What is a restriction for flying under Special VFR (SVFR)?

Flying under Special VFR (SVFR) has specific requirements designed to ensure safety under reduced visibility conditions. One of the primary restrictions is that the pilot must maintain a visibility of at least one statute mile and remain clear of clouds. This requirement emphasizes the importance of visual reference to navigate safely and avoid obstacles.

Having a radio on board is also essential for communication with air traffic control while operating under SVFR. This ensures that pilots can receive instructions and traffic advisories, enhancing situational awareness and safety in controlled airspace. Therefore, the necessity to have the radio operational while maintaining appropriate visibility is critical.

The other restrictions mentioned, such as ground visibility being less than 1 statute mile or flying only during daylight hours, do not correctly align with the standard requirements for operating under SVFR. In fact, SVFR can be requested when the visibility is less than standard visual flight rules, but it cannot be lower than one statute mile. Thus, while maintaining communication and proper visibility are key elements of flying under SVFR, it also gives flexibility to operate in weather conditions that would typically restrict other VFR operations.
