What is the floor of Class B airspace at Dallas Executive (RBD)?

  1. At the surface

  2. 3,000 feet MSL

  3. 3,100 feet MSL

  4. 4,000 feet MSL

The correct answer is: 3,000 feet MSL

The floor of Class B airspace at Dallas Executive Airport (RBD) is indeed 3,000 feet MSL (Mean Sea Level). Class B airspace is established around major airports to manage air traffic and ensure the safety of both commercial and general aviation. The dimensions of Class B airspace typically extend from the surface upwards to a specified altitude, which can vary by location. In the case of Dallas Executive, the 3,000 feet MSL designation indicates that pilots operating in this airspace must maintain their aircraft at or above this altitude when entering the Class B airspace. This is crucial for ensuring that aircraft do not interfere with the operations at the airport, especially given that Class B airspace is heavily trafficked by commercial airliners. Understanding the specific altitudes that define different classes of airspace, including Class B, is essential for drone operators and pilots. It is important for them to be aware of the airspace in which they are flying and any restrictions that come with it, especially in a busy airspace environment like that surrounding Dallas Executive Airport.
