Question

(Refer to Figure 26, Area 5). The airspace overlying and within 5 miles of Barnes County Airport is

1) Class D airspace from the surface to the floor of the overlying Class E airspace
2) Class E airspace from the surface to 1,200 feet MSL
3) Class G airspace from the surface up to but not including 700 feet AGL

Answer 1

Without access to Figure 26, Area 5, the exact classification of airspace at Barnes County Airport cannot be determined. However, the general definitions for Class D, Class E, and Class G airspace suggest Class D is controlled airspace with an operating tower, Class E can start at the surface or a designated altitude and is controlled, while Class G is uncontrolled airspace from the surface up to a specified altitude.

Step-by-step explanation:

The question pertains to the classification of the airspace overlying and within 5 miles of Barnes County Airport as depicted in a certain aeronautical chart (Figure 26, Area 5).

The classifications mentioned are Class D airspace, Class E airspace, and Class G airspace. Each class of airspace is defined by specific altitudes and operational requirements. Class D airspace typically surrounds airports with an operational control tower,

Class E is controlled airspace not classified as Class A, B, C, or D, and it often extends from either the surface or a designated altitude up to, but not including, 18,000 feet MSL (Mean Sea Level), where Class A airspace begins. Class G airspace is uncontrolled and extends from the surface to the base of the overlying controlled airspace.

In the scenario provided, without the actual chart or additional context, it's difficult to determine the exact classification for Barnes County Airport. However, if the question were accurate and based on provided choices:

• Class D airspace would typically exist from the surface to the floor of the overlying Class E airspace. This means air traffic control is provided to all aircraft within this airspace during the operating hours of the control tower.
• Class E airspace from the surface would suggest the presence of air traffic control services starting right at the ground level, up to 1,200 feet MSL or the base of the overlying airspace, depending on what is depicted on the chart.
• Class G airspace from the surface up to, but not including, 700 feet AGL (Above Ground Level), would indicate that the airspace is uncontrolled up to that altitude, at which point a layer of controlled airspace begins.
