So far then it looks like an unreliable airspeed problem which wasn't handled correctly and resulted in tragedy. Even back in the 1970s D.P. Davies was complaining in "Handling the Big Jets" about pilots who had forgotten how to fly due to automation, it's far worse these days as progression onto airliners is more rapid and the level of automatics is more advanced.
Today's generation of aviators are taught to operate autopilots virtually from the start and have never developed basic skills on steam driven aircraft. It's routine to engage the A/P a few seconds after lift off and only disengage it a couple of minutes before touchdown. Setting an attitude and a power setting and making adjustments to achieve the required flight path was a basic and essential skill for an earlier generation of pilots but today's crop can largely get away without the old skills, until something goes wrong. It's a sad fact that many airline pilots today are only able to do their jobs because of the level of automation on modern aircraft, they couldn't cope with an aircraft that had to be FLOWN rather than operated.
