What does an asterisk indicate in the communication portion of an approach plate?

• A. Tower is operational part-time.
• B. Tower is closed during the day.
• C. Weather minimums are changed.
• D. The approach is for military use only.

Answer: (A)

An asterisk in the communication portion indicates the tower is part-time. This flag means the control tower isn’t open at all times, so you should check the airport’s hours in the Chart Supplement to know when the field is actively controlled. If you’re planning to fly when the tower isn’t open, you’ll use non-towered procedures or coordinate with ATC as directed, rather than relying on tower services. The symbol isn’t about weather minimums or military use.
