I can understand why this would be priority for Airbus even without the incident of a flight losing altitude - recently read that a major philosophical difference between Airbus and Boeing is that Airbus prioritises the safety of the Aircraft through controls (hardware and software) where as Boeing believes a human should always be the final decision maker and be able to over ride any control. An Airbus rarely allows…
It’s an oversimplification to position them as opposites. Airbus uses higher level contol, more a flight path than a control surface movement. But pilots can revert to direct law and have full contol authority when required. Boeing aims for a more traditional control feel, you move control surfaces instead of commanding an outcome. But with layers of substantial augmentation on top of it, up to and including for exam…
In fact, the only way to get into direct law on a fully functional plane is to start pulling circuit breakers for the (redundant) flight computers and inertial reference units.
