Unfortunately, these sorts of occurrences highlight systemic problems within the industry. And I am, of course, speaking in general terms.
The regulator sets the minimum requirement. It is then up to the operator to set the standard, above and beyond this level, which is relevant to their respective operation.
Compliance with the regulations is only the starting point to a safe operation.
It is seems far easier to focus on the pilot these days rather than the architecture that they have to work within. Why should a pilot have to train at home on flight sim when a second/supervisory pilot can be introduced on a dead sector to allow time under the hood? It doesnt even cost any more money! If we want to be serious about having a first rate industry then we need to be proactive about moving away from the lowest common denominator.
