Boeing Co is set to make two new software updates to the computer used in controlling the flight of 737 MAX, said the company on Tuesday, another effort by the airplane maker to get approval of regulators to airborne its planes again which were grounded after facing two deadly crashes with a gap of five months.
One issue involves a possibility of leading the plane to disengage itself from the autopilot mode during final approach, while the other issue relates to hypothetical faults in the microprocessor of flight control system which have possibility of leading the pilot to lose control of the plane, a situation termed as runaway stabilizer, confirmed the company, adding that the new updates will serve the purpose of addressing both the issues.
As Boeing is continuously working on the 737 MAX’s automated flight control system, the Federal Aviation Administration (FAA) is in contact with the company, but compliance of all certification standards should be demonstrated by the manufacturer, the agency said on Tuesday.
Boeing is the largest U.S planemaking company, but after the two disastrous incidents, it has been rigorously working to fix the software issues in the 737 MAX that was grounded since March 2019 and resulted in halting production of ther same by the company in January.
Boeing is expecting resuming the flights of grounded planes around mid of this year, a forecast recently made by the company and it is not seeing any impact of the new software issues as those are not related to MCAS, an important anti-software system found to be malfunctioned in both fatal incidents. Boeing is putting its efforts to protect MCAS by updating the system software.
Boeing also said that it has not found any new software issue in the flight of 737 MAX and flight deck warnings and alerts are already working properly by sending appropriate alerts to the crew.
