So next will be automatic wind sheer manoeuvre. So after AF447 A350 has automatic unreliable speed change over, it has automatic EMER DES, auto TCAS. In first two they blindly believed in ATHR and allowed their speed to drop badly and in Islamabad the capt took for granted heading mode and dialling in NAV mode till Hdg went past 180, then on sudden realization pulled heading, the aircraft turned shorter way into the hills. This is what happened A320 Bangalore, B777 SFO, A321 in Islamabad. This is a case of automation dependency which develops in time and degrades the scan and people get caught. That's what you do in EMER DES, TCAS or GPWS or even turning to avoid weather. Normal principle is when you dial something on FCU you confirm appropriate aircraft reaction. The AP had not tripped but was disconnected and they forgot.

The capt who was PM suffered from automation dependency. Then what wil happen in Hudson case, unreliable speed or in sever upset is unthinkable. Sudden wind sheer warning in normal weather may cause a surprise but causing cognitive incapacitation is not very digestible. There are procedural lapses and psychologists are having a field day. This is not limited to Airbus products, there have been plenty of examples of mishandled go arounds in Boeings. In the report it is labelled as cognitive incapacitation. The airline I am with has been using the sim to develop strategies to overcome startle effect and to look at the physical reaction a person experiences when faced with an unexpected event. Eventually the the Captain said "everyone silent" which seemed to restore order. In this case there was a third pilot who was talking to the F/O. Startle effect and poorly handled go arounds are nothing new and unless there is a clear statement of who is control then you have two pilots trying to recover the situation. After a brief skim of the AvHerad article it looks like the F/O was still trying to control things after the Captain took over. Cockpit gradient can be influenced by a carry over of military culture. Not necessarily a good combination for a commercial airliner. In that company there is a high number of former Air Force and Navy pilots.
