Boeing says did not intentionally deactivate 737 MAX safety feature

Boeing said Monday it did not "intentionally or otherwise" deactivate a safety alert for its angle-of-attack sensors on its 737 MAX aircraft, responding to reports the planemaker failed to tell Southwest and the USaviation regulator that the safety feature was deactivated before recent crashes. "The disagree alert was tied or linked into the angle of attack indicator, which is an optional feature on the MAX. Unless an airline opted for the angle of attack indicator, the disagree alert was not operable," Boeing said. It said the disagree alert is not necessary for the safe operation of the airplane. The company said following software modifications all new MAX aircraft will have an activated and operable disagree alert and an optional angle of attack indicator, while current MAX airplanes will have the ability to activate the disagree alert.<br/>
