Officer Kite, MPLs at the moment are at least flying with Captains from the previous era. 6 years down the line from now we will have MPLs promoted to Captain, MPL Co Pilot with a Captain from the MPL route. System reliability and automation is the reasons safety records are so good.
And in normal operations when nothing goes wrong these automation operators are fine, but when you get that 0.001% occasion when it goes wrong, I would like people up front who have done more than 50 hours of flying on something that isn't an Airbus.
In the 70s there were a number of notable accidents due to MCC issues, hence the prevalence and emphasis on CRM in training in following decades. However in the last 6 years the incidents and accidents are now getting attributed to handling issues.
Yes low hour pilots from Cadet schemes are not new, but prior to JAA, these Cadets were select candidates fully sponsored; not just anyone who could put up 100,000k up front for training and pass some token selection test.
RAF pilots from World War 2, they followed a training route of increasing difficulty, Tiger Moth, Harvard- Avro Anso - Lancaster, all these stages of training built and developed skill, not something really comparable to DA40 to DA42 to Airbus.
