What does the abbreviation DG represent?

The abbreviation "DG" refers to "Dangerous Goods" in the context of aviation and transportation. Dangerous Goods are items or substances that pose a risk to health, safety, property, or the environment during transportation. They encompass a wide range of materials, including explosives, flammable liquids, toxic substances, and radioactive materials.

In the aviation industry, strict regulations govern the handling, packaging, and transportation of Dangerous Goods to ensure the safety of passengers, crew, and aircraft. Understanding these regulations and the classification of Dangerous Goods is essential for airline personnel, as it helps prevent accidents and incidents related to hazardous materials.

In contrast, the other choices such as Domestic Goods, Delivery Goods, and Designated Goods do not have the same critical implications in terms of safety and regulations in the aviation context. Thus, "Dangerous Goods" is the appropriate and relevant term in this scenario.
