Completely updated for 2025, the Skydiver’s Information Manual (SIM) is the premier source for information on how to skydive safely and enjoyably, whether you’re just learning to skydive or have been in the sport for decades. The United States Parachute Association—a not-for-profit membership organization run by skydivers, for skydivers—produces the SIM as the foundational textbook and reference manual for all skydivers, from beginner to highly experienced. The SIM provides the organization’s Basic Safety Requirements (the commonly accepted safety standards to which USPA members must adhere), and well as more in-depth information about the sport, including:

• Curriculum for student skydivers (the USPA Integrated Student Program)
• General recommendations for all skydivers on emergencies, currency training, equipment, weather and more.
• Recommendations for advanced skydiving such as freefall formation flying, night jumps, wingsuit flying and advanced canopy piloting.
• Exhibition jumping
• Licenses, ratings and awards programs
• Guidance on Federal Aviation Administration documents that relate to skydiving
