The following: * Changes to the trim system electrical wiring to prevent possible shorts (none have been reported so far). * Changes to the flight laws in the computers to limit MCAS activation authority (how far it moves), limit activation to a single activation, require agreement between AoA sensors and other fixes. * Changes to the manual to outline MCAS system, interaction with other automatic trim systems, normal and non-normal (emergency) procedures. * Changes to baseline training to include more trim system troubleshooting, MCAS system theory and troubleshooting, AoA sensor indications, etc. * Changes in advanced training program recommendations for airlines.
