Boeing's new passenger aircraft has crashed twice within the space of a few months, raising a number of safety questions. So far, the 737 has been the backbone of many fleets globally.In other words, the plane is BUILT TO CRASH, and only the MAX performance of software keeps it from crashing. I don't know anything about planes but I know a LOT about software. I know that you CAN'T COUNT ON SOFTWARE for life-critical tasks. You always need a manual override or a human check on results.
For two years now, the Anglo-German travel company TUI has been making preparations for the arrival of Boeing's 737 MAX flagship plane. The first plane was due to be moved to Germany from Seattle this week. But now a massive debate about the safety of this aircraft is in full swing following the crash of a brand-new 737 MAX in Ethiopia on Sunday.
It's the second crash involving that particular model, following the Lion Air crash of October 2018, in which 189 people were killed. The model has now come under intense scrutiny, so how does it differ from other 737 models, the best-sold aircraft in the world?
It had developed a large number of modernized and improved versions over the years, but some 10 years ago, the company realized it had to come up with something different after rival European rival Airbus gained the upper hand in terms of global sales with its A320neo. Boeing found itself under enormous pressure to keep up. And that was its problem. Unlike the A320, which was able to accommodate larger engines under its wings, the Boeing 737 didn't lend itself easily to the same thing, as its wings were a lot closer to the ground.
Boeing was thus forced to make compromises and overhaul its old 737 model instead of developing an entirely new one. To make the LEAP engines fit under the wings, the nose landing gear had to be extended to ensure enough distance to the ground. On top of that, the new engines had to be mounted further apart from the outboard wing assembly, and that changed the plane's aerodynamics. This in turn causes the plane to lift its nose, which triggers a compressor stall in the worst case scenario, which in turn can lead to a crash.
To counter this possible effect, Boeing uses a special technology called Maneuvering Characteristics Augmentation System (MCAS), which automatically lowers the nose to head off a compressor stall.
