Which of the following is typically NOT found in a seat back?

The choice indicating that a charging dock is typically not found in a seat back is correct because charging docks are generally not a standard feature in aircraft seating configurations. In many aircraft, the seat back is designed primarily to accommodate safety necessities and passenger comfort, so items such as sick bags, menu cards, and safety cards are commonly placed within easy reach for passengers.

Sick bags are provided for passenger convenience, allowing for easy access should the need arise during the flight. Menu cards are included to inform passengers of the meal options available on board. Safety cards are a crucial part of in-flight safety protocol, providing essential information about emergency procedures and equipment location. These items are all integral to passenger safety and comfort, which is why they are typically included in a seat back.

In contrast, while the demand for charging ports has increased in modern aircraft to accommodate personal electronic devices, they are usually integrated into armrests or common areas rather than stored in the seat back itself, which maintains space for the more critical materials mentioned. Therefore, the absence of a charging dock in the seat back aligns with the usual design and operational practices within the airline industry.
