Which equipment is needed for operation within Class C airspace?

To operate within Class C airspace, a pilot must have two key pieces of equipment: two-way radio communications and a transponder that is capable of transmitting a 4096-code. Class C airspace requires effective communication between the pilot and air traffic control, necessitating the use of a two-way radio. This allows for the necessary coordination and instructions from the air traffic personnel managing the airspace.

In addition, a Mode C transponder is required in Class C airspace. The 4096-code transponder provides air traffic controllers with the ability to see an aircraft's altitude and location on their radar, improving situational awareness and safety within areas that are often busy with both commercial and private flights.

Thus, having both two-way radio communication equipment and a 4096-code transponder ensures that pilots can communicate effectively with air traffic control while also providing the required information for safe navigation and separation from other aircraft in the controlled airspace.
