So have i misinterpreted what boeing wants then? I read it that in the cruise boeing want you to maintain a thrust and take whatever speed you're given.
Boeing wants you to set a target thrust to get a target speed for cruise.
That target speed for all phases is 280 and .76 (or .73 for the classic). The AFM makes that clear. So does the PH. The FCOM takes away the emphasis on the target cruise speed and just gives you the technique.
Can you think of a reason why climbing or descending through FL340 in turbulence you should be at M.76/280 but while cruising at FL340 you should be at another speed?
