How long does the flashlight stay activated?

The flashlight used in emergency situations by flight attendants is designed to provide adequate illumination for a significant length of time while ensuring the safety of passengers. The correct duration for which the flashlight stays activated is between 30 minutes to 4 hours.

This range reflects the need for the flashlight to be reliable during critical emergency scenarios, such as evacuation procedures or power outages. A duration of this length allows flight attendants to navigate safely and assist passengers in low-light conditions, ensuring that they can lead evacuations or provide guidance when necessary. The design takes into account the importance of maximally utilizing battery life while maintaining operational readiness in the event of an emergency situation.

Other options indicate either excessively short or unreasonably long durations, which would not adhere to the standard intended for aviation safety equipment.
