No, but if they discovered a discrepancy, they could turn the whole system off for the rest of the flight. Although this is not ideal, and a tri-voting system would be better, turning the system off...

I noticed this comment a few times in the Seattle newspaper. But on those FDR traces of the Ethiopian accident, it clearly shows that full back elevator was being applied (at the very end), and the...

The original 737 hardware was the 286 processor, and they were still using it in the NG.
If the same is true for the Max, the number of Silicon Valley techies who understand this antiquated system...

LowObservable.

You forget that number 3. is also widespread in smaller airlines and some third world airlines. That is why most aircraft have multiple redundancies, and don’t have safety-critical...

Think about it. These are the technical pilots who liaise with the FAA and write the manuals, and they seem to have no idea how MCAS works. As you say, they are conflating MCAS with Speed Trim, and...

In other words, a MCAS failure was being deliberately obscured as a trim runaway - when it was not. A trim runaway does not start and stop. A trim runaway is not triggered by a single faulty AofA...

A basic tenet of aviation, is you are not supposed to (allowed to) use the trimmer as a primary flight control. It is only there to remove stick loads, after a manoeuvre has been completed. You can...

Actual terms and conditions

The Daily Mail is reporting that Ryan pilots get £175k per annum, and are demanding £375k per annum.

Another reason for all modern engines being a long way forward, is so that ‘fly-away’ blades do not go straight through the wing. (JT8D blades were much smaller, and the diameter if the engine was...

Interesting two graphs.
And of course the 21 second interval in vertical speed cycles, equates very nicely with 10 secs of MCAS trim input and 10 sects of manual trim resetting. Prima face evidence...
