What visibility requirement is adjusted in Class G airspace under Part 135?

In Class G airspace, the visibility requirement specifically changes based on the altitude of the flight and prevailing weather conditions. Under Part 135 operations, when the ceiling is below 1,000 feet, the visibility requirement is increased to 2 statute miles. This adjustment is made to ensure a greater margin of safety for operations in lower visibility conditions, thereby assisting pilots in maintaining adequate visual reference for navigation and avoiding potential conflicts with terrain and other aircraft.

This standard is particularly important for Part 135 operators, who often have more stringent requirements than general aviation, especially in terms of safety protocols in varied weather conditions. The increased visibility requirement is a measure designed to enhance safety during operations conducted in more challenging environmental conditions.
