What is the maximum indicated airspeed aircraft can fly in Class B airspace after departing the airport, at 1,700 feet AGL?

In Class B airspace, specific speed restrictions are in place to ensure safety and order, especially given the high volume of air traffic typically present in these areas. The applicable regulation states that pilots are generally prohibited from exceeding a maximum indicated airspeed of 250 knots when below 10,000 feet MSL (Mean Sea Level).

When an aircraft departs from an airport located in Class B airspace, the 1,700 feet AGL measurement typically translates to a height that is well above the surface but still under the 10,000 feet MSL threshold, assuming that the airport elevation is not excessively high. At 1,700 feet AGL, this still falls within the regulated environment of Class B airspace.

The regulation's stipulation allows aircraft to fly at a maximum speed of 250 knots while remaining compliant with Class B airspace rules. Therefore, since 250 knots aligns with the specifications for operating within the limits of this airspace above ground level, this answer is correct.
