FAA Ground School Practice Test

When flying in the airspace underlying Class B airspace, what is the maximum speed authorized?

1. 180 knots

2. 220 knots

3. 250 knots

4. 200 knots

The correct answer is: 200 knots

When flying in the airspace underlying Class B airspace, the maximum speed authorized is 200 knots. This regulation is in place to ensure safety and organization around busy airports that are typically found in Class B airspace. Class B airspace is often located near major airports, where traffic is more congested, and maintaining a lower speed helps reduce the risk of wake turbulence and facilitates easier navigation for pilots operating in the vicinity. Additionally, flying at a reduced speed allows for better response time in case of unexpected events, such as the need to avoid other aircraft or to comply with air traffic control instructions. The specific speed limit of 200 knots helps establish a buffer zone for aircraft operating at lower altitudes, ensuring that they remain clear of faster-moving traffic in the higher classes of airspace above. While higher speeds may be permissible in other categories of airspace, the regulation for the area below Class B is specifically designed to enhance safety and manage air traffic effectively.
