Auto correct? I don't know what that means. From this morning's online edition of AW&ST:

Not everyone is expressing dismay over the way Boeing handled MCAS information. The United Airlines Master Executive Council (MEC) says that while the MCAS may be new, its function is not, and pilots already knew how to manage an MCAS-linked problem.

“Despite the omission of the MCAS description in the initial 737 MAX differences training, United pilots are properly trained in handling an MCAS malfunction,” Capt. Bob Sisk, chairman of the MEC’s safety committee, wrote to members. “[W]hen working properly, the system helps us avoid stalls. If it faults or activates due to a related system fault (like an AOA sensor), it presents itself to pilots as runaway stabilizer trim . . . something we can recover from using existing QRH procedures with the flip of the cutout switches.”

The runaway trim procedure (how the pilot reacts) remains the same from the Classic, to the NG, to the MAX.

Either control yoke trim switch would overide the MCAS, or either trim wheel on the sides of the pedestal. With the systems in cutout, the pilot would have full authority over the stab trim with the manual wheels alone.

I'll wait for a preliminary report before expressing an opinion.
