What is required before a VFR aircraft can enter Class C airspace?

Before a VFR aircraft can enter Class C airspace, establishing two-way radio communication with the Air Traffic Control (ATC) that manages that airspace is mandatory. This requirement ensures that the pilot can receive instructions and updates from ATC while operating within the controlled airspace. Communication includes acknowledging the ATC's instructions, which confirms that the pilot has received and understands the necessary information to maintain safe operations alongside other aircraft.

While clearance or authorization may seem relevant, the specific requirement is based on the need for effective communication with ATC. Establishing this two-way communication allows ATC to manage air traffic within Class C airspace effectively and enhances safety by ensuring that pilots are aware of other traffic and any potential hazards. The establishment of two-way radio contact is indicative of the pilot’s compliance with airspace entry requirements, making it crucial for the operation of VFR flights in these environments.
