Hello,just taken off from EDDH. My Boeing 737-800 winglets is quite light indeed: ZFW 47.5 Kgs, only 30% of fuel. Well, I chose in CDU a Climb D-2 to reduce thrust due to aircraft's light weight and a cruise altitude of FL290.I was very impressed by the rocket climb performed, about 10 minutes to reach FL290! Trim corrected setup, SID flown manually before engage VNAV and being not able to reduce thrust (A/T also armed), I need to increace pitch attitude and a high V/S (even to 4-5000 ft/min). Below FL100 speed has been maximum at 290 kts! Very strange. I am a little bit surprised. What do you think about?Thanks bye.

Wow!!!!...ZFW of 47,5Kg???? It must be a plane made off paper. Yes the 737NG have very powerful climb rate, when nearly empty. There´s nothing wrong with that high V/S at allwhen very light. / Leffe
