Most of the airlines that I have worked for require at the minimum,
Pre-command assessment, absolutely.
Sim sessions, eight.
Loft, two.
Sectors (with check Captain), twenty to thirty.
And, altho many airlines now use level D simulators, most foreign aircarriers that I have worked for REQUIRE base checks in the aeroplane...and think this is a very good idea, nowithstanding the fact that it is expensive.
