What minimum radio equipment is required for operation within Class C airspace?

• A. Two way radio communications equipment, a 4096 code transponder, and an encoding altimeter.
• B. Only a VOR receiver.
• C. GPS with WAAS.
• D. A radar altimeter and traffic avoidance system (TAS)

Answer: (A)

Class C requires two-way radio communications with ATC and altitude reporting capability to keep you identified and separated on radar. Before entering and while operating in Class C, you must establish and maintain two-way communications with ATC on the assigned frequency. In addition, your aircraft must be equipped with a transponder that can report altitude (Mode C), typically indicated by a 4096-code transponder, and an encoding altimeter that provides your altitude data to ATC through the transponder. This combination lets ATC see both who you are and how high you are, which is essential for safe sequencing and separation in this busy airspace. Other options fail to meet these critical requirements because they do not provide the necessary two-way communications or altitude-encoding capability.
