The Advanced Freefall Program (AFP) at Skydive Chicago™ is an exclusive instructional program originally developed in 1984 by Roger Nelson. AFP has evolved over the years into the most progressive and complete curriculum used in the skydiving world today. The AFP curriculum has inspired USPA's requirements for self-supervision, thus producing more competent and confident skydivers. Unlike with other programs, AFP graduates have excelled in all aspects of the sport.
