Which event requires both the captain and first officer to complete a pilot debrief within 24 hours?

A laser strike incident requires both the captain and first officer to complete a pilot debrief within 24 hours due to the serious safety implications involved. Laser strikes can potentially impair pilots' vision and distract them during critical phases of flight, which poses a significant risk. Prompt debriefing allows the flight crew to share information, document the incident accurately, and report any safety concerns to relevant authorities. This timely communication is essential for ensuring ongoing safety measures and preventing future occurrences.

In contrast, while engine failures, flight diversions, and weather-related delays are significant events, they do not specifically mandate a debrief within the same stringent timeframe as laser strikes. These incidents may still require reporting and discussion but typically follow different protocols.
