Which activities may take place within a warning area?

• A. Routine commercial flights
• B. General aviation practice approaches
• C. Meteorological research flights only
• D. Intensive military training, gunnery exercises, or weapons testing

Answer: (D)

Warning areas are set up to contain activities that could be hazardous to nonparticipating aircraft, often involving high-speed military operations and live-fire activities. The kind of operations you would expect inside a warning area are intensive military training, gunnery exercises, or weapons testing. Those activities create hazards that airspace users outside the military missions must avoid or exercise extra caution around. Routine commercial flights and general aviation practice approaches operate in other airspace with standard ATC separation, so they aren’t the typical activities designated for warning areas. Meteorological research flights can happen in other airspace as well and aren’t the defining use of a warning area. If you see a warning area on a chart, anticipate possible hazardous activity and plan to avoid or contact the appropriate authorities as needed.
