I read in a recent magazine article that MMO on the 787 is .92.


If true that's impressive, and the same as the 747. It seems, with a planned cruise Mach of .85 and the ability to increase that if needed Boeing continues to see the benefit of speed.


Anyone know if this MMO figure is accurate, and, out of curiosity what the VMO is ?

Resurrecting this thread, because I had the same questions, and the answer seems harder to find than usual.

Any 787 pilots able to shed some light?

FYI, the TCDS can be located via the faa.gov website. Search for TCDS and it is fairly easy to navigate from there.

For the 787, this eventually links to

T00021SE_Rev_28.pdf (faa.gov) (https://rgl.faa.gov/Regulatory_and_Guidance_Library/rgMakeModel.nsf/0/77307d23dbd22592862582500069226d/$FILE/T00021SE_Rev_28.pdf)

It is useful for folks to know how to find the sheets as they contain a whole bunch of important certification data for whatever aircraft in which you may have an interest.
