FAA Ground School Practice Test

What is the minimum flight visibility for VFR flights above 10,000 feet MSL and more than 1,200 ft AGL in controlled airspace?

1. 3 miles

2. 4 miles

3. 5 miles

4. 6 miles

The correct answer is: 5 miles

For VFR (Visual Flight Rules) flights operating above 10,000 feet MSL (Mean Sea Level) and more than 1,200 feet AGL (Above Ground Level) in controlled airspace, the minimum flight visibility is set at 5 miles. This regulation ensures that pilots maintain a sufficient visual reference to navigate safely, increasing situational awareness and the ability to see and avoid other aircraft and obstacles. The requirement for 5 miles of visibility at these altitudes takes into account the increased altitude, where the airspace is less congested compared to lower levels, but still mandates a level of visibility that promotes safety in operations. This standard aligns with both FAA regulations and industry best practices, reinforcing the importance of having a clear view during flight when not relying solely on instruments.
