@qdaniele97 what’s even worse was not only was there no checks or redundancy but there were absolutely no checks and balances to the nose down input overrides MCAS was giving the plane. It didn’t take into account airspeed, altitude, rate of descent, contradictory pilot inputs or the number of times the MCAS system had overridden pilot inputs. It took absolutely no account of what the plane was doing, where it was and what the pilots were trying to do. It was the most stupid and dangerous piece of software ever to be put into an aeroplane, and it came about because Boeing sacked their avionics software engineers with over 30 years existence and outsourced all their software to an Indian offshore IT company with no experience in aerospace software engineering at all

@kirilmihaylov1934 that’s exactly true, what on earth makes you deny the truth? 😂

mcas should have been implemented with checks and balances such as: Monitoring altitude, rate of descent, and airspeed for deviations from expected values. Verifying pilot inputs align with safe parameters. Predicting flight paths to detect deviations from the intended profile. Comparing parameters to established limits. Setting autonomous behavior limits to prevent excessive interventions. Providing clear indications of system activity to pilots.

@djpalindrome bingo. This exactly

@DeltaAssaultGaming they couldn’t make it fly by wire. The whole point of Mcas was to replicate the flying of traditional 737s by taking into account the difference in handling the bigger engines meant so they didn’t have to retrain pilots. If they’d made it fly by wire, it would have meant retraining pilots and this is the number one thing Boeing wanted to avoid. The seconds thing they wanted to avoid was paying Market rates for avionics software engineers, and when you pay peanuts you get monkeys

@Drizzit57 2 out of 4 blew up after rich it was scrapped, and the inbuilt rockets weren’t really reusable without massive refurbishment which resulted in a complete rebuild. It cost far more than the Russian program on which the USA relied for over 20 years after the space shuttle was cancelled.

@mikoto7693 I won’t be flying on a max, or any new Boeing, for a long time. Their culture is to sacrifice safety for cost, and then hide any dangers to the public as much as they can. This culture hasn’t been changed, and will continue. There have been numerous problems with all Boeing’s made in the NC plant for starters. I gave no doubts there will be another crash and Boing will do their best to hide the real reasons behind it from the public.
