> The airspeed unreliable checklist requires advancing throttles to the appropriate setting for the current stage of the flight regime, which was climb out.
It's basic airmanship to know that if you are not in climb attitude, that high power is going to overspeed in anything slick. Combine that with "overspeed" alerts and you should maybe realize it's time to pull the power back.
> They turned it back on in the hopes that the electronic trim could overpower the aerodynamic load where they could not, they did not realize that closing the circuit would give at most five seconds before MCAS dove again. Also, by this point, they were out of checklist.
They turned it back on, clicked the trim switch briefly, and then left it alone, despite knowing they were way out of trim. Can you explain why this makes sense? Why turn it on and not get back to nominal trim?
Also, they were still climbing at Vmmo (or overspeed). It would have always been an option to climb a bit...
