Pot calling the kettle black innit?

I agree with Soji development has become fickle instead of giving a finished product that is stable and reliable its bits and pieces at a time but this is exciting news for android oh my GOSH AC3 ysflight on my phone I am in heaven THANKS SOJI!!!!!!!!!

Boeing 737 MAX-800

Some topics came to my attention.
  • The crashed Boeing 737 Max aircrafts of Lion Air and Ehiopean Air had one of the two AOA sensors failed.
One of the TWO?  Sounded to me the MCAS system has such an important part of the auto-pilot.  Even Boeing dropped its long tradition of Yoke Jerk functionality and gave priority to the MCAS over the human pilot.  And, it was taking only two inputs?  The first aircraft that had an operational digital fly-by-wire computer control was F-16.  F-16 had 3 control computers, each of which were taking airspeed information from an independent Pitot tube.  If one of the three Pitot tubes failed physically or iced up, the computer takes votes and go with democracy.  Having three separate systems improved the reliability of F-16.

If there are only two inputs, it is good for a human pilot because a human pilot can identify which one failed.  We are trained to cross-check instruments.  From the computer point of view, having two input doesn't give redundancy.  When one fails, it doesn't know which to trust.  Still Boeing might have made an decision that the AOA sensor is unlikely to fail.  I can only guess.  But, I don't know if having only two AOA sensors was a good idea.  It's a very un-Boeing-like case.
  • Control Software Issue
I am seriously worried about the wrong trend of programming. Too many programmers are thinking they can just release an incomplete software and then release updates to fix errors.  It is utterly wrong.  Even for-consumer products it is wrong. Users are not specimen. The trend can be contagious. If this wrong mentality is contaminating the control-software developers in the aircraft design field, I hope it is not the case, but it is scary. Someone needs to stop this wrong trend.
“Someone needs to stop this wrong trend”, — Lets fix YSFlight firstly! P.S.: @CaptainYS, please, open sources of YSFlight - give us a chance to fix YSFlight!

I can't roll my eyes hard enough at the irony of his statement.

I had two paragraphs about my thoughts on the MAX crashes and even Soji's attitude but then I realized it's not going to matter because he won't give a shit.

I agree with you on that statement

Except in this case one of the entities isn't even coming up with updates to fix the errors present.
