The aerospace giant said in a statement a warning light related to two sensors meant to determine a plane’s position in the sky was turned off in most 737 Max planes. Neither Lion Air nor Ethiopian Airlines planes had purchased the upgrade, per The New York Times. Boeing said once it determined in 2017 that the warning light software wasn’t standard, a team of company-employed experts found it “did not adversely impact airplane safety or operation. Boeing said Sunday it was working to implement the warning light feature as standard before the 737 Max returns to service. Boeing software called the Maneuvering Characteristics Augmentation System (MCAS), meant to keep the 737 Max planes from stalling in mid-air, has also been under review.
