To operate an aircraft in Class C airspace from a satellite airport without an operating control tower, which action must a pilot take?

The correct action for a pilot operating an aircraft in Class C airspace from a satellite airport without an operating control tower is to contact ATC as soon as practicable after takeoff. This is essential because Class C airspace requires two-way radio communication with air traffic control to ensure safe and efficient operations.

By contacting ATC soon after takeoff, the pilot establishes the necessary communication and can receive information regarding any traffic, procedures, or instructions that may be relevant while operating in or near the Class C airspace. This prompt communication also aids in integrating the satellite airport's operations with the traffic in the controlled airspace, ensuring that the pilot is complying with the regulations governing Class C airspace.

The requirement to contact ATC is particularly important since the airport does not have a control tower; the pilot must ensure that ATC is aware of their presence and intentions as they enter the airspace. Addressing this communication needs promptly contributes to the overall safety of the air traffic system.
