What does "PED" stand for in the context of airline regulations?

In the context of airline regulations, "PED" stands for Portable Electronic Device. This refers to a range of electronic devices that passengers can carry with them during a flight, such as smartphones, tablets, e-readers, and laptops. The term is widely used in safety and operational guidelines to denote the devices that must be managed in specific ways during different phases of flight, like takeoff and landing.

Understanding the classification of these devices is important for compliance with regulations aimed at ensuring passenger safety and minimizing interference with the aircraft's electronic systems. The focus on "portable" in the correct answer emphasizes that these devices are typically personal, battery-operated, and designed to be used on the move. Other terms provided do not align with the standard aviation terminology or regulatory practices, hence they do not accurately describe the category of devices referred to by "PED."
