The Federal Aviation Administration (FAA) Flight Standardization Board (FSB) has tentatively found the updated Maneuvering Characteristics Augmentation System (MCAS) on the B737 MAX aircraft to be "operationally suitable".

The FSB, which is responsible for setting pilot training requirements, included the MCAS as one of the special emphasis areas during training.

"MCAS ground training must address system description, functionality, associated failure conditions, and flight crew alerting. These items must be included in initial, upgrade, transition, differences, and recurrent training," the FSB report said.

The report is open for comments until the end of April and covers the B737-7, the B737-8, and the B737-8-200 types, which were deemed "functionally equivalent" types.

While the FSB report is a step towards the reactivation of the B737 MAX aircraft, multiple regulators around the world indicated that they will want to perform their own tests of the updated software, independently of the FAA.
