I have a Question:
When I fly below 10‘000 feet the auto throttle accelerates the plane to 250 knots. But 230 knots is overspeed and the Auto Pilot automatically deactivates.
Is there a way to change the speed of the auto throttle?
How can I change the auto throttle speed?

Which plane are you flying? And in which situation does this occur?
If it's the A320 and just after takeoff then just retract the flaps to up.
In the A320 and A380 you can select a speed by pulling the airspeed knob out. Tap on the knob and pull the inner green circle down. To do that.
If you want to slow down to approach speed you can activate the approach phase in the A320 by pressing the PERF key on the MCDU and then select the key on the left side to activate the approach phase, press again to confirm. Then the autopilot will switch to the approach mode and instead will target the low speed.
In the B737, B747 and B777 you can should be able to either push the airspeed knob in or you can select a vertical mode like flight level change (FLC) to disable the VNAV that automatically controls the airspeed.
Keep in mind that when you use the autothrottle you should use the autopilot as well or at least force the autothrottle into the speed mode by selecting the vertical speed mode. It is a real hazard in the real world as well if you fly with autothrottle on and control the pitch manually. If the autothrottle is in CLB mode or DES mode then the engines will either go to full climb thrust or full idle and you have to control the airspeed with pitch, otherwise you overspeed or stall.

A320, if you are in flaps 1+F, the plane sets automatically flaps 1 at 212 kts, you can hear “took took”. After that it accelerates again and disables A/P because flaps 0 should have been set after S speed

Let’s say it’s also for beginners even though you have to set a bit the MCDU. The A320 keeps ~160 Kts until reaching 3000 ft above ground and then accelerates to 200 kts only. It’s easy, especially if there’s a u-turn just after takeoff.

Very nice channel!
