747-400 Buffet margin versus turbulence speed
Hello,
Looking at the AFM Cruise Maneuvering Capability graph I see that when flying at Mach 0.86 I have the highest aerodynamic ceiling however the turbulence penetration speed is 290-310 kts or M 0.82- M 0.84 whichever is lower.
I am puzzled since I would expect that M 0.86 would give me the biggest margin to buffet in case of turbulence?
Can anyone explain this to me?
