FAA Military Competency Practice Exam

What is the basic VFR weather minimum visibility required for operating a helicopter within Class D airspace?

1. 1 mile

2. 2 miles

3. 3 miles

4. 4 miles

The correct answer is: 3 miles

In Class D airspace, the basic VFR (Visual Flight Rules) weather minimum visibility required for a helicopter to operate is indeed 3 statute miles. This regulation ensures that pilots maintain adequate visibility to navigate safely and to visually avoid other aircraft and obstacles in their flight path. Operating under these visibility conditions allows pilots to make informed decisions about their flight, as they must be able to see and avoid other aircraft, terrain, and any potential hazards in their vicinity. It's essential for maintaining safety in mixed-use airspace, where both VFR and IFR (Instrument Flight Rules) operations may be occurring simultaneously. Further, the requirement for a minimum of 3 statute miles helps to align with the visibility needs associated with the takeoff and landing operations typically performed by helicopters, which may occur in varied environments. This regulation reflects the balancing act of safety, operational flexibility, and the recognition that helicopters often operate at lower altitudes compared to fixed-wing aircraft.
