What does the term "inflight entertainment" refer to?

The term "inflight entertainment" specifically refers to an entertainment system that provides both audio and video options for passengers during their flight. This setup allows travelers to enjoy a variety of content, such as movies, music, television shows, and games, enhancing their overall flying experience. Passengers appreciate these options as they provide a way to pass the time during longer journeys, making flights more enjoyable.

In contrast, the other options provided do not capture the full scope of inflight entertainment. For example, a system that offers only audio would be limiting and would not encompass the video components that are an integral part of modern inflight entertainment systems. A service focused solely on customer information would not include the leisure aspect of entertainment. Lastly, a manual outlining entertainment options does not represent the actual experience or system itself but rather serves as a guide to inform passengers of what is available. Therefore, the comprehensive experience offered by an audio and video system defines the essence of inflight entertainment.
