What is the visibility requirement for Special VFR operations during the day?

For Special VFR operations during the day, the visibility requirement is indeed 1500 meters. This specific visibility requirement is set to ensure that pilots can maintain visual reference to the ground and sufficiently see and avoid obstacles and other aircraft. The rationale behind setting this visibility threshold is to provide a safe operating environment in conditions that may not meet standard VFR flight rules but still allow for a certain level of flexibility.

In contrast, visibility requirements for regular VFR operations typically exceed this minimum, reinforcing the importance of clear visibility for safe navigation and obstacle avoidance. Special VFR is designed for situations where pilots need to operate within controlled airspaces or under specific limitations, which is why a lower visibility standard is permitted, yet it remains crucial that visibility is adequate for safety.
