Sounds hairy. Do the Dreamliners regularly fly at 41? I remember riding on one of the original 727’s on a demo flight in 1964, and they took it up to 40, but throughout the service of that model, through the stretch and QC’s, they rarely flew over 36 or 38. Control surfaces start to get mighty thin, mighty fast, way up past the sweet spot. Starts taking a lot more fuel, too.
There’s only two kinds of plastic........
Pilots no longer fly, they are flight systems managers. A “seat of the pants” pilot would have overridden the changes and flown the plane.
And while all this was happening, what was the crew doing; playing canasta? Or were they maybe playing a friendly game of grab-ass with the flight attendants?!
What is the cruise speed of a Boeing 787?
Answer:
Mach 0.89 Which is also 677 MPH
Actually it’s cruise speed was originally supposed to be Mach 0.89 as the 7E7, as the 787 it is Mach 0.85. Basically 5% faster then the 767 and most airliners, and 20% less fuel burn. Other interesting points are it is composite, which gives some great benefits for passengers.
It’s way easier on your ears as it can pressurize 60% higher, much better when you have a cold or sensitive ear canals.
One of the other stress’s of today’s jet traveler, all the air is humidified so much less dehydration. Other metal aircraft don’t do this.
Turbulence is minimized by a state of the art turbulence mitigation system.

Look for the union label on those generators.
I took the Boeing factory tour in Everett, WA last spring. I believe the guide said the client picks either a GE or Rolls Royce engine that’s fitted to the Boeing Dreamliner. The SC facility is for troubleshooting.
Well, with the United Airlines on time performance around 70%, the passengers should have been grateful for an early landing!
The aircraft exceeded maximum operating speed while on autopilot that’s why they descended and diverted.
Normal cruise for the 787 is M85, MAXIMUM cruise speed is M89.
