I didn’t even know there was an MSNBC special report.
I am, however, deeply involved in the design and testing of aircraft control software, and have been for several decades.
Article reeks of islamb bo fovvia of this particle of divinity who shines out like a god.
A god of death, blood, and human sacrifice, just like fricking Allah.
That is why the internet is the sweet spot to have the real truth said about Islam.
We did. We learned can't "discriminate" against Muslims because it would be Islamophobic. In fact, our law enforcement and military can't even identify Islamic terrorists as "Islamic Terrorists".
We must all remain at high risk so we don't offend The Religion Of Peace.
Every time I fly somewhere I am struck by how the airport staff in all positions seems to be disproportionately high in people who appear to be of Arabic or other middle-eastern origin or ethnicity. I assume these are sleepers.
Anybody else observe that?
I apologize then; you are more of an expert on this subject than I am. I am not completely convinced that aircraft control software enhances safety. But there is a huge amount of evidence that the software is more dependable and less prone to error than pilots in the form of billions of miles of commercial airline miles flown with an almost incomprehensibly stellar safety record. And there is an equally convincing amount of evidence that pilots of general aviation aircraft, ultralight aircraft, and hang gliders such as myself have a pretty bad safety record in the form of accident reports.
Me! I wish I had a Staples button to settle the issue decisively.
...the software is more dependable and less prone to error than pilots in the form of billions of miles of commercial airline miles flown with an almost incomprehensibly stellar safety record...
Historically, this has been true.
However, in the case of “MCAS”, based on the little information publicly available, it appears several profoundly bad decisions, violating long-standing principles, were made in its development.
I have been most interested in what the pilots that I know have said about it. And they did have some complaints, but the complaints were that the system behaved differently than what they were accustomed to. Boeing’s automatic stabilizer trim has worked the same way for around 40 years and none of them saw a good reason for the change in the way the system behaved. The flight characteristics of the system could have been changed to make up for the changes in the aerodynamics without altering the behavior of the way the stabilizer trim was used.
None of the pilots felt that the emergency procedures that they knew would not work if there was a malfunction. None of pilots that I know who have flown the 737 MAX have felt that it was an unsafe airplane. Sorry for the redundancy here, but almost all of them agreed that the software development on the new system was misguided because it changed the characteristics of a tried and true system unnecessarily and this contributed to the confusion that caused the pilots to lose control of their aircraft.
When the AOA vane that MCAS was using was working properly, MCAS probably also worked fine; it was when that single AOA vane went bad, probably indicating “full-scale high” that MCAS would drive the airplane into the ground.
That was a colossal human failure of the highest order.
It is hard to take you seriously when you make exaggerated statements. As an aviation control expert you should be well aware that “runaway trim” has been an issue from various causes since electric trim assist was first devised who knows how many decades ago. That is why there are cutout switches right next to the trim wheel of every airplane that I am aware of that has it. And this is true even for airplanes that don't have a computer “helping” the pilots.
A sticky solenoid, a short circuit, a bad switch or sensor can all cause the problem. Are solenoids that malfunction, wires that have bad connections, or sensors that have bad sending units colossal human failures as well? All the nonsense from self appointed non-flier experts with no historical perspective is the reason I stopped commenting on this issue months ago. Thanks for reminding me.
This is exactly what I have been thinking the past couple of days.
