WSJ - FAA, Boeing Have Tussled Over Pilot Training for 737 MAX Software Fix

​​​​​​...Boeing has been advocating comparatively limited training, the people said, consisting of new, written materials aviators would receive explaining operation of the automated stall-prevention feature—and how to respond if it malfunctions.

But the FAA, they said, increasingly is pushing for more extensive training, consisting of pilots engaging in self-guided instruction on a laptop computer; the computer-based instruction would include more details and require more time to complete than reading a handout.

The second option gained support, according to one of the people involved in the discussions, after ground-simulator sessions sponsored by the FAA showed computer-based training would be required to ensure average pilots know what the changes mean and how to respond...
The editors obviously missed the point that MCAS isn't a "stall-prevention feature".

​​​​​​...The most important element of the pending software revisions is that in the future, MCAS is expected to use feeds from a pair of sensors measuring the angle of the plane’s nose—instead of the current reliance on a single sensor. The change was prompted by preliminary findings in the Lion Air crash probe, showing that incorrect data fed into a flight-control computer from a single sensor precipitated the deadly chain of events.

The pending software fix also will limit the number of times in succession the MCAS system can push down a plane’s nose and lengthen the interval between such automated commands, according to the person involved in the discussions.

Some Boeing officials were informed about the training decision earlier this week, this person said, but other government and industry officials briefed on the matter said they weren’t aware a formal determination had been made...
