What are the cloud clearance and visibility requirements for a pilot operating under VFR in Class E airspace at 11,500 MSL during the night?

The cloud clearance and visibility requirements for operating under Visual Flight Rules (VFR) in Class E airspace at 11,500 feet MSL during the night are specified to ensure safe separation from clouds and adequate visibility for pilots. The correct requirements stipulate that a pilot must maintain a vertical distance of 1,000 feet above and below clouds, as well as 1 mile horizontally from them. Additionally, a minimum flight visibility of 5 miles is required.

These standards help prevent collisions with other aircraft and provide pilots with sufficient visual reference to navigate and avoid obstacles. Night operations demand more stringent criteria than daytime VFR to account for the reduced visibility and challenges associated with darkness. Therefore, the requirement of 1,000 feet and 1 mile at night is appropriate for ensuring safety in these airspace conditions.
