Can any pilot practicing BASE Jumping leap off a cliff or do you somehow train for this? Technically, all that's needed is money to buy a wingsuit and a parachute, and a cliff. Without training, they might manage to get the wingsuit operating properly for some of the flight, but I wouldn't want to see the odds of a successful landing. The general training arc would be to learn wingsuiting from an aircraft (like a regular skydive), and build up hours/experience flying a wingsuit in clear air (and deploying a parachute several thousand feet above the ground), before going into wingsuit base jumping (and build up experience there before going into prox).
