Thanks for that graph.

I use the Cost Index to give me an approximation of VMR in the 737 but I am aware that it is taking account of the wind while in EcON mode so isn't exactly right.
1/From VMR can I work backwards to get VMD in IAS?
2/ Is VMD purely a function of weight and therefore the same IAS at FL380 or 2000ft for a given weight?
