What's the minimum visibility required for VFR flight at altitudes over 10,000 feet MSL?

For Visual Flight Rules (VFR) operations at altitudes above 10,000 feet Mean Sea Level (MSL), the minimum visibility requirement is indeed 5 statute miles. This standard is established to ensure that pilots maintain a sufficient visual reference to the ground and other aircraft while flying at higher altitudes.

At these altitudes, pilots are expected to navigate primarily by visual means, and the higher visibility requirement helps to reduce the risk of mid-air collisions and assists pilots in maintaining situational awareness. It's also important to note that the minimum visibility requirement can vary based on the specific airspace class and the intended flight operation, but for VFR at elevations exceeding 10,000 feet MSL, 5 statute miles is the mandated minimum visibility for safe flight operations.
