The company is currently working on a software update in a system called Maneuvering Characteristics Augmentation Systems.
It is going to be quite a while before Boeing’s 737 Max takes off as it awaits Federal Aviation Administration approval. The company is still working on a software fix that keeps the jetliner grounded. On March 27, 2019, the company gathered hundreds of industry representatives at Seattle-area facilities to demonstrate the software fix. However, the company says it would need extra time to fix the problems that caused crashes in Indonesia and Ethiopia, killing a total of 346 people. Even after that, the FAA will conduct rigorous tests to make sure the problem has been addressed.
Currently, Boeing is working on a flight-control system which would require significant changes. The flight-control system was supposedly responsible for fatal crashes in Indonesia in October 2018 and Ethiopia in March 2019. Both mishaps had striking similarities: the flights experienced drastic speed fluctuations during ascent and both times pilots made futile attempts to return to the airport a few minutes before takeoff. Moreover, the agency said it had physical evidence and satellite data, showing similarities between two crashes. “Time is needed for additional work by Boeing as a result of the ongoing review of the 737 Max Flight Control System to ensure that Boeing has identified and appropriately addressed all pertinent issues,” said FFA.
Furthermore, FFA also insisted that the agency will not approve software installation, not until they are satisfied. Boeing is working on changes in Maneuvering Characteristics Augmentation Systems, known as MCAS. The company’s fix to the software problems appears to be flaws in the original system of MCAS. However, the company has defended that the change is to make it more robust. The investors wait for the update as the 737 Max still stays on the ground.
