What is the purpose of the flashlights on the aircraft?

The purpose of the flashlights on the aircraft is primarily for use in evacuations or during power failures. These flashlights are crucial safety tools designed to ensure that both crew members and passengers can effectively navigate the cabin in low visibility situations, such as during an emergency evacuation or when the aircraft experiences a loss of electrical power.

In the case of an emergency, having reliable sources of light helps to guide people towards exits, enabling them to evacuate the aircraft more quickly and safely. The presence of these flashlights ensures that safety protocols can be followed even in the dark, minimizing chaos and potential accidents during critical moments.

Other choices do not reflect the primary safety function of these flashlights; for instance, while they may be used occasionally for routine checks or during flights, their main design is focused on emergency scenarios.
