Points for attention in skydiving

First, the main points to be paid attention to in skydiving

1. The weather conditions in the parachute area are good, and the visibility should be guaranteed. It is necessary to be able to visually identify the ground area on the aircraft. Clouds and fog are not suitable.

2. The skydiving height should not be too high, at most 1000 meters.

3. In principle, every soldier who takes part in the airborne operation must open his own umbrella, which is a matter of life. In fact, it is normal for recruits to help veterans fold.

The order of skydiving is fixed. Before boarding the plane, every paratrooper should be weighed, and the heavy one should jump first, because the heavy one falls quickly, and the one jumping behind may hit the umbrella of the person in front.

There is a special person on the plane who directs skydiving, called "sending an umbrella", that is, the one standing at the skydiving exit. If you hesitate, he will "send" you down.

6. Forced parachute opening is adopted for parachuting of airborne troops. Everyone we can see has a rope hanging on the chute behind his umbrella bag. This thing is called an umbrella lock. Once he jumps off the plane, he will open the umbrella immediately.

7. The parachute descends much faster than expected, dropping about 10 meter in one second. In order to avoid falling when landing, there is a standard landing action, which is difficult to describe. I have seen golf before. I feel that the lower body movements are similar, but the feet should be close together.

8, paratroopers in the process of falling, in case of emergency, such as the main umbrella can't open, should open the spare umbrella, can't see clearly in the smoke, should cross your arms to protect your head from collision, etc. There are requirements.

Second, the main ways of skydiving

Fixed-point skydiving:

The paratroopers jumped off the plane at a specified height and controlled the parachute to land in a predetermined area. The skydiving height is not less than 700 meters. When skydiving, set jumping targets on the ground and mark the landing area. Measured by the distance between the paratroopers' first landing point and the nearest edge of the bull's-eye, the closer they are to the bull's-eye, the better their performance.

Stepping on the bull's-eye is 0 meters (commonly known as "stepping on the spot"), and the result is the best. There are individuals and groups, in which group means that many people jump off the plane on the same route above the jumping target and land on the same jumping target. The competition is conducted for several rounds, and the sum of the fixed-point distances in each round is the paratroopers' (or teams') achievement, and the least one wins.

Skydiving:

Aircraft skydiving project. During the free fall from jumping off the plane to opening the parachute, the skydiver completes the required aerobatics in the air with the help of aerodynamics. The skydiving altitude is 2200 meters. There are four sets of prescribed movements, each set consists of four 360-degree turns and two 360-degree backflips.

Generally, the competition lasts for 3-5 rounds, and each jump makes a set of movements. The referee records the completion time of the whole set of movements (accurate to 1% seconds), and gives different "penalty seconds" to the non-standard movements according to the degree. Every achievement is the time to complete the action plus "penalty second".

The sum of the results in each round is the individual total score, and the one with less time wins. The stunt records the time to accurately complete a set of prescribed actions, and there are no irregular actions in it.
