Aviation has always been about flying.
Whilst type of personality is one part of the equation. The bottom line is to be EFFECTIVE and this comes from a solid amount of operational experience. This experience allows a crew member to be effective and thus contribute to a safe flying operation. Experience cannot be replicated in a bloody simulator.
Always treat with a dose of scepticism someone purporting to represent the "new and modern" way as it is often the case, they lack the experience to know the value of experience
