Boeing is going to update the 737 MAX control software that's designed to fix a problem with the way the planes flies (BA)

Boeing 737 MAX

  • The Boeing
    737 MAX
    will receive updated flight control software in the
    coming weeks.
  • The software announcement comes four months after the
    crash Lion Air
    Flight JT610 and two days after the crash of Ethiopian
    Airlines
    Flight ET302. Both of which involved effectively brand
    new Boeing 737
    MAX eight airliners. 
  • The update will change the way the plane’s MCAS control
    software reacts to faulty sensor readings. 
  • Boeing expects the FAA to make the
    update mandatory. 

The Boeing 737 MAX will be receiving updated flight control
software, the airplane maker announced on Tuesday. The software
announcement comes four months after the crash Lion Air Flight
JT610 and two days after the crash of Ethiopian Airlines Flight
ET302. Both of which involved effectively brand new Boeing 737 MAX
8 airliners. 

In a statement, Boeing said:

“For the past several months and in the aftermath of Lion Air
Flight 610, Boeing has been developing a flight control software
enhancement for the 737 MAX, designed to make an already safe
aircraft even safer. This includes updates to the Maneuvering
Characteristics Augmentation System (MCAS) flight control law,
pilot displays, operation manuals, and crew training. The enhanced
flight control law incorporates angle of attack (AOA) inputs,
limits stabilizer trim commands in response to an erroneous angle
of attack reading, and provides a limit to the stabilizer command
in order to retain elevator authority.”

The Chicago-based aviation giant said that update will be
implemented across the 737 MAX fleet in the coming weeks.

Boeing expects the US Federal Aviation Administration to issue
an Airworthiness Directive “no later than” April to mandating the
updated software.

The company has not indicated it will make physical changes to
the aircraft that has been in service last spring. 

At the heart of the controversy surrounding the 737 MAX is MCAS
or the Maneuvering Characteristics Augmentation system. To fit the
MAX’s larger, more fuel-efficient engines, Boeing had to redesign
the way it mounts engines on the 737. This change disrupted the
plane’s center of gravity and caused the MAX to have a tendency to
tip its nose upward during flight, increasing the likelihood of a
stall. MCAS is designed to automatically counteract that tendency
and point the nose of the plane downward.

Unfortunately, initial reports from the Lion Air investigation
indicate that a faulty sensor reading may have triggered MCAS
shortly after the flight took off.
