V/B

[Guest autothrottle]

Hello,I've just notice that:737-800 & 900 series have a less important V/B on the DESC page that 737-600 & 700 series.Moreover, with the 8 and 900 series it's rare that "drag required" appear on the FMC.Is that similar with the real 737NG ?Thanks in advance.

More details :During a descent, the V/B with the 737-800-900 is about 2.5 while the V/B with the 737-600-700 is about 3.5Is that the same thing with the real plane ?
