Which statement correctly describes the vertical limits of Class E airspace over Magee Airport designated as a Federal Airway?

• A. 1,200 feet AGL to 17,999 feet MSL
• B. Surface to 5,000 feet MSL
• C. 700 feet AGL to 18,000 feet MSL
• D. 3,000 feet AGL to 20,000 feet MSL

Answer: (A)

Federal Airways are Class E airspace that starts at 1,200 feet AGL and extends up to, but not including, 18,000 feet MSL. Over Magee Airport, the vertical limits for a Federal Airway are therefore 1,200 feet AGL up to 17,999 feet MSL. The lower bound at 1,200 feet AGL places the airway in controlled airspace above the common traffic pattern level, while the upper bound stops just before Class A begins at 18,000 feet MSL. The other options don’t fit this structure, as they propose different starting levels or tops that don’t match the standard federal airway designation.
