Green Dot Speed above Managed Speed in Cruise

[gvert]

Hey everyone!

Just noticed in CRZ, that my Green Dot Speed is above the CI35 Managed Speed for my KBOS-KMEM flight. That's looking a bit odd.

FL340 (Opt FL329 - Max FL355) - CI 35 - GW: ~308.000lbs

Hi, 

Thanks for the post. We will look into this and check the calculation for GREEN DOT above 20,000ft.

Many thanks,

I noticed the plane has a tendency to dislike cost index lower than 60 especially if heavy as it would put the cruise speed below the green dot. Below cost index 60 the plane would generally like to put the speeds at mach 0.79 or lower. Currently am always using cost index 60-80 and the P.SPD and P.ALT would be alright .
