For a special VFR flight in Class E airspace, what is the required visibility?

For a special VFR (SVFR) flight in Class E airspace, the required visibility is 1 statute mile (SM). This requirement is important for maintaining a certain level of safety during operations in controlled airspace.

SVFR operations are typically conducted when weather conditions below standard VFR minimums exist, allowing pilots to operate in controlled airspace while still adhering to specific visibility requirements. The 1 SM visibility requirement ensures that pilots have enough visual reference to maintain safe flight and separation from other aircraft.

If the visibility were lower than this standard, it would pose potential risks to flight safety, such as difficulty in seeing other aircraft or maintaining orientation with the ground. Hence, the National Airspace System has established this minimum visibility to balance safety and the flexibility needed for pilots to operate under special circumstances.

When conducting a special VFR flight, pilots must also stay clear of clouds and maintain visual contact with the ground or water to ensure safe navigation.
