I'm pretty confident that the recorder will be just fine. If there is a silver lining to an accident with a brand new aircraft, it's that it has brand new recorders - and the new solid state...

Those numbers are for "Sea Level Static" thrust. Thrust in-flight is different. On large turbofan engines, the net thrust 'lapses' (decreases) with forward speed - the higher the bypass ratio, the...

Ah, no they are not... The maximum engine ratings on the Max are very similar to the corresponding models of the NG. The larger models are allowed more thrust because the increased leverage of the...

I suspect Boeing cleared the press release with the NTSC prior to release (remember, Boeing is party to the investigation so there is ongoing communications). And it really doesn't say anything new -...

Quagmire, when Boeing became a delegated authority, they implemented robust protections against "Undo Pressure" - arguably much better than before delegation. When I was a DER, if I felt I was being...

No, not a rubber stamp. The FAA FAR and EASA CS regulations are for the most part the same, but there are some significant differences. When a new TC or ATC is applied for, there is a meeting...

Silver, not really disagreeing with anything you wrote. I doubt you'd get much argument that MCAS needs a serious re-think.
Sadly, this wouldn't be the first time that the 'fix' for an accident...

There are several failures that can cause a stab trim runaway - and not all are solved by turning the system 'OFF". In addition to welded switch contacts, the motor can fail in such a way that you...
