Wingsuit flying

Wingsuit flying is an aerial sport in which a person wears a fabric suit that creates lift and drag, gliding after jumping from an aircraft or fixed object.

Wingsuit: A garment with fabric surfaces between the arms and torso and between the legs, used to increase a falling person's lift and drag. Its inflated fabric surfaces create the aerodynamic shape that makes the sport possible.
Skydiving: The activity of jumping from an aircraft and descending through the atmosphere, usually using a parachute. Aircraft-launched wingsuit flying is a specialized form of skydiving.
Wingsuit BASE jumping: A form of BASE jumping in which a person launches from a fixed object wearing a wingsuit. It is the fixed-object branch of wingsuit flying, with little time to recover from errors.
Human factors in aviation: The study of how human abilities and limitations affect safety and performance in aviation. Attention, judgment, and stress influence decisions made during a short, fast-moving flight.
Glide ratio: The horizontal distance traveled divided by the vertical distance lost during a glide. It measures how far a wingsuit pilot travels forward for each unit of descent.
Freefall: Motion through the air in which gravity is the main force driving a falling body's descent. Wingsuit pilots begin by accelerating in freefall before establishing a controlled glide.
Wingsuit skydiving: Wingsuit flying initiated by a jump from an aircraft, typically followed by parachute deployment. It is the aircraft-launched form of the sport and allows longer freefall flights.
Risk compensation: A behavioral response in which people adjust their actions when they perceive changes in risk. Greater confidence in equipment or skill can encourage more demanding flights.
Angle of attack: The angle between a wing's chord line and the direction of the oncoming airflow. Changes in body pitch alter the suit's angle of attack and its lift and drag.
Aerial perspective: The perception of distance, speed, and position from an elevated viewpoint in the air. Judging terrain and separation from other jumpers is a core practical skill.
