Seattle Times staff reporters
In the middle of Boeing 737 cockpits, sitting between the pilot seats, are
two toggle switches that can immediately shut off power to the systems that
control the angle of the plane’s horizontal tail.
Those switches are critical in the event a malfunction causes movements that
the pilots don’t want. And Boeing sees the toggles as a vital backstop to
a new safety system on the 737 MAX – the Maneuvering Characteristics
Augmentation System (MCAS) – which is suspected of repeatedly moving the
horizontal tails on the Lion Air and Ethiopian Airlines flights that crashed
and killed a total of 346 people.
But as Boeing was transitioning from its 737 NG model to the 737 MAX, the
company altered the labeling and the purpose of those two switches. The
functionality of the switches became more restrictive on the MAX than on
previous models, closing out an option that could conceivably have helped
the pilots in the Ethiopian Airlines flight regain control. | g********0

测试。这么隐藏后，很多功能就慢慢被放弃了。
