The US manufacturer has a lot of reassuring to do when it comes to digital flyingA Southwest Airlines Boeing Co. 737 aircraft. So how could a Boeing computer programme tasked only with preventing aerodynamic stalls — a much more limited task than the A320’s early brain — be at the centre of an investigation into two deadly crashes of the cutting-edge Boeing 737 Max? By contrast, the versions of the Boeing 737 currently flying have physical links between their control columns and the surfaces. But because the 737 does not fly-by-wire, software improvements to allow for new engines on the same airframe had to be created from scratch, not revised. As investigators sift through evidence, Boeing is racing to fix the MCAS, and it is expected to announce a software fix this week.
