What is a .cup file?
File Extension Details
The CUP file extension is primarily associated with SeeYou, a comprehensive flight planning and analysis software suite developed by Naviter, which is widely utilized within the soaring, gliding, and paragliding communities. These files serve as specialized data containers that store geographic information essential for aviation navigation, specifically focusing on waypoints, airfields, and competition task definitions. Structurally, a CUP file is a plain-text format, often following a comma-separated value (CSV) logic, which makes it both lightweight and highly compatible across various hardware devices. Each entry within the file typically includes critical metadata such as latitude and longitude coordinates, elevation data, airfield radio frequencies, and specific turnpoint attributes. Because of its open-text nature, pilots and flight planners can easily modify these files using standard text editors or spreadsheet applications. The format has become a standard in the air sports industry, allowing pilots to seamlessly transfer navigation data between desktop planning software, dedicated flight computers, and mobile navigation apps to ensure safety and precision during cross-country flights and competitive racing events.
