What does "Low" indicate regarding the altitude of a contact?

The designation of "Low" in relation to the altitude of a contact specifically refers to altitudes that are less than 5,000 feet above ground level (AGL). This categorization is important for various aspects of aviation, including communication, navigation, and air traffic control, as it helps pilots and air traffic controllers understand the vertical positioning of aircraft in relation to obstacles and airspace restrictions.

In aviation, altitudes are crucial for maintaining safe separation between different aircraft and ensuring compliance with airspace regulations. By defining "Low" as anything under 5,000 feet AGL, the aviation community creates a clear operational standard that pilots and controllers can rely on.

Understanding this classification aids in effective communication and enhances safety protocols, making it easier to identify potential issues such as terrain conflict or the presence of other low-flying aircraft.
