Which of the following is a true example of the visual controlling phase?

• A. Hand and arm signals, lights, panels, mirrors, smoke
• B. Verbal commands only
• C. Radio calls
• D. Beeps

Answer: (D)

The visual controlling phase relies on signals that can be seen, not heard. It uses visible cues to guide the aircraft, such as hand and arm signals, lights, panels, mirrors, and even smoke to communicate intentions or directions. Beeps are auditory signals, which belong to other control methods, not the visual phase. So the best example of the visual phase is the use of visible signals like hand signals, lights, panels, mirrors, or smoke.
