Good Points = And...
While not overtly stated, the bottom line remains: whatever system you fly, know it inside-out... Know what the gonculators will do, why and how to get them out of the way when necessary. Current reading suggests that triple pilots have learned these methods and '87 boys and girls are still working through the process. The three week (or however long) upgrade course simply will NOT - cannot teach everything that you need to know.
This time, perfect stick and rudder just won't make it: one must know the systems well and yes, the function and effect of EVERY switch on knob, including how it may interact with other systems.
Most 787 sales remain foreign, yet basic training is done in English. Regardless of ESL levels, the pilot's brain simply does not capture everything presented. IMO, it will take another 5+years to build a cadre of truly, fully qualified pilots for the '87 series. The majority of the necessary learning comes through DOING (Flying in this case), not reading or watching or even SIM time. It is a very different beast, one that can be commanded, but damn sure not in 3-4 weeks time. It will happen; some will become experts, but we just are not there yet.
