I think this has been posted before, but this is all we were told about MCAS on the NG to Max B1 conversion. Obviously this was before the accidents. The course was 11 classroom days and 3 days practical training.
Maneuvering Characteristic Augmentation System
The maneuvering characteristic augmentation system (MCAS) allows the stabilizer to move in the nose down direction when approaching high angles of attack at high speeds. This requires the stabilizer to move in the opposite direction in which the pilot is pulling the column for nose up pitch. The MCAS only operates at extreme high speed pitch up conditions that are outside the normal operating envelope.
Only the F/Os column cutout switch module is affected because it is the only module that interfaces with the FCCs
