Lead unfolding process

The invention relates to a lead unfolding process which comprises the following steps of: unfolding a middle-phase primary leading rope; utilizing the middle-phase primary pulling rope to unfold a secondary leading rope; utilizing the secondary leading line to unfold a sub-secondary leading rope; utilizing the sub-secondary rope to unfold the middle-phase leading rope and utilizing the middle-phase rope to unfold two ground leads, two lead guide ropes and a middle-phase leading rope by once pulling. The two ground leads, the two lead guide pulling ropes and the middle-phase pulling rope are unfolded through once pulling, therefore, the process can reduce the number of times of flights of a paramotor, improves the working efficiency, saves the energy and the cost, and increases the safety.
