Which statement is true regarding Class C airspace?

1. Requires no pilot requirement

2. Requires two-way radio communications prior to entry

3. Does not require a transponder

4. Allows uncontrolled aircraft operations

The correct answer is: Requires two-way radio communications prior to entry

Class C airspace is a type of controlled airspace that requires pilots to establish two-way radio communication with air traffic control before entering. This requirement is in place to maintain safety and efficiency by ensuring that aircraft operating in or near this airspace are in contact with air traffic controllers. This communication helps coordinate the movements of aircraft and reduces the chance of mid-air collisions, especially in busy airspace where there might be a significant number of operations happening simultaneously. Establishing two-way communication is essential for situational awareness for both the pilots and air traffic controllers, making it a critical aspect of operating within Class C airspace. This is why the statement about requiring two-way radio communications prior to entry is true. Pilots must receive an acknowledgment from ATC before entering, confirming that they are clear to do so, thereby enhancing overall air traffic management in that region. The other options do not accurately reflect the requirements of Class C airspace. For instance, there are specific pilot requirements for operating in this airspace, like having a valid flight certificate. Additionally, transponders are indeed required in Class C airspace to maintain radar contact with ATC. Lastly, all operations within Class C airspace must be under controlled conditions, meaning uncontrolled aircraft operations are
