Ryanair Initial Practice Exam

Why are cabin lights dimmed during take-off and landing in darkness?

1. To save energy

2. To enhance the cabin atmosphere

3. To allow passengers' and CC's eyesight to adjust

4. To reduce cabin noise

The correct answer is: To allow passengers' and CC's eyesight to adjust

Dimming the cabin lights during take-off and landing in darkness serves the important purpose of allowing the eyesight of passengers and cabin crew to adjust to lower light levels. This adjustment is crucial in the event of an emergency, as the eyes need to be accustomed to the darkness to navigate safely if the need arises. In a panic situation or an evacuation, well-adjusted eyes make it easier for everyone to see emergency exits and other essential safety features in the dim conditions. This practice enhances overall safety on board and is a standard procedure followed by airlines to ensure the well-being of all passengers and crew. Several other answers may touch on aspects of cabin operations, but they do not address the critical safety reason for dimming lights during these key flight phases. For example, saving energy might be a consideration but is not the primary purpose in the context of safety. Similarly, enhancing the cabin atmosphere or reducing cabin noise are not relevant factors in this specific situation.
