FAA Ground School Practice Test

What is the maximum altitude that requires a minimum of 1 mile visibility for VFR flights at night outside controlled airspace?

1. Higher than 1,200 ft

2. Above 10,000 ft

3. Less than 10,000 ft

4. Equal to 10,000 ft

The correct answer is: Less than 10,000 ft

In the context of Visual Flight Rules (VFR) at night, regulations dictate the visibility requirements based on altitude and airspace classification. For VFR operations at night outside of controlled airspace, the regulations specify that a pilot must maintain a minimum visibility of 3 statute miles when flying above 10,000 feet. However, below that altitude, the visibility requirement is reduced to just 1 statute mile. The correct choice aligns with the regulation stating that for altitudes below 10,000 feet, a minimum visibility of 1 statute mile is indeed sufficient for VFR flight operations. This distinction is crucial because it dictates not only legal flight parameters but also safety considerations for pilots navigating under visual conditions at night. Understanding these altitude thresholds is essential for maintaining proper flight safety and compliance with aviation regulations.
