Use the chart to estimate your freefall time according to your approximate terminal velocity and the distance in freefall.The velocity of the free-fall object is defined through the equation. Subtract your opening altitude from your exit altitude to determine the length of your freefall. It is given that it has been falling for two seconds.Determine your approximate terminal velocity by taking actual measurements of jumps with known exit and opening altitudes (this can be done by timing video tapes, by having someone on the ground time the skydive, or using a recording altimeter).To determine the approximate amount of freefall time to expect on a jump and to log a realistic amount of freefall time for a jump, use the following procedures:.50 mph (73.3 feet per second) for wing-suit jumps.160 mph (235 feet per second) for vertical head-down or standing orientation.120 mph (176 feet per second) for belly-to earth orientation.The chart lists freefall times based on three different typical terminal velocities and provides an exit altitude reference for 3,000-foot openings.skydiving discipline, e.g., vertical orientations.This page exists due to the efforts of the following people. total weight of the jumper including equipment Solution of the falling body and distance passed tasks.Many factors affect the rate of fall or terminal velocity in freefall.The amount of freefall time logged for each jump should be actual time.Each skydiver should log every jump made, including the amount of freefall time experienced.The following table will assist in estimating the approximate amount of freefall time to be expected from a given altitude and in logging the correct amount of freefall time for a given jump.Hazards Associated with Movement JumpsĦ-3: Freefall Rate of Descent and Time Table A.
