Beginners knowledge on skysurfing
The competitor with the lowest total time at the end of the 5 rounds of competition is the winner. The performance is recorded using a very high powered camera on the ground, the competitor leaving the aircraft at 2200 mts and after a few seconds to build up speed commence their sequence. The world record time is currently 5.18 sec (Male) and 6.10 sec (Female). In skysurfing, a jumper attaches a board, similar to a snowboard or wakeboard but made specifically for skydiving, to his feet and performs aerial acrobatics in freefall, including flips and spins. Lew Sanborn and Jacques Istel started the first commercial drop zone and training center in 1959. While skysurfing is visually appealing and has been included in events like ESPN’s X Games, few jumpers still pursue this challenging discipline.
When leaving an aircraft, for a few seconds a skydiver continues to travel forward as well as down, due to the momentum created by the aircraft's speed (known as "forward throw"). The perception of a change from horizontal to vertical flight is known as the "relative wind", or informally as "being on the hill". Each event has a “working time” within which to repeat the sequence as many times as possible. During the tandem jump the instructor is responsible for emergency procedures in the unlikely event that they will be needed, therefore freeing the student to concentrate on learning to skydive. Skydivers reach terminal velocity (around 120 mph (190 km/h) for belly to Earth orientations, 150–200 mph (240–320 km/h) for head down orientations) and are no longer accelerating towards the ground. In freefall, skydivers generally do not experience a "falling" sensation because the resistance of the air to their body at speeds above about 50 mph (80 km/h) provides some feeling of weight and direction. Other training methods include static line, IAD (Instructor Assisted Deployment), and AFF (Accelerated Free fall) also known as Progressive Free-Fall (PFF) in Canada.
A demanding freefall exercise of specified turns and loops executed very precisely at speed, and under tight control. At normal exit speeds for aircraft (approx 90 mph (140 km/h)) there is little feeling of falling just after exit, but jumping from a balloon or helicopter can create this sensation. The panel of judges judge from the recording media.
The first three concern teams of either 8 or 4 plus their camera flyer performing a series of pre-determined patterns (formations) in a repetitive sequence whilst flying in a face to earth configuration. Style and Accuracy remained the primary discipline throughout the 1960s, and Relative Work continued to develop with the first 6 and 8 man formations being completed.
Many people make their first jump with an experienced and trained instructor – this type of skydive may be in the form of a tandem skydive. All of their work is recorded by the camera-flyer, and the panel of judges sit in front of a screen and make their individual decisions. Each competitor is timed from the start of the “series” to the end and time points are added for penalties such as a turn completed off heading or a loop deviating from the axis. At this point the sensation is as of a forceful wind.
The 1960s saw the beginnings of the first non-military drop zones, and non-military training methods. They developed a civilian training method with the belief that any intelligent person could be taught the basics of a parachute jump and jump the same day. They are judged on the number of correctly completed figures they make, and the team with the highest number at the end of 10 rounds of competition will be declared the winner.

Safety during workouts emergency
Technology has greatly helped aviation professionals when it comes to security. Modern equipment has made life easier for riders who venture into the sky to protect us from enemies.
1. What are these items?
This equipment simulates parachute for emergency exits. One such device is highlighted by its quality in graphic detail and faithful performance during simulation, because you can imagine yourself in midair and plummeted.
2. What do they do?
The sensations are basically the same for an emergency situation trying to make almost one real moment of danger.
3. How does it work?
The pilot is inside the device that looks like a real parachute and put a helmet and has a motion sensor. The pilot should be in full uniform as if in a confrontational situation in midair, making it even more faithful simulation.
4. When connected.
The device, when connected, is being monitored by an experienced trainer and a specialist in the system, which will be recorded all data collected during the simulated flight for further research.
5. What more simulator used by these professionals?
One of the most widely used equipment for testing the simulator is created by the company e.sigma. This simulator is called SOKOL and has a wide range of resources capable of solving problems that occur during flight. He has a different system for more complete simulator training for emergencies in the air.
6. The pilot.
The pilot, when the simulator should be fully equipped for safety and to look real. The pilot visualize the environment in a free fall and feel the difficulty of the force of the wind and rain through a "glasses" 3D quality equipped with a motion sensor, with which the pilot may make light or rapid head movements that not lose sight of the focus of the landing. In addition to the visual effects are sound effects that are nearly real simulate the sound of wind, rain and other climatic obstacle or not.
7. Virtual environment ..
The simulation begins with the rider "in" the aircraft, then it jumps, which actually is skipping a step equipment. But there is a simulation of an ejection cabin of an airplane, which in an emergency can make the difference between surviving or dying. The software allows to simulate different environments perfectly fall, terrain and weather, not to mention that before starting the workout safety instructor will program without knowing the pilot, some emergency situations that may occur in normal flight.
8. The equipment.
The simulation system consists of support where the rider is, computer monitoring, sensors that are connected to computers and the pilot, as well as specific software. The system is very interactive and easy to use, anyone can operate it. The simulator is suitable for specific training, therefore, are used to simulate situations of extreme emergency, however, are also used in military selections, ie, it is not a virtual toy, but a life saving device.
