Capt claret! You are spot on with your reply!
On a 777 the turb speed is m.82 or 280 whichever is less, if you are heavy it is
To be 15 kts above the yellow band, this causes sometimes confusion !??! ???
The crossover usually is between FL 340 and 350 then 280 becomes M.82
Amazingly during climb pilots observe this speeds quite strict,during descent
They tend to fly faster and do not care to much about turbulence, - strange, but
That's how it is!
