MS FSX - takeoff from Paris CDG to Rome Fiume with B-737-800

[mistereezy]

Note sudden icing happening at 07:22. Speed gauges show 0 knots. The autothrottle immediately increased thrust to maximum. I had to disengage autothrottle and manually put about 70% of thrust, then switch on anti-ice mode. If you don't do it, overspeeding will end the flight pretty soon.
