What is required for an aircraft to take off from a control zone during special VFR?

For an aircraft to take off from a control zone during special VFR conditions, a two-way radio is essential. This requirement ensures that the pilot can communicate with air traffic control (ATC) while operating in controlled airspace, thus facilitating safe and efficient operations in potentially low visibility scenarios.

In a special VFR situation, pilots are permitted to operate in weather conditions that do not meet the standard Visual Flight Rules (VFR) minima, provided they maintain visual reference to the ground and do not enter instrument meteorological conditions (IMC). The two-way radio allows the pilot to receive necessary instructions and clearances from ATC, helping to mitigate the risks associated with lower visibility.

Other options, while important in various contexts, do not specifically address the requirements for conducting a takeoff under special VFR in a control zone. A flight plan is typically advisable but is not mandatory for special VFR. An airworthiness certificate ensures the aircraft is fit for operation, but it does not pertain specifically to the special VFR conditions. Lastly, while a licensed pilot must be onboard to operate the aircraft legally, the focus of the question is specifically on the unique requirements associated with special VFR operations in a control zone.
