Most countries, including the US, grounded Boeing’s 737 Max 8 aircraft following a second deadly crash two weeks ago. The company has scrambled to address concerns over the plane’s automated flight control system and now says it has a fix ready.

The 737 Max software was recently updated to include a featured called the Maneuvering Characteristics Augmentation System (MCAS), which was supposed to make the planes safer by automatically adjusting the jet’s “angle of attack” if the nose tipped too high.

MCAS will now get data from both of the plane’s angle of attack sensors instead of just one. If those sensors are 5.5 degrees or more apart, MCAS will shut itself off and not attempt to nudge the nose of the aircraft down.
