I think this is one of those situations where you may not be able to assign fault to any one set of people. Remember that everyone here has the clear advantage of knowing what went wrong and how, the people who designed this may not have

The trim adjustments by MCAS can be disabled by setting the two stabilizer trim cutout switches[1] to cut-out. The recognition that trim is being automatically adjusted outside of their ability to control the aircraft and how to correct i

The pilots could have been trained to understand all the control surfaces on the airplane and how to identify their configuration. From what is reported about the Lion Air crash it sounds like the pilots may not have sorted out what the sta

The new engines are not that much more powerful (NG: 120kN, MAX: 130kN max thrus), its that they are physically larger. The issue (nose up tendencies at high power settings) was an issue with the 737 Next Generation as well, its just more p

Yes, but the 737 has been around since 1967, which is what the person your replying to was talking about. Going between the 737 NG and the 737 Max would not be a big change even if they were different type ratings, but going from say some t

They had serious problems with the autopilot, which also disables MCAS.

From what I have read, the NG series had the habit of pitching up under go-around conditions and this system exists because Boeing expected that issue to be more prevalent on the Max and also to try and solve it. So its not a new thing on t

When you have limited space to show some information, sometimes the space it takes up needs to be reduced.

Boeing was doing what the airlines wanted, which is provide a new more efficient airplane that requires minimal training for existing 737 pilots to fly, much like the A320neo. Airlines are the ones who schedule the pilots and their traini

IIRC, The flight recorders are tested by Boeing before delivery to the customer. Planes undergo several weeks to a month of tests by Boeing before delivery and sometimes undergo even more testing by the customer after delivery. Most like

In that case it was a really old aircraft that stalled in the way that MCAS is designed to prevent. One thing to note is that this flight is very similar to the previous Ethiopian crash.

The idea that we should parade the heads of the people responsible for this around on a pike is a very emotional reaction. Of course, these will be the people who will be less likely to make any mistakes with this sort of system again, s

I'm really getting tired of hearing "Boeing cut corners" every time this comes up. Boeing is more a customer-driven company than most other industries. They would want to design a new plane, they in-fact were proposing a

Because its quite possible that grounding the planes would result in more fatalities. People may drive or get shuffled onto older, less safe aircraft.

Existing connections using the config when they were initiated is intended to prevent inconsistencies when changes are being made, these inconsistencies could lead to connections being dropped en mass after a config change.

The pilots are required to, by memory, know when this particular situation is happening and how to disable the system. The checklist is the runaway trim checklist, to turn the system off the pilot flips switches next to the trim-wheel, wh

POODLE was also an issue with other ADC vendors, I think it links back to where those ADC vendors got their initial TLS code, how the industry went about implementing it, etc.

Speaking about the theatrical and rock concert industry... In some ways the cases are standardized around being a quarter, third or half the width of a semi trailer inside width in some dimensions. So once its in a case its usually okay.

I think one of the things we loose when we transitioned from newspapers to reading news online is the drive to condense information and curate what is reported for such a broad audience. I distinctly remember how my grandfathers, both of th

Many embedded processors these days allow you to disable the JTAG/SWD debugging port. So once that is disabled it becomes quite a bit harder to read data from any of the on chip memory using external devices.

So, if an employee was not at work, not expected to be at work, do they need to apply for and get PTO to avoid getting calls in that off time? It seems pretty clear that if the employer expects response in a certain time frame, the employee
