757 Max

Interesting program last night about the 737 Max – in which it’s computer drove 2 planes into the ground on receiving wrong info from a poor sensor. Repeated efforts to correct from the pilots were overridden by the computer :-(( [Edit] Interesting that the search engine excepted 757 – anyway of changing the title? |

Do you like watching fourth time repeats? But well done for posting something other than participation sport. |

Surprising what you can see in repeats :-) |

Watch the rest of the series. The epsisodes are really fascinating. |

More worrying, the lack of redundancy in the sensors, the push to try to make an aircraft that behaves in a fundamentally different way seem to be “the same thing” to make it more attractive to potential purchasers (if it’s not different, pilots don’t need training/recertification). It’s a culture that means if I ever fly anywhere, I’ll specifically ask if it’s a Boeing, because…it shouldn’t have taken two. |

It evently has two sensors one each side. By which means can you test which sensor is giving the correct result? |

The big change to this system is that the pilots now know about this new software and can deal with it. (If only by switching it off) |

As both a former aerospace software engineer and a pilot, it the lack of diligence by Boeing is doubly shocking. This was once a fine engineering lead company, but after the reverse take over by McDonnell Douglas, it has been ruled by bean counters, with a terrible culture of cost and corner cutting directly responsible for hundreds of deaths. The company did everything possible to hide the massive changes to the flight characteristics of the MAX compared to previous generations of 737s, from the pilots who would be flying it. All to avoid any extra training costs, in which they were aided and abetted by both the customer airlines and the FAA as regulator, who outsourced much of the certification to the manufacturer itself. The last of the great Boeing aircraft, the 747, has just rolled off the production line, leaving the troubled 787 and the fatally compromised 737 MAX. It would be too much to hope for a complete change in culture before the 777X production line starts up. |

Our company did some subcontract work for Boeing back in 1999-2001 (on Nimrod update). Their QA was pretty thorough at the time. |
