What type of airspace requires 2-way radio communications prior to entry?

1. Class A

2. Class G

3. Class D

4. Class B

The correct answer is: Class D

Class D airspace is designated as airspace that requires pilots to establish two-way radio communication with the controlling air traffic facility prior to entering the airspace. This requirement is in place to ensure safe and efficient operations within controlled airspace, where air traffic is more congested and coordination between pilots and air traffic controllers is essential. When approaching Class D airspace, pilots must listen to the ATIS (Automatic Terminal Information Service) broadcast, which provides important information such as current weather, available runways, and any notices affecting operations. After obtaining this information, pilots will then contact the appropriate air traffic control facility to receive clearance and ensure that their entry into the airspace is coordinated. Other airspace classes have different communication requirements. For instance, while Class A and Class B airspace also require two-way communication, Class G airspace is uncontrolled and does not mandate any communication before entering. Thus, understanding the specific communication protocols for different classes of airspace is crucial for pilots to maintain safety during their flights.
