How is the activation of Low Visibility Operations (LVO) indicated?

The activation of Low Visibility Operations (LVO) is indicated by illuminated amber light signs. This method ensures that drivers and personnel on the airside are visually alerted to the specific conditions associated with low visibility, which may require adjustments in procedures and heightened awareness. Amber lights are particularly effective in signaling a change in operational status, providing a clear and immediate visual cue that can be seen from a distance.

Using illuminated signs helps maintain safety and efficiency during periods of reduced visibility by ensuring that all individuals operating in the area are notified of the situation. Other methods such as flashing lights or voice announcements can be beneficial in certain contexts, but amber light signs are the standardized and recognized indication for LVO activation in many airport operations, providing a uniform approach to alerting drivers.
