What are the operational procedures for a flight in Class C airspace?

In Class C airspace, the primary requirement for pilots is to establish two-way radio communication with Air Traffic Control (ATC) before entering the airspace. This means that a pilot must contact the ATC facility responsible for the airspace and receive clearance to enter. This requirement is in place to ensure safety and maintain an organized flow of air traffic, allowing ATC to provide traffic advisories, separation, and instructions to pilots operating in that airspace.

To operate safely within Class C airspace, the emphasis on communication helps prevent conflicts and enhances situational awareness for both pilots and ATC. The establishment of two-way communication also often entails responsiveness from the pilot to ATC instructions, ensuring ongoing coordination during the flight operation.

The other options do not align with the specific requirements set for Class C airspace. For instance, not needing to communicate with ATC prior to entry contradicts the fundamental operational guidelines for this class of airspace. Similarly, filing a flight plan is not a mandatory requirement for Class C operations, and autonomous operations are not permitted due to the need for ATC oversight in managing the busy airspace.
