Improvements of Boeing 737

In recent days, the aeronautical giant Boeing unveiled the security improvements it plans to implement on 737 Max aircraft. Mike Sinnett, Vice President of the group, said that Boeing is working to “restore faith” in its brand and continue its commitment to safety and regain the confidence of passengers.

The presentation was attended by more than 200 pilots, technicians and regulators, where Sinnett affirms that the flight control system (MCAS) of the 737 Max “will provide additional layers of protection if the angle of attack sensors provide erroneous information”, and that Its updated software has been analyzed during “hundreds of hours”, including simulations and test flights.

In addition, the flight control system will receive data from two sensors of the “angle of attack” instead of one, and if there is a disagreement between them of more than 5.5 degrees when comparing them, it will not activate and will alert the pilots to through an indicator in the panel.

Boeing maintains that this indicator in the control panel of the flight is for the pilots to know when said sensors are in disagreement, also the training to the pilots will be reinforced so that they understand how the system works and how to deactivate it if there is a problem. Boeing maintains that the pilots “will always have the ability to cancel the MCAS and manually control the aircraft.”

The Federal Aviation Administration (FAA) must certify the software update and pilot training plan, after being approved by the US authorities, Boeing said he should send the update to his clients, who will take a few days to install it, test it and train its employees, while other regulators must give the green light before the aircraft fleet can operate again.

The good news for Boeing is that its shares rose 1.03% on Wall Street and contributed to briefly bring the Dow Jones group to positive territory.
