What is the maximum cruising altitude for VFR operations without ATC clearance in Class C airspace?

The correct choice reflects the regulations governing VFR operations in Class C airspace, which is primarily set to ensure safety and order within areas of increased aircraft traffic. Specifically, VFR (Visual Flight Rules) pilots without ATC (Air Traffic Control) clearance must remain below 4,000 feet above the ground level to operate safely in Class C airspace. This altitude limit helps minimize the risk of conflicts with higher flying aircraft that are typically operating under IFR (Instrument Flight Rules), as Class C airspace is designed to manage the safe flow of both VFR and IFR traffic.

In larger Class C airspace areas, the vertical limits create structured layers for airspace use, and the 4,000-foot maximum for VFR pilots helps to provide a buffer for ATC to manage those who are actively flying under their guidance, maintaining safer operational boundaries for all.

Understanding this altitude restriction is crucial for pilots to ensure compliance with regulations and to maintain safety within controlled airspace.
