[...] With this amount of sink, decreasing speed will be difficult.
For that reason real aircraft often level out at 10k ft. They leave the power at idle and reduce to 250kts. Then they increase the sink rate again. And sometimes they also use the speed brakes (spoilers). For the A320 family its recommended by Airbus to only extend the spoilers to about 50% while in cruise... mosty for passenger comfort I think
