Re: Boeing 737MAX Grounding, General Discussion Thread, Q3 2020

As sgrow787 may say, either MCAS was broken or it was not. I think we can all agree it was broken, no? Surely them working on a fix tells us they knew it was. Depends on what you mean by "MCAS". If you include AOA sensor validation and cleanup within the MCAS subsystem, then yes, it was b...

Re: Boeing 737MAX Grounding, General Discussion Thread, Q2 2020

Whether it wants a 3rd AOA probe, or doesn’t, is not a question of safe or unsafe. Safe or unsafe is not an on/off switch. The question is whether the regulators feel that the plane is sufficiently safe with only two AOA probes, or not. That is a question of opinion. Generally, if you ask people whe...

From the A320 onwards, I believe all the manufacturers have chosen FBW for their new designs. So, clea...
