Yes, unless you operating below a Class B shelf in the United States your "standard" speed restriction is 250 knots below 10,000 ft. MSL.
I find the Class B shelf speed restriction somewhat problematic in areas where shelfs are quite high. For example, in Atlanta (KATL) part of the class B airspace starts at 10,000 feet and ends at 12,500 feet (I think). That means a business jet going into a satellite airport must slow down to 200 knots while ATL TRACON vectors us around the side of the airspace. Seems silly to slow to 200 knots at 9,000 feet.
What airspace is used in metropolitian areas in Europe? Class C?
