I found a circular that says that you can only exceed 250kts below 10000ft if your minimum speed for the flight configuration is above 250kts. The circular tells pilots to inform departure control "minimum speed 270kts". Well, to me that must mean minimum clean speed, and if it does, than it also means that you dont have to remain with flaps to keep 250kts. And if that is the case, I dont see why it would be different for the 200kts limitation that also specifies "for the flight configuration".
So, on departure, we also have to maintain 200kts? If you say the limitation is because of birds, than the answer must be yes...?
