The NALF Fentress (NFE) Airport is in what type of airspace?

• A. Class B
• B. Class E
• C. Class D
• D. Class A

Answer: (B)

Class E is controlled airspace that typically covers airports with instrument approaches but without a control tower or surface-area control. It generally begins at a base of 700 or 1200 feet above the ground and extends upward to the base of Class A airspace at 18,000 feet MSL. The Naval Auxiliary Landing Field Fentress sits in airspace that is not designated as Class B, C, or D, so the airspace around it is Class E. This means IFR traffic is under ATC control and separation, while VFR traffic operates in this airspace under weather minimums appropriate for Class E and without needing a specific clearance to enter. The key idea is that Class E provides protected airspace for instrument procedures without the higher restrictions of the other classes.
