I am still learning this plane and reading and watching vids. I am not using Air Traffic Control yet. When I program the FMC it looks good ,and use LNAV and Vnav but when I am descending it starts with a very fast decent at over 3000 ft per minute but then levels off to about 2000 after it has gone down about 4000 ft. My problem is that when it is decending it ignores the speeds in the FMC and if I try to reduce the speed on A/T it ignores as it is trying to get to the next altitude and keeps up the speed. This is especially true when crossing the 10k feet 250 knots.
I hope I am explaining right, I am not having too much trouble taking off, just when taking off and what point to most people turn on vnav, is it around 1000 ft ?
