When the AP drops off unexpectedly and rolls the plane into a 45 degree bank, reading the FMA and trying to figure out the FD is going to leave a pilot perplexed and confused all the way to the crash site.
It doesn't happen in Airbus. Aircraft stays where it is you just have look at the parameters and set them right. Don't bring in Boeing situations. In airbus people have dis connected AP and crashed or caused incidents. Not reading FMAs have landed people in trouble in Airbus. Look! let's understand straight if one makes heavy weather of raw data in airbus there's no way he is going to do it in a Boeing or even a non FBW Airbus for that matter. You don't manoeuvre Airbus you just set it where you want it.
Alternate law just keep wings level which you have do in a Boeing all the time.
