At the same time, the FAA's Flight Standardization Board (FSB) is preparing to issue new guidelines early next month for the training that all U.S. airline pilots must receive before flying the Max again. In April, the board issued a draft report after reviewing the initial MCAS fix Boeing had designed, which it "found to be operationally suitable." That report said full-flight simulator training, which is time-consuming and expensive for the airlines, is unnecessary ahead of clearing the plane to fly again. Instead, the board recommended only a short computer-based course and classroom instruction about the new software update. That report was shelved as Boeing's software update kept getting pushed further out. If the new training outline coming in September sticks to the previous recommendation that simulator training is not needed, that will boost the Max's return-to-service schedule, which is crucial to the airlines and to Boeing.
