Boeing to add an additional warning light in 737 MAX jets in case of sensors failure

An additional warning light will become standard equipment in Boeing 737MAX.

The light will let pilots know when two sensors that gauge the plane’s angle of attack, meaning whether it is pointed up or down, are in disagreement.

The sensors work in tandem with the plane’s automatic system for lowering the plane’s nose if it senses it is popping up.

The warning light has been available as an option. Now Boeing will make it standard, the Associated Press and other news outlets reported, based on anonymous sources.

The alarm will tell pilots if two “angle of attack” sensors — which indicate the angle of a plane’s nose — disagree, a sign that one is not working.
