What is the required visibility for VFR flight in Class G airspace?

For VFR (Visual Flight Rules) flight in Class G airspace, the required visibility is indeed 5 kilometers. This standard is established to ensure that pilots can maintain a clear visual reference to the ground and surrounding terrain, which is essential for safe navigation and obstacle avoidance while flying.

In Class G airspace, which typically exists at lower altitudes and is less congested, the 5-kilometer visibility requirement balances the need for safety with the flexibility to operate under visual conditions. Pilots must be able to see far enough to navigate effectively and to detect any other aircraft, ensuring a safe flying environment.

Other options such as 3 kilometers, 8 kilometers, and 10 kilometers do not reflect the established regulations for Class G airspace under VFR. The distinctions in visibility requirements are determined by different airspace classes and specific conditions, such as time of day or type of operation, but for Class G, the 5-kilometer requirement is the standard recognized to enhance flight safety.
