What is true regarding operating an aircraft under VFR in Class E airspace during the night portion of the flight?

When operating an aircraft under Visual Flight Rules (VFR) in Class E airspace during nighttime, the pilot must adhere to specific visibility and cloud clearance requirements. These regulations are designed to ensure safety during night operations, where visual reference can be more challenging due to reduced natural light.

In Class E airspace, the minimum visibility requirement for VFR operations at night is typically 3 statute miles, along with the need to maintain specific distance from clouds. The objective of these regulations is to provide a safe buffer that allows pilots to have adequate visual references to avoid obstacles and other aircraft.

This is in contrast to the other options, where the absence of altitude restrictions, or inappropriate visibility requirements, would not meet the federally mandated standards for night operations in Class E airspace. Understanding and adhering to these regulations is critical to ensuring flight safety at night.
