For how long should general caution be broadcast for a laser event?

The appropriate duration for broadcasting general caution following a laser event is 20 minutes. This practice is in place to ensure that all relevant air traffic and flight operations are aware of potential hazards related to laser illumination, which can pose significant risks to pilots and aircraft safety.

The reason for this particular timeframe is based on standard safety protocols that aim to maintain heightened awareness among pilots and ATC personnel regarding the possibility of ongoing or similar occurrences. This 20-minute window allows sufficient time for the effects of the laser event to dissipate and for any subsequent clarification or measures to be taken.

While the other durations might seem reasonable, they do not align with established procedures designed specifically to mitigate risks associated with laser incidents effectively. Each duration is carefully considered in relation to air traffic dynamics and safety standards, emphasizing the importance of structured communication in ensuring safe flight operations.
