The correct method of safety belts for aerial vehicles 1. After adjusting the seat, sit straight. Grab the lock tongue on the head of the harness, pull the harness down along the body, do not kink the harness, and then snap the latch into the buckle. At this point, remember to slam the tongue again and make sure the seat belt is fully locked. Don't tilt the seat back too far. Otherwise, the seat belt will not stretch and wind properly. 2. The seat belts in different locations. A common shoulder harness should be tied to the shoulders, across the chest and must not be placed under the arm. The waist belt should be as low as possible, close to the lower part of the hip and not tied at the waist. The advantage of this system is that the impact force at the time of collision will act on the pelvic bone to ensure the stability of the human body. After the waist belt is fastened, it is better to pull down the waist belt at the buckle end and pull the shoulder belt upwards. 3. Do not press the seat belt on a hard or fragile object. Do not put glasses, keys, mobile phones, etc. on the chest pocket.
