What altitude defines a contact as "Low"?

The definition of a "Low" contact is established based on its altitude in relation to the ground. When considering airspace classifications and how they categorize flight operations, "Low" typically refers to altitudes that are closer to the surface of the earth, often under 5,000 feet above ground level (AGL). This classification is important for various operations, such as managing air traffic and ensuring safety in lower altitudes where many general aviation flights operate, as well as factors like terrain and obstacles.

Choosing the option that states "Less than 5,000 ft above ground level" reflects this understanding of low altitude. In contrast, the other options suggest higher altitudes that do not align with the definition of a low contact, such as above 10,000 feet or within a range that includes higher altitudes. Hence, the definition best matches the standard concept of a low altitude contact to support safe and effective flight operations in the airspace system.
