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

To operate within Class C airspace, a pilot must have specific radio equipment that facilitates communication and provides essential information regarding the aircraft’s altitude.

The correct answer indicates that the minimum required equipment includes two-way radio communications equipment, a Mode C transponder, and an encoding altimeter. Two-way radio communications are necessary to communicate with air traffic control (ATC) while entering and flying within Class C airspace, which typically includes a busy airspace environment around airports.

A Mode C transponder is crucial as it enables ATC to track the aircraft's position and altitude in real-time. The encoding altimeter provides the aircraft's altitude to ATC, which is vital for maintaining safe separation between aircraft in controlled airspace.

While other options may include some components relevant to airspace operations, they do not fulfill all the requirements set forth by regulations regarding Class C airspace. For instance, a single-band radio or only having a transponder does not ensure effective communication or altitude reporting, which are essential components for safe operations in this environment. Additionally, GPS is beneficial but not a requirement for Class C operations. Thus, the answer focusing on the combination of two-way communication, a Mode C transponder, and an encoding altimeter accurately reflects the
