Irrespective of what part of the world you are talking about, the quality and style of the basic training at flight school sows the seeds for the embryonic pilot.
Whilst instrument flying is a major part in what is taught prior to multi-crew flying, being comfortable “turning an aircraft onto its back” is part of the development needed to expand the SA capability of student pilots.
Limiting the basic non IF flying training to steep turns and stalling, together with the EASA 5 hour UPRT package, to “tick the box” is not the solution to prevent this type of tragic accident in the future.
Whilst EASA recognise the need to improve SA, it must be only a temporary measure until a more robust training syllabus is adopted.
And yes, it will cost more, but compare that to the price of this style of accident, not only in momentary terms for the beancounters, but the human suffering which inevitably occurs as well.
