How do you verify if an aid to navigation is functioning properly?

• A. Check the light's brightness
• B. Count flashes over a minute
• C. Monitor radio signals
• D. Assess sound signals

Answer: (B)

To verify if an aid to navigation is functioning properly, counting the flashes over a minute is a key method because it allows you to determine if the light is operating according to its established characteristics. Each aid to navigation has a specific flashing pattern that is documented in navigational charts and guides, enabling mariners to identify it during their navigation. By counting the flashes, you can confirm that the light is emitting the correct number and sequence, which is essential for ensuring the aid is both visible and identifiable to vessels. This method is particularly important for visual aids, as differences in flash patterns can indicate malfunctions or maintenance needs. Ensuring the proper operation of these aids is vital to safe navigation, especially in areas where visibility may be limited. In addition to this method, assessing other factors such as sound signals or radio signals can play a role in navigation, but the primary verification for visual aids remains the counting of flashes.
