It isn't about notions like efficiency, cost-control or shortened training footprints, it's about pilots being familiar and therefore comfortable in their machine, no matter what it costs or how long it extends the training footprint. And it doesn't take tens of thousands of hours in a career, or weeks added onto the normal training footprint to achieve this comfort - it takes work, mainly on the part of the pilot, but also on the part of the airline in providing a supportive, comprehending management approach to foster this level of comfort.
Well said PJ, training to confidence is what it should be..
Unfortunately the bean counters (think reduced training time) & the regulators think testing testing is the way to go, but then they will not be in the smoking hole and can always go and get another job.
