What is a SUA file? A SUA file is a data file saved in the Special Use Airspace (SUA) format used by glider pilots to plan and analyze flight maps. It contains information about blocks of airspace, such as the type of airspace, classification, hours of operation, latitude and longitude position, and suggested flight altitude.

Glider pilots would utilize these devices to plan flights, but with the advancement of GPS technology, these instruments and SUA files are seldomly used. Some types of airspace information include: TYPE - Defines the type of airspace with an abbreviation, which includes "R" for Restricted, "P" for Prohibited, and "Z" for Training Zone. ACTIVE - Defines the normal hours of operation in the airspace. BASE and TOPS - Defines the allowed flight altitude. POINT - Defines the longitude and latitude coordinates.
