USPA Skydiver's Information Manual (SIM) The United States Parachute Association's Skydiver's Information Manual provides basic skydiving standards (the Basic Safety Requirements) and recommendations agreed upon by USPA members for the conduct of safe and enjoyable skydiving. It also describes the programs USPA administers to recognize individuals for their expertise, ability to train others, and proficiency or tenure in the sport. Although the SIM provides much basic information for skydivers, each jumper should research further and consult USPA and industry officials, documents, and other produced media, as well as other reliable individuals for clarification and additional information.
