Final answer:
To determine the classification of airspace around Barnes County Airport referenced in Figure 26, Area 5, one must consult the specific aeronautical chart. Classifications such as Class D, Class E, and Class G have distinct characteristics and altitudes, but cannot be precisely determined without the chart.
Step-by-step explanation:
The student's question pertains to the classification of airspace near Barnes County Airport as depicted in a specific figure. Understanding airspace classifications is crucial for flight operations and for those studying aviation. Each class of airspace dictates the rules for flying, communications, and whether flight plans are necessary.
In this scenario, without the figure, it is impossible to provide a definitive answer. However, by using the information typically found on aeronautical charts, we can infer the following about each type of airspace mentioned in possible answers:
- Class D airspace typically surrounds airports with an operational control tower. It begins at the surface and extends upward to a specified altitude, usually a few thousand feet, ending at the floor of the overlying Class E airspace.
- Class E airspace often starts at either the surface or 700 feet or 1200 feet above ground level (AGL), depending on the area, and extends up to but not including 18,000 feet mean sea level (MSL), where Class A airspace begins.
- Class G airspace is uncontrolled and typically extends from the surface to the base of the overlying Class E airspace, either at 700 feet or 1,200 feet AGL.
Without visibility of Figure 26, Area 5, it's impossible to specify which of the provided options is correct. The student should cross-reference the specific figure on their aeronautical chart for an accurate determination of airspace classification around Barnes County Airport.
