would have placed de Aircraft beyond MAX AOA (Flaps 3) and responded with a zero increase of AOA. AOA at the time was 3degrees. Aircraft impacted on rwy at 3 degrees AOA main gear first with 4.8g´s and bounced. During the second impact nose gear collapsed.
