It’s a catch 22 situation, if Pilots fly manually in the aircraft then there will be incidents. If Pilots use the automation then there will be fewer incidents, until they have to fly manually when there will be more incidents because they are out of practice.
In the past simulators were used to practice for flying aircraft, now aircraft are used to practice for check rides in simulators. Typically a pilot goes for 3-6 months between Sim sessions. After relying on the automation for an extended period he has a base check coming up in a few days and decides to do an approach with auto thrust and flight directors off. Then the fun starts with speed and flight path excursions as the engines power up and down, unstabilised approach/ go around/ hard landing is the result.
Safety department sees a trend and bans manual flying, examiners see a lower standard on base checks due to lack of currency.
A suitable solution would be regular manual flying sessions in a simulator every month or so but that costs money.
