I think it is NECESSARY in training so as to avoid simple mistakes under test pressure.
For such a small investment in time and effort its a very very worthwhile skill to have.
411A's ridiculous assertion that FMC training would be more valuable is laughable.
Which FMC? Which software update? Operated to which SOP's?
A better candidate for Initial Sim and Line Training I cannot think of than the FMC!
