Two-way radio communication must be established with ATC prior to entering which class of airspace?

1. Class B

2. Class C

3. Class D

4. Class A

The correct answer is: Class C

Two-way radio communication with Air Traffic Control (ATC) is required before entering Class C airspace. Class C airspace is typically found around busy airports and is designed to manage the flow of air traffic in areas with significant commercial and general aviation traffic. Establishing communication ensures that pilots operating in Class C airspace can receive instructions, advisories, and traffic information from ATC, which enhances overall safety and efficiency. In Class C airspace, ATC is responsible for separating aircraft and providing essential services to both IFR (Instrument Flight Rules) and VFR (Visual Flight Rules) flights. By requiring two-way communication, ATC can confirm that pilots are aware of their presence in the airspace and can provide necessary instructions to ensure safe operations. While other classes of airspace—like Class A and Class B—also require communication with ATC, the question specifically asks about prior communication, and Class C uniquely has regulations requiring this before entry. Class D requires communication but only when the aircraft is approaching or within the airspace, while Class A is primarily for IFR operations where communication is inherently maintained.
