I am trying to be the devil's advocate so the community understands how technology fares against them. Soux city was a great feat, Hudson, gimli is nothing compared with it. However for Sioux city problem a software to use thrust/weight and asymmetry is possible and was being developed but due low probability of repeat it wasn't pursued. In Hudson, gimli case providing data base of gliding range without power and an additional electric hydraulics for AP can be even better managed. All credit to Sullenberger for doing what he did but if you critically analyse except the decision to ditch rest of the things human error under pressure was evident. He wasn't maintaining proper speed and when his speed dropped 19kts below Vapp it triggered alpha protection which prevented stall but also hampered proper flare and aircraft impacted heavily. So automated Airbus protection did help. Computers can handle data base of similar or possible accidents and quickly provide the lone pilot with correct solutions, and with better automation execute itself. As against this Mangalore accident in 2010 (not the only one) despite good aircraft and perfect weather due to poor Piloting158 people lost their lives. These things will be taken in consideration.
