FAA Part 107 Drone Practice Test

What is the operational significance of the magenta dashes on airspace charts?

1. Indicate an increase in elevation

2. Mark boundaries of controlled airspace

3. Indicate military operation areas

4. Show Class E airspace at the surface

The correct answer is: Show Class E airspace at the surface

The magenta dashes on airspace charts specifically indicate Class E airspace that extends to the surface. This type of airspace is important for several reasons, including its role in providing controlled airspace for aircraft operations that require less separation than in the higher levels of controlled airspace. Understanding that Class E airspace at the surface typically surrounds certain airports and areas allows pilots and drone operators to be aware of where they can and cannot fly, especially when operating a drone under Part 107 regulations. Such awareness is vital for maintaining safety and compliance with all aviation regulations. The other options, while related to airspace and its management, do not accurately represent the meaning of magenta dashes. For instance, they do not indicate an increase in elevation, mark controlled airspace boundaries, or signify military operation areas. Each of these aspects has different visual representations on aeronautical charts.
