According to CAR 602.117, what is the minimum flight visibility for SVFR operations in a control zone for aircraft?

The minimum flight visibility requirement for Special Visual Flight Rules (SVFR) operations in a control zone, as outlined in CAR 602.117, is indeed 1 mile. This regulation is designed to ensure that pilots have sufficient visibility to navigate and operate safely within controlled airspace, particularly under conditions that might otherwise restrict standard visual flight operations.

The requirement aims to enhance safety by allowing pilots to maintain visual separation from terrain and other aircraft, while also enabling them to proceed with operations even in reduced visibility situations, as long as they can comply with this minimum. This visibility requirement is considered a balance between operational flexibility and safety, allowing pilots to conduct necessary flights while reducing potential risks associated with flying, such as collisions or controlled flight into terrain.

The other options present higher visibility requirements that do not apply to SVFR operations within a control zone as per the regulations. Therefore, understanding this specific regulation is critical for pilots conducting operations under SVFR conditions.
