How frequently should caution be broadcast for a laser event?

The correct response is based on established protocols for improving safety in air traffic control during laser events. Broadcasting caution every 5 minutes ensures that both pilots and air traffic controllers remain aware of the potential risks associated with laser activities in the vicinity. This frequency strikes a balance between providing timely updates and preventing unnecessary alarm.

Maintaining awareness of ongoing laser activities is crucial because such events can impair pilot visibility and lead to hazardous situations. By issuing cautionary broadcasts every 5 minutes, authorities can effectively communicate current conditions without overwhelming the communication channels or desensitizing personnel to important safety information.
