For how long must ATIS broadcast unauthorized laser illumination events?

Explanation:
When unauthorized laser illumination occurs near an airport, ATIS must continue broadcasting the event for one hour after the last report. This keeps pilots informed about a potential glare or distraction hazard during critical flight phases, such as approach and departure, giving them time to adjust plans or remain vigilant. The one-hour window provides a practical balance: it lasts long enough to cover subsequent reports and repeated activity, but isn’t so long that the information becomes stale or cluttered with outdated risk. After that hour, the message can be updated or removed unless new reports indicate the hazard persists.
